Roles of electric field/time-dependent Wilson line in toroidal compactification with or without magnetic fluxes
Abstract We discuss the effects of electric fields along compact directions within (supersymmetric) gauge theory in ℝ 1 , 3 × T 2 × T 2 × T 2 $$ {\mathbb{R}}^{1,3}\times {\mathbbm{T}}^2\left(\times {\mathbbm{T}}^2\times {\mathbbm{T}}^2\right) $$ . The electric field along compact directions is equiv...

| description | Abstract We discuss the effects of electric fields along compact directions within (supersymmetric) gauge theory in ℝ 1 , 3 × T 2 × T 2 × T 2 $$ {\mathbb{R}}^{1,3}\times {\mathbbm{T}}^2\left(\times {\mathbbm{T}}^2\times {\mathbbm{T}}^2\right) $$ . The electric field along compact directions is equivalent to time-dependent homogeneous configuration of Wilson line moduli, which would be relevant to physics in the early universe. In particular, we consider models with and without background magnetic fluxes, which lead to completely different effects of the electric field due to the difference in the Kaluza-Klein (KK) level structure. We show that, in the case without magnetic fluxes, the deceleration of KK momenta may cause non-perturbative KK particle production dubbed as the KK Schwinger effect, whereas in the case with magnetic flux such KK particle production does not take place but flavor structure of low energy effective theory may be affected. |
