i have seen many videos of around one hour of duration and i couldn't understand what a topological insulator was. This guy simply explained it in less than 2 minutes and i got it perfectly. Thank you so much
I had the luck of having this lecturer as a teacher in "Physics by the lake" school, 2018. Chris Hooley is indeed an amazing teacher and communicator .Unfortunately, therer aren't many videos of him on CZcams!
Oh my god thank you for putting this into words what "topologically protected" means. I was searching forever and did not find any concise description!
This video is perfect. It does exactly what it promises to do, namely answering the question posed in the title, and that in a great well presented way. So ya, thanks, bow tie man ! :D
The topological invariant of a TI would be it's insulating and conducting properties. The TI can be physically changed but, will always exhibit these properties. The topological invariant of a donut is that it has one whole.
Thank you, bow tie accent man. This is exactly what I needed.

I know him from my PhD days. Crystal clear explanation.
great simple and clear explanation of TI !
Wish there was "and here how we can use this effect.." in the ending
Nice clean explanation, subbed, ty!

great explanation 👍

Nice job, thank you sir
Very good explanation ❤❤❤great job 👍👍👍👏👏👏
Well understood!
What is a topological invariant? Which is the topological invariant in the case of a topological insulator?
The topological invariant of a TI would be it's insulating and conducting properties. The TI can be physically changed but, will always exhibit these properties. The topological invariant of a donut is that it has one whole.
Thnx. It was great.
Excellent!
interesting indeed
Well, that was clear enough 😁
Oh my God! Physics is experincing its down time
By that you mean?
look at how cheap the above phenomenon is ( compare to superconductivity, or other old experiments)

Almost physically-meaningless distinctions. Electrons do not exist as "thin films" - condensed matter does.
