All I know about the differences with respect to the original version is what you can see in the picture of the back cover here.

Hi, I have notice that Ashcroft, Mermin and Wei worked at a revised edition of the original solid state physics book (here). The book, however, seems to be never available. I have also read that the reason is related to some disputes related to copyright. Do you have any further information...

I think this is what you are looking for: https://en.wikipedia.org/wiki/Paschen%27s_law

You are right! I read it so many times but I missed that. Indeed, since the overall system is at equilibrium, it makes sense that the two "subsystems" have the same values for the intensive variables. Kardar's book is very dense of information and I find it hard to follow sometimes... Thank you...

Hi Hill, thank you for your reply. I understand your point: \delta T_A = \frac{\partial f}{\partial E}\bigg\rvert_{T_A} \delta E_A and \delta T_B = \frac{\partial f}{\partial E}\bigg\rvert_{T_B} \delta E_B . However, since the two subsystems are not necessarily equal, even though \delta...

I am watching Kardar's Statistical Mechanics course in my spare time and I am struggling to understand a mathematical detail in the proof of the thermodynamic stability condition. See Eq. I.62 here. The author considers a homogeneous system at equilibrium with intensive and extensive variables...

Hi Hill, thank you for your reply. It makes sense now.

Hi all, recently I started following the MIT course "Statistical Mechanics I: Statistical Mechanics Of Particles" by MIT (here). In the second lesson Prof. Kardar introduces the concept of thermodynamic temperature analyzing the behavior of two Carnot engines that share a thermal reservour at...

Thank you very much, I'll take a look to all of them!

Thank you vanhees71. I know there are tons of solid state physics book published by Springer; I was looking for a recommendation for a particularly valid one. Thank you anyway!

I have the opportunity to get a Springer book for free, provided that it is cheaper than 200$. I am considering an introductory one about Solid State Physics, but I have never heard about a valid one from Springer (I know about Kittel, Ashcroft and Simon only). Do you have any suggestion? Thank...

Thank you both of you for your replies. I understand it is a matter to average the contribution of each elemental charge on the sphere surface and then sum all of them, but I am not able to go through all the calculations. For that reason, I was thinking to apply the result that I mentioned in...

A known result is that the average field inside a sphere due to all the charges inside the sphere itself is proportional to the dipole momentum of the charge distribution (see, for example, here). I wonder whether the same result can be applied in the case of a spherical shell of non-uniform...

Form the boundary conditions I can write \Phi_m=(\exp(\lambda_m z)+B_m \exp(-\lambda_m z) )C_m F_m(r) where ##F_m## is a function independent from ##L## and \begin{cases} B_m=\frac{(K_{Bm}/K_{Pm}) \exp(\lambda_m L)-1}{1- (K_{Bm}/K_{Pm}) \exp(-\lambda_m L)} \\ C_m=\frac{K_{Pm}-K_{Bm}...

Thank you!
