TL;DR

This paper studies the vacuum-induced bosonic current in a conical spacetime with magnetic flux, considering a Hořava-Lifshitz Lorentz violation scenario, and analyzes boundary effects and asymptotic behaviors.

It provides analytical expressions for vacuum bosonic currents in a conical spacetime with boundary under Lorentz violation, including boundary-induced effects and asymptotic analysis.

Findings

Boundary-induced currents depend on magnetic flux and boundary conditions.

Asymptotic behaviors of currents are characterized in specific limits.

Analytical formulas for vacuum currents are derived in the Lorentz-violating scenario.

Abstract

We investigate the vacuum expectation value of bosonic current induced by a magnetic flux in a $(2+1)-$dimensional conical spacetime in the presence of a circular boundary, in a Ho{\v{r}}ava-Lifshitz Lorentz violation symmetry scenario. We assume that the circular boundary is concentric with magnetic flux, and the massive scalar quantum field obeys the Robin boundary condition on the boundary. In order to develop this analysis, we calculate the positive frequency Wightman functions for both regions, inside and outside the boundary. Using these functions, we obtain analytical expressions for the vacuum expectation bosonic currents. As we will see, these functions are presented in the form of the sum of boundary-free and boundary-induced parts. As to the boundary-induced currents, some asymptotic behaviors are investigated for specific limiting cases; moreover, in order to provide a better understanding about the behavior of the currents, some plots are given.
