Condensed concepts

 I just finished preparing my undergraduate lecture on the Debye model for solids. Here are my slides . The course is a third-year course on...

Here are the slides for an undergraduate lecture I gave today. The slides also include the derivations I gave by hand on the document viewe...

 I just finished preparing my undergraduate lecture on ideal Fermi gases at zero temperature. Here are my slides.  (Note. The derivations ar...

In two weeks, I am giving two lectures about degenerate Fermi gases in a third-year undergraduate course on statistical mechanics.  The text...

 This semester, I am giving four lectures in a third-year undergraduate course on statistical mechanics. Last year, I gave a guest lecture ...

A typical undergraduate course on statistical mechanics is arguably misleading because (unintentionally) it does not tell students several i...

In 1925, Ising published his paper on the solution of the model in one dimension. An English translation is here. https://www.hs-augsburg.de...

This is ultra-condensed matter physics! In 1931,  Subrahmanyan Chandrasekhar published a seminal paper, for which he was awarded the Nobel ...

In my recent tutorial on bad metals at IISER Pune a student asked me a basic question that I could not answer: "Why is the degenerate ...

I used to find the concept of the chemical potential rather confusing. Hence, it is not surprising that students struggle too. I could say...

I have posted before that I think it is very important in teaching to present students with comparisons of theory with actual experimental ...

An incredibly important and useful equation is the Sackur-Tetrode equation which gives the absolute entropy of an ideal gas and shows how -...
