Adiabatic Expansion Fermion Gases Photon quasistatic

AI Thread Summary

The discussion revolves around demonstrating that PV^Y remains constant during adiabatic, quasistatic expansion for both photon gases and fully degenerate fermion gases at absolute zero temperature. Participants are seeking guidance on how to derive the value of Y for photon gases and the conditions for fermion gases. The conversation highlights the need for relevant equations and concepts from lecture notes to solve these problems. There is an emphasis on understanding the thermodynamic principles underlying these gas behaviors. Assistance is requested to clarify these concepts and provide solutions.

Do you have any ideas whatsoever? You must have something in your lecture notes...

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
