Entanglement Entropy for Relevant and Geometric Perturbations
Vladimir Rosenhaus, Michael Smolkin
We continue the study of entanglement entropy for a QFT through a perturbative expansion of the path integral definition of the reduced density matrix. The universal entanglement e…
Twist operators in higher dimensions
Ling-Yan Hung, Robert C. Myers, Michael Smolkin
We study twist operators in higher dimensional CFT's. In particular, we express their conformal dimension in terms of the energy density for the CFT in a particular thermal ensembl…
Entanglement entropy, planar surfaces, and spectral functions
Vladimir Rosenhaus, Michael Smolkin
We consider the universal part of entanglement entropy across a plane in flat space for a QFT, giving a non-perturbative expression in terms of a spectral function. We study the ch…
Entanglement Entropy Flow and the Ward Identity
Vladimir Rosenhaus, Michael Smolkin
We derive differential equations for the flow of entanglement entropy as a function of the metric and the couplings of the theory. The variation of the universal part of entangleme…
Correlation functions on conical defects
Michael Smolkin, Sergey N. Solodukhin
We explore the new technique developed recently in \cite{Rosenhaus:2014woa} and suggest a correspondence between the -point correlation functions on spacetime with conical defec…
Entanglement Entropy: A Perturbative Calculation
Vladimir Rosenhaus, Michael Smolkin
We provide a framework for a perturbative evaluation of the reduced density matrix. The method is based on a path integral in the analytically continued spacetime. It suggests an a…
