Evolution of entanglement entropy in the D1-D5 brane system
Evolution of entanglement entropy in the D1-D5 brane system
We calculate the evolution of the geometric entanglement entropy following a local quench in the D1-D5 conformal field theory, a two-dimensional theory that describes a particular bound state of D1 and D5 branes. The quench corresponds to a localized insertion of the exactly marginal operator that deforms the field theory …
