I am a bit confused, that you call both E and F the "free energy". Is it the same? That would mean we obtain recursion relation for the free energy. Since F ~ ln(Z) and Z~integral over exp(~Z).

great great great video!

I like your style

Thank you for interesting lecture. I am wondering, if there was any difference apart from concentration between top and bottom (red and blue)? If no, so why the bottom is not just inverted top one? Why the bottom pattern is formed in vermicular structure, whereas top one as droplets? Thanks.

: ))) Loved your lectures. Insightful and fun both at the same time. 💚💙❤

which book you follow

Is Φi(x) same as Φ(xi) ？I am confused. As I comprehend, Φi(x) is the collection of function in term of x. Φ(xi) is a function in term one designated variable x e.g. x=2. Would you clarify them?

I am finding these lectures very helpful to getting started with landau-Ginzberg theory. Thanks a lot David!

Mmmmm😊

Thank you so much for publishing this lecture, and for having a 'what's actually happening' approach. I appreciate it very much.

I am Dyslexic, and find it very hard to understand most lectures, i understood everything in this lecture first time

such a cool equation, cheers mate!

Hmmm can the critical exponent be irrational? and given a Hamiltonian, can we tell which universality class it belongs to?

Good

Use Krypton bottles. That got the Super out of the man, as well. XD

9:43 How about googling "analysing social networks by tensor decomposition"?

where can i see the source code?

Great video!

So explanatory, thanks

great video!

There sure is difference between a gas and a liquid, e.g. surface tension, which does not exist for a gas.

Every video in your channel appears very useful and must watch for me, Why is that?

i didn't umderstand your english sir its so damn difficult for foreigner

can you please provide the slides? for theoritical part!

A bit late here but I wonder if you have any more videos on Block Copolymer structures? Your video was very helpful, and I'm currently working on research in Lamellar BCPs.

great! lifesaver

Sir, could you provide pdf of this please.

A curious question... Can a superfluid be maintained in its zero friction state over an airfoil surface with an appreciable effect on laminar flow with some other surrounding gas? Something like a micron thin film over a surface allowing shedding of any surrounding envelope? I suspect such could have some rather interesting applications, if it can effectively eliminate drag without too much of an effect on lift. Might be a way to go supersonic with no (significant) sonic boom, and perhaps "super-gliding" if the reduction in drag really is that significant. Maybe a question more about mechanical properties than physics or related quantum intricacies, but somebody with more access/experience with such a peculiar substance is likely to know or have means of experimenting. I figured such may also require quite a bit of liquid helium as a consumable due to shedding, so it may have some practical issues to the approach anyways. (Information on superfluids in some regards is limited, so there's not too many places to ask.)

Insightful.

Sir, Please give some reference books links for critical exponents.

Thank you for your explanation.

nice. But where are the remaining lectures?

Nice simulation. How does it compare with say the more commonly used method of actually solving the NS equations? How's the performance?
