A bstract We present a thorough analysis of the entanglement entropies related to different
symmetry sectors of free quantum field theories (QFT) with an internal U (1) symmetry. We …

The eigenstate thermalization hypothesis (ETH) provides a way to understand how an
isolated quantum mechanical system can be approximated by a thermal density matrix. We …

Infinite-dimensional conformal symmetry in two dimensions leads to integrability of 2D
conformal field theories (CFTs) by giving rise to an infinite tower of local conserved quantum …

A bstract We discuss partition function of 2d CFTs decorated by higher qKdV charges in the
thermodynamic limit when the size of the spatial circle goes to infinity. In this limit the saddle …

We develop a systematic method to calculate the trace distance between two reduced
density matrices in 1+ 1 dimensional quantum field theories. The approach exploits the path …

A bstract We report on a systematic replica approach to calculate the subsystem trace
distance for a quantum field theory. This method has been recently introduced in [J. Zhang …

A bstract In this paper, we study the holographic descriptions of the conformal block of heavy
operators in two-dimensional large c conformal field theory. We consider the case that the …

A bstract We calculate various quantities that characterize the dissimilarity of reduced
density matrices for a short interval of length ℓ in a two-dimensional (2D) large central …

A bstract We study the excited state Rényi entropy and subsystem Schatten distance in the
two-dimensional free massless non-compact bosonic field theory, which is a conformal field …

A bstract We evaluate one-interval Rényi entropy and entanglement entropy for the excited
states of two-dimensional conformal field theory (CFT) on a cylinder, and examine their …
