Electrodynamics effects in 3+1 dimensions induced by interactions in Topological Insulators

TL;DR

This paper explores how specific interactions in 3+1 dimensional topological insulators can induce electrodynamics effects similar to those in higher-dimensional non-interacting topological insulators, revealing a dimensional correspondence.

Contribution

It demonstrates that certain interactions in 3+1D topological insulators produce electrodynamics responses equivalent to 4+1D non-interacting cases, highlighting a novel dimensional relationship.

Findings

Interactions induce 3+1D electrodynamics effects

Response matches 4+1D non-interacting topological insulators

Establishes a dimensional correspondence in topological phases

Abstract

We investigate the effect of interactions in the Topological Insulator in 3+1 dimensions. We show that for a particular type of interactions, the Electrodynamics response is equivalent to the response of non-interacting Topological Insulator in 4+1 dimensions.
