This is cool stuff. I was introduced to this effect in quantum field theory II (a model using a schrodinger field) randomly and I remember having to search up several resources on this. It's crazy how we can still describe superconductivity with relatively simple math.

[@PrettyMuchPhysics]

That‘s true. Sometimes immensely complicated physics can be described by a single line of equations. The beauty of physics :D

I have a condensed matter final in 2 hours and this is exactly the kind of content I need.

I love this channel, so good. Great video by the way!!

[@PrettyMuchPhysics]

Thank you so much :D

[@m.caeben2578]

Quick and to the point. I had my solution of B in terms of sinh and cosh, obfuscating the interpretation of lambda_L. Thanks for the whole work and mentioning the pros and caveats of the derivation. Have a good one,

[@PrettyMuchPhysics]

Thanks for the nice comment!

[@ShreyaAnish-p6t]

Thank you sooooo much!!! I am amazed how you taught me so much in 4 minutes!!!

[@quahntasy]

*Another great explanation* Loved it again

[@PrettyMuchPhysics]

Thank you :)

[@Higgsinophysics]

Loved that example in the end - was really interesting :D

[@PrettyMuchPhysics]

I love that just by assuming some "extended" version of Ohm's law, you suddenly get the Meissner effect for free :D

[@Rysdan9]

Yay Superconductivity. Thank you.

[@PrettyMuchPhysics]

Glad you liked it :D

[@zakirreshi6737]

And thanks for uploading

:D

[@x000s2]

More superconductivity, please!

[@PrettyMuchPhysics]

Maybe!

[@bouhababrahim2292]

Nicely done tank you

[@PrettyMuchPhysics]

Thanks! :)

Is Ns a material dependent term?

[@dio_del_tempo]

i have a question, if we cannot assume a uniform electric field, why do we get the exact same result as the one we get by using quantum mechanics? Is it because the classical approach only involves the uniform electric field while the quantum approach involves both uniform and non uniform electric fields (which is a better approach since we involve all the cases), but they turn out to give the same results, even so we say the first approach isn't very correct since we only consider uniform even if it gives the same result, so eventually we say both approaches give the same result but the quantum one is better since the logic behind is more rigorous, is my understanding correct, if not please fix me

[@alijassim7015]

Someone ignorant like me, just from the name of the equations thought the physicist to be English. Well, what a surprise! XD

[@PrettyMuchPhysics]

Right?? Who would’ve thought?

[@RichardKCollins]

You rushed at the end and missed the most important insights and applications. SLOW DOWN and think while you are talking.
