Abstract

This work presents a study of the entanglement entropy (EE) in a class of four-dimensional N = 1 linear quiver SCFTs deformed by the presence of a VEV. We review the holographic backgrounds dual to these theories, and calculate the EE for different Ryu-Takayanagi embeddings. We allow the embeddings...
