Confinement in (1 + 1) dimensions: a holographic perspective from I-branes
Carlos Núñez, Marcelo Oyarzo, Ricardo Stuardo
Abstract
A bstract In this paper we holographically study the strongly coupled dynamics of the field theory on I-branes (D5 branes intersecting on a line). In this regime, the field theory becomes (2 + 1) dimensional with 16 supercharges. The dual background has an IR singularity. We resolve this singularity by compactifiying the theory on a circle, preserving 4 supercharges. We study various aspects: confinement, symmetry breaking, Entanglement Entropy, etc. We also discuss a black membrane solution and make some comments on the string σ -model on our backgrounds.
