Семинар «Теория адронного вещества при экстремальных условиях»

В понедельник, 11 апреля 2016 г. в 16:00, в конференц-зале им.Блохинцева ЛТФ (4-й этаж) состоится семинар «Competition and duality correspondence between chiral and superconducting channels in (2+1)-dimensional four-fermion models».

Докладчик: Дитмар Эберт (Берлинский университет имени Гумбольдта)

Аннотация:

I will explain the duality correspondence between fermion-antifermion and di-fermion interaction channels as established in two (2+1)-dimensional Gross-Neveu type models with a fermion number chemical potential μ and a chiral chemical potential μ_5. The role and influence of this property on the phase structure of the models are investigated. In particular, it is shown that the chemical potential μ_5 promotes the appearance of dynamical chiral symmetry breaking, whereas the chemical potential μ contributes to the emergence of superconductivity. arXiv:1603.00357
