Band structure and fermi liquid

Click For Summary
Band structure calculations and Hartree-Fock methods can be integrated within the framework of Fermi liquid theory, where quasiparticles are represented as one-electron states. The Hartree-Fock method effectively determines the ground-state wave function and energy of quantum many-body systems, making it applicable to Fermi liquids. A referenced article discusses a Hartree-Fock-BCS method specifically for electron liquids, highlighting its relevance. This integration suggests a deeper understanding of electron interactions in condensed matter physics. Overall, the discussion emphasizes the compatibility of these theoretical approaches in describing electron behavior.

Hi everyone!

I wanted to ask if in your opinion is it right to say that band structure calculations (and hartree fock calculations) could live in a framework of the fermi liquid theory where quasiparticles are one-electron states (which could be or not could be the case)...

Hi tirrel,

As the Hartree-Fock method is a method for the determination of the ground-state wave function and ground-state energy of a quantum many-body system, basically it is suitable for calculating the ground-state wave-function of a Fermi-liquid.

Take a look at this article: http://www.physics.utoronto.ca/~qocmp/PRB34515.pdf" . They show a Hartree-Fock-BCS method for the electron-liquid.

Thread 'Time rondeau crystals, experimental observations'

A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
