Wednesday, November 2nd 2016
4:30 pm:
CM Journal Club in PAN 110
Speaker: Ruiqi Xing
Subject: Fermi liquid and Luttinger liquid

Following Xiaoyu's talk on Fermi liquid and Non-Fermi liquid and Alberto's talk on renormalization group, I will talk about:
0. Introduction of phenomenological Landau Fermi liquid and review of RG for interacting fermions
1. Tomonaga-Luttinger liquid as a fixed point of RG flow for general 1d interacting fermions; spin-charge separation in the Luttinger model.
2. Why Fermi liquid is extremely robust-Landau Fermi liquid as a fixed point of RG flow for 2d and 3d interacting fermions.
3. Kohn-Luttinger effect and BCS in the language of RG(briefly).

The weekly calendar is also available via subscription to the physics-announce mailing list, and by RSS feed.
