磁场中非微扰物理

Nonperturbative Physics in a Magnetic Field

Vivian de la Incera

摘要:

非微扰量子场论在研究某些物理条件下费米子凝聚现象中起着重要的作用。我们所熟悉的电超导现象、高密度夸克物质的色超导现象以及低能有效手征理论的手征对称性破缺都是这类例子。人们常常对这些系统在外部磁场存在下的行为感兴趣。在这次演讲中,我将概述外部磁场对费米子-费米子或费米子-反费米子凝聚理论的影响。

英文摘要:

Non-Perturbative Quantum Field Theory has played an important role in the study of phenomena where a fermion condensate can appear under certain physical conditions. The familiar phenomenon of electric superconductivity, the color superconductivity of very dense quark matter, and the chiral symmetry breaking of low energy effective chiral theories are all examples of that sort. Often one is interested in the behavior of these systems in the presence of an external magnetic field. In this talk I will outline the effects of an external magnetic field on theories with either fermion-fermion or fermion-antifermion condensates.
