摘要

考虑标量凝聚-费米子混合物的相对论作用，其中标量玻色子和费米子场都耦合到U(1)规范场。规范场的动力学由麦克斯韦项和带常系数θ的洛伦兹不变量E·B项的线性组合控制。利用粒子-弦二象性得到了描述费米子-费米子相互作用和费米子-涡旋管相互作用的有效作用，并发现θ项对费米子与涡旋的相互作用有显著影响。我们还进行了一次降维，以显示与流动费米子有关的θ依赖通量。

Fermion-vortex interactions in axion electrodynamics

A relativistic action for scalar condensate-fermion mixture is considered where both the scalar boson and the fermion fields are coupled to a

U (1)

gauge field. The dynamics of the gauge field is governed by a linear combination of the Maxwell term, and the Lorentz invariant

E⋅B

term with a constant coefficient

θ

. We obtain an effective action describing an emergent fermion–fermion interaction and fermion–vortex tube interaction by using the particle-string duality, and find that the

θ

term can significantly affect the interaction of fermions and vortices. We also perform a dimensional reduction to show a

θ

dependent flux attachment to the itinerant fermions.
