Spectrum of Modular Hamiltonian in the Vacuum and Excited States
Abstract
We study the non-zero eigenmodes for the modular Hamiltonian in the context of AdS3/CFT2. We show how to perturbatively construct zero eigenmodes for the modular Hamiltonian of the class of excited states constructed in Lashkari et al.(arxiv:1811.05052), using information about the vacuum non-zero eigen modular modes.
