High-Energy Concepts in High-T_c Superconductivity
Germán Sierra
I.M.A.F.F./C.S.I.C. and I.F.T.
High Temperature Superconductivity remains as one of the most
sounding and unsolved problems in Condensed Matter. This is
largely due to the richness and variety of the many body
phases involved: antiferromagnetism, d-wave
superconductivity, pseudogap regime, stripes. All these
phenomena seem to be intimately related but one lacks a
unified and consistent explanation. Recently there has been
several proposals for a unified explanation of the high-Tc
superconductivity which are largely inspired by Particle
Physics theories. Some examples are given by the SO(5) of
Zhang which unifies the antiferromagnetism and d-wave
superconductivity, the SO(8) of the two leg ladder, the dual
descriptions of the pseudogap region, the quantum string
model of the stripes, etc. We shall give a brief
introduction of these ideas and present some related work.
The almuerzo-seminario is
intended to be an informal seminar and an open forum for discussion.
You are wellcome to bring your own
bocata (sandwich), or coffee or tea.
Where: Modulo C-XVI, 3rd floor,
Facultad de Ciencias U.A.M., C.U. Cantoblanco, 28049-Madrid
