How Two Physicists Unlocked the Secrets of Two Dimensions

Condensed matter physics is the most active field of contemporary physics and has yielded some of the biggest breakthroughs of the past century. But as rapidly as technology has advanced, scientists have only scratched the surface. Now for the first time, Jie Shan and Fai Mak, a married couple of physicists at Cornell University, have figured out a way to create artificial atoms in the lab, opening the door to a new era in research.

This channel is so high quality and criminally under-watched. Another A+ video

I love the realism of his attitude. He acknowledged that this work may not have much real world scaling, but the concepts themselves are what is important.

I saw a video by Veritasium where he showed the Moiré lattice pattern, he held two transparent sheets of a honeycomb-ish pattern overlapping, and I remember seeing the different shapes and structures emerging, being completely fascinated! I got way too excited about it and felt silly. I'm a 30 year old woman, and I wanted to have these sheets myself to explore these patterns, they're beautiful. I knew there was something to it, and this video makes me very, very happy! Can't wait to see more from this research and channel, I'm a new subscriber.

Almost like they're making their own "fields" and then creating particles by putting different levels of energy into those "fields." Amazing.

Props to the teams including postdoc and phd students in the research, because we know they are the unsung contributing heroes

[err_go]

Whoa. I love this type of minimalist approach to problems in general. It's so elegant here. Very inspiring!

[NoNTrvaL]

Never thought I would see Moire patterns being mentioned here. Absolutely amazing video!

[coniccinoc]

I hope this couple is blessed with many children.
Propagating their genius code could be a force of good for civilization.

So many developments like this seem hypey. But this one, dropping to 2D is such a beautiful simplification, lends itself to sane-time computer simulation. The moiré bit, again, beautiful. Reminds me a lot of X-ray crystallography, maybe similar potential for discovering how stuff works.

[handlenotset]

astonishing! who wouldve guessed moire patterns could unlock this new world! bravo to Jie Shan, Fai Mak and their students

[naxar]

My physics are 30 years old, but/and thanks for keeping me updated. What a great channel, I agree with the man who said it was underwatched. And what wonderful people these 2 are.

[charliecrome]

what a genius idea. you can tell theyre passionate about their field too by the smiles on their faces when they talk about it

[officiallukeforester]

May I just say I am delighted how quickly this video followed the last!! I can’t get enough of this channel!!

[Mutual_Information]

This channel covers such premiere topics.. with beautiful animation and natural narration.. it's a future 10M+ channel.

[robinhodgkinson]

Wow. This feels like game changing research. New technology here we come. Material sciences are fascinating.

[pacobrezel]

A while ago I read an article also about a similar moire experiments and where by accident was discovered that under a particular angle at room temperature electrons move without loss through the material. In the topology of materials and their setup there is still quite some exploration of new physics possible

[gregparrott]

As another person commented..."WHOA!"
This sounds every bit as much a potential for experimental discoveries as the introduction of the microscope, electron microscope, telescope, oscilloscope, etc.
It may offer even more fundamental utility in linking geometry (2D planes, Moire patterns, alignments between planes, etc.) to the physics of materials
I don't think that has previously even been considered as an avenue for exploration

[Protocol-One]

This channel deserves more credit, hands down has the best science in a nutshell consumer content on YouTube.

[prithviraj]

So they've created artificial Atoms (artificially simulated atoms) within the stack of semiconductor material and when applying voltage an atom changes its properties from one atom element to another.
Marvelous!!!

[thrasherca]

I'd love to see a more in-depth video about the mechanics of how the stacked sheets create virtual atoms!

What are the limitations? Are there any conceivable functional/commercial uses (beyond research).

What an exciting development in physics research! I'm surprised this is the first I'm hearing of this technique/technology.
