Schrödinger Spacetimes with Screen and Reduced Entanglement
arXiv:1309.7908
Abstract
We study a particular class of type II string vacua which become Schrödinger like spacetime in the IR region but are conformally AdS in asymptotic UV region. These solutions are found to possess some unique properties such as the presence of a spacetime `screen'. This Schrödinger (spacetime) screen is however very different from a black-hole horizon. It requires the presence of finite chemical potential and a negative charge density in the Schrödinger CFT. We find that these vacua give rise to reduced entanglement entropy as compared to Lifshitz-AdS counterpart, perhaps due to the screening effects.
