"Orbifold equivalence in large-N QCD with finite baryon chemical potential and the sign problem"

Presented by Masanori Hanada, University of Washington, Seattle

Friday, April 1, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

We point out that large-N_c QCD in the 't Hooft limit is equivalent to SO(2*N_c) Yang-Mills theory with fundamental fermions. In the latter, notorious "sign problem" is absent even with finite baryon chemical potential, and hence the Monte-Carlo simulation is applicable. We also show the same idea can be applied in related models
-- chiral random matrix theory (RMT) and holographic models. We explain nice old results like the exactness of the phase quenching in RMT in a certain parameter region is naturally understood and is generalized from the point of view of the equivalence.

This talk is based on works with A. Cherman and D. Robles-Llana (Phys. Rev. Lett. 106, 091603), with N. Yamamoto (in preparation) and with C. Hoyos, A. Karch and L. Yaffe (in preparation).
