Maths HEP Lunchtime Seminars: Chemical potential and superconductivity in the D3-D5 intersection

Presented by Ed Threlfall, Durham University

27 November 2009 13:00 in CM221

Probe D5 branes in AdS and AdS-Schwarzschild gravity backgrounds are
discussed as a possible dual description of a strongly-coupled 2+1
dimensional condensed matter system. We introduce a chemical
potential through a U(1) of R-symmetry, U(1) baryon number and a U(1)
isospin symmetry. We find the appropriate D5 brane embeddings in each
case and look for the spontaneous symmetry breaking which would be
needed for the gravity dual of a 2+1 dimensional superconductor.
