$S^2 \times S^1$上Dirac场的诱导宇称奇有效action

Induced parity-odd effective action for a Dirac field on $S^2 \times S^1$

C. D. Fosco, F. A. Schaposnik

摘要:

我们计算了在$S^2 \times S^1$流形上,与外部阿贝尔规范场最小耦合的大质量狄拉克费米子的有效作用量的宇称奇部分。我们对一类特殊的规范场组态进行了研究,这类组态特别适合于研究时空几何所允许的大规范场组态下费米子行列式的行为。

英文摘要:

We evaluate the parity-odd part of the effective action due to massive Dirac fermions on a $S^2 \times S^1$ manifold, minimally coupled to an external Abelian gauge field. We do that for a special class of gauge-field configurations, which is specially suitable to the study of the behaviour of the fermionic determinant under large gauge field configurations, which are allowed by the space-time geometry.
