In particular, scalable quantum technologies require the development of controlled approaches for the direct planar integration of quantum emitters with atomic scale resolution. In this work, we propose and investigate an alternative route to engineer defect emitters that are of atomic scale. Specifically, we demonstrate theoretically and experimentally that localized defects in two-dimensional layers create trapping potentials in which bound complexes are formed that emit in a range of about hundred meV below the free exciton line in MoS2.

The precision with which defects are localized is expected to be solely limited by the resolution of the helium ion beam. Compared to strain engineering, a controlled exposure with helium ions is superior due to the sub-nm beam size that is very well suited to structure 2D materials at the nanometer scale Here, we demonstrate that the encapsulation of helium irradiated MoS2 monolayers with hBN allows one to define defect emitters with very narrow linewidths.

Our spectroscopic observations are consistent with photon emission that stems from defect centers in MoS2, which serve as highly localized exciton emission centers.

The interpretation is corroborrated by analyzing in detail the lineshape of the new emission peaks. This allows us to determine the interaction of the localized exciton with phonons, which indicates that the emitters are localized on a nanometer scale.

Results Defect creation in a van der Waals heterostructure by helium ion irradiation The van der Waals heterostrutures studied in this work are iteratively stacked onto Si substrates covered with nm thermally grown SiO2. Onto this substrate we first transfer a multilayered hBN virtual substrate, and a single layer of MoS2. The a1-p singlet state is situated within the valence band. For excitation, we use a cw laser with a photon energy of 2. Representative luminescence spectra from five randomly selected positions of the exposed sample that show defect emission are presented in the bottom of Fig.

These features are superimposed on the so-called L-peak that is observed in monolayer MoS2 4 , 5 , 35 and has recently been attributed to the presence of sulphur vacancies 36 , The sharp spectral features are spatially localized and require helium ion exposure of MoS2 and the subsequent encapsulation with hBN. We also show the spatial occurence of emitters in three energy bins cf.

So far, single-photon emitters have been found at sample edges or folds, where the bandstructure is strongly influenced by the crystal boundary, coupling of atomic-orbitals by local symmetry breaking or strain 1. By contrast, we find spectrally sharp emitters homogeneously distributed all over the 2D sample; this is a direct consequence of the helium ion exposure.

MoS2 exhibits several defects, most prominently single sulfur vacancies and single molybdenum vacancies 38 , 39 , Here, we concentrate on molybdenum vacancies VMo, although we are aware that the discussed defect emitters might be of character that is more complex. The vacancy states have a trigonal and mirror symmetry between the two layers of the sulphur and the molybdenum layer In turn, two singlet a1 and two doublet e states are expected for all cases.

We find that all presented states are stable and relaxed within our DFT framework. We interpret the experimentally observed sharp emission lines as resulting from excitons that also involve particle-hole excitations from the defect state orbitals However, the DFT calculation does not consider the binding energy of the exciton that is comprised of the different electronic orbitals with a complex distribution of weights and varying momentum dependencies An optical micrograph of the flake prior to exposure is presented in Fig.

Subsequent to exposure, the nano-structured MoS2 monolayer is fully encapsulated in hBN. We record a spatially resolved PL mapping of the treated areas with a small step size nm. The corresponding spatially resolved and spectrally integrated PL mapping is presented in Fig. Enhanced PL emission is clearly observed at the irradiated spots.

Moreover, from the data, we extract and overlay the occurence of localized emission XL with the PL mapping highlighted in orange. We find that localized emission is activated at all positions that are exposed by the HIM. Conversely, sharp line emission is not observed from the unexposed regions. Corresponding spectra of five exposed positions are presented in Fig. Each spectrum exhibits a small number 1—3 of emission lines that are completely absent in unexposed areas cf.

You learn to walk before you try to run. Start with the empty bar and add a little weight each workout. As the weight increases so will your experience, comfort and confidence with the weight. Keep your thighs and feet aligned to avoid knee injuries. Your gym may not have a Power Rack or even a bar. Substituting any exercise will make the program less effective.

There are no better exercises than these fives. The key is to use proper form by using a complete range of motion. A half Squat will not build legs like a proper Squat will — your muscles are only working half the movement.

Use the same range of motion on every rep, set and workout regardless of the weight. Keep it constant. Stick to it. Bench or Overhead Press next. This gives your legs and lower back rest before you need them again on Barbell Rows and Deadlifts.

Your lower back and legs will be tired from Squats. You need them for Rows and Deadlifts. Starting with Deadlifts tires your lower back for Squats. Squats tire it for Deadlifts too. Sticking to the same exercise order every workouts also makes it easier to track improvements. Your goal is to build it.

Get used to it. Do five sets of five on one exercise before moving to the next one. The Power Rack may not be free when you arrive in the gym. Just ask how much time he has left. Great — you just wait. Gather your plates and stuff. Warmup for Squats maybe with a few stretches. Sometimes he just started or still has many sets to do. Waiting would take too long. Ask if you can join and do your sets while he rests inbetween. In fact this is how I met my early mentor.

This is the best way to make friends in the gym. Again — do it. Deadlifts use more muscles. The weight is heavier and each rep starts from a harder dead stop.

Heavy weights trigger your body more to gain strength and muscle. It has to get stronger and build muscle to lift the bigger weights.

More Progress. You can add 2. This means you can apply progressive overload longer without plateauing. Better form.

The shorter set makes it easier to stay focused on lifting with proper form. This increases your lifting efficiency and safety. You can lift heavier weights without getting injured. Five sets also give you almost double the form practice than three sets.

The more you practice proper form, the more efficient you become. Each set depletes your ATP stores. So resting longer between sets gives you more ATP for your next set. Short rest times make you sweat more and cause more pump. But they limit how heavy you can go by forcing you to lift with depleted ATP stores. Rest longer so you can go heavy. You can fix that by only resting longer when needed.

Keep longer rest times for your hard work sets. It tells you how long to rest between work sets, warmup sets and exercises. It suggests different rest times if your last set was easy, hard, or if you missed reps. Stay focused between sets. You can sit on a bench, but I like to stand. Review your form if you just taped yourself. Maybe visualize yourself doing your next set with perfect form.

Lifting slow is no good because it wastes strength. You must be in control of the bar at all times. But as you gain experience you can start accelerating the bar on the way up. Always lower the bar under control. Control it on the way down so you can maintain proper form. Lifting slow causes more pump and fatigue.

But it also limits how heavy you can go. You can lift heavier when you lift fast. Your lighter warmup weights will move fast. The bar can sometimes move slowly on hard reps aka grinders.

Take your time between reps. Rest a second before doing the next rep so you can get tight and take a big breath. This will also give you some recovery. Breathing The general rule is to take a big breath before you do the rep, hold it while you do the rep, then exhale when you finished your rep. Your blood pressure will increase when you hold your breath like this. But your body will get used to this, especially if you start with the empty bar and work your way up slowly.

Your heart is a muscle, and it will get stronger like all your other muscles. Ignore people telling you to inhale on the way down or exhale on the up and similar bullshit. All of that does release pressure, but it also weakens your torso. It makes your lower back more prone to injury. The point of taking a big breath and hold it, is to create pressure in your abdomen. This pressure increases support for your lower back. It makes your lower back safer and less likely to get injured.

Exhaling during reps does the opposite. Lower the weight to the floor and wait for the bar to be still before pulling the next rep. Use this rest to reset yourself — neutral spine and chest up.

Then take a big breath and pull. Squat the weight up and lock your hips and knees. Bench the weight up and lock your elbows. Then rest a second to get tight for the next rep. Then do your next rep. Lower the bar to your chest. Rest a second to get your forearms vertical to the floor and raise your chest. Then take a big breath and press the next rep. An advanced technique that works well on the Bench and Overhead Press is to press several reps with one breath.

But you must be able to hold your breath for reps for this to work. Rest days are crucial to get results on this program. But your body needs time to recover, gain strength and add muscle. Workouts also cause fatigue. They increase your strength, fitness and endurance in the long-term. But in the short-term they tire your body, muscles and mind. You need rest days to start your next workout fresh. Your legs will still be tired for Squats , shoulders still tired to press, back still tired to pull.

This will make you struggle to lift more weight. Once in a while is fine but every week will hurt your progress. A walk or light jog is fine. A marathon is not. Avoid high intensity activities where you go all out.

Your body is already used to it. If you never biked to work, probably a bad idea to start now. So add weight to it. Here are the increments to use: Squat: 2. Deadlifts use big muscles so you can handle more. And the progress graphs will keep you motivated.

Signup to my daily email tips to get the spreadsheet. Just click here. Ask them to get a pair or download your own set. Put it in your gym bag and take it with you every time. Small plates take no space and weigh little.

This is asking for bad form, uneven loading of your body, and injury. Just get small plates. The weight is heavier as a result. The weight is lower which makes big jumps harder. This is too much, too soon.

It makes you miss reps and plateau. Small plates delay plateaus. So get a pair of 1. Then get fractional plates of 0. The lighter you are, the more you need this.

The program progresses faster when using kg than lb.

Reclaim Your Heart by Yasmin Mogahed

This accelerates your progress when the empty bar feels too easy to start with. But lower the increments before you struggle to get your reps. So stick to the progression and increase the weight anyway.

Starting Weights Start light so your body can get used to Squatting, pressing and pulling three times a week. Focus on lifting with proper form meanwhile. This will prepare you for the heavy weights later. Starting too heavy will cause soreness. One skipped workout often turns into two skipped workouts. This ruins your motivation and usually ends the program.

But this is irrelevant. Starting too heavy also causes plateaus. Of course lifting heavy is better. But lighter weights trigger your body to gain strength and muscle too. Instead of practicing proper form with easy weight, you must lift it at all costs to get your reps. Starting heavy is trying to accelerate your progress. You think it will make you stronger faster. Your starting weights depend on your strength and experience.

You may look ridiculous for a while, but the weight will increase each workout. Each rep must start from the floor. If the empty bar is too heavy to start with, then use a lighter bar. This is a common issue with females who have less upper-body strength. Add weight each workout. The program will get you stronger. If the starting weight is too light, you can fix that by using bigger increments for a couple of workouts. Instead of adding only 2. What you lose is time spent working on proper form with lighter weights.

If you make the mistake of starting too heavy, you should go to the gym anyway for your next workout, but lower the weights.

Warmup Do several lighter warmup sets before your heavy work sets. Warmup with the empty bar. And they prepare you mentally for the heavy weights to come. Never jump into your heavy work sets without warming up first. Always warmup by doing several lighter sets first. You must still do lighter warmup-sets. Also, too much cardio pre-workout will pre-exhaust your legs for Squats. Skip the cardio and do lighter warmup sets — it will save you time.

The proper way to warmup is to start with two sets of five with the empty bar. Only rest after the last one. The weight is too light to get injured plus doing extra sets could tire you out. Or you can use one of those free warmup calculators online.

But they all suck. The mistake they make is to make you do five warmup sets regardless of how heavy your work weight is. Terrible — you lifted lb before you even started.

Too many sets, too close weight jumps. This wastes strength.

Too big jumps of lb, too little sets. Smaller weight jumps. Try it. This means the warmup calculator in my app is different. This is more effective. Warming up makes your workout longer. The stronger you are, the heavier your work weight, and the more warmup sets. This way you have full ATP available before doing that heavy set.

On your other warmup sets, just add weight and go. Use the warmup rest timer in our app — it tells you how long to wait so you can focus on lifting.

Your workout starts with your warmup. Put the same focus and effort into them. If you do it right. This gives you more reps to practice proper form. It also increases how much Deadlifts you do. All of this takes care of your recovery.You can actually come back stronger from the extra rest. Customers who bought this item also bought.
