We consider the logarithmic negativity of a finite interval embedded in an infinite one
dimensional system at finite temperature. We focus on conformal invariant systems and we …

In this paper, we explore properties of pseudoentropy in quantum field theories and spin
systems from several approaches. pseudoentropy is a generalization of entanglement …

Pseudo-entropy is an interesting quantity with a simple gravity dual, which generalizes
entanglement entropy such that it depends on both an initial and a final state. Here we …

A bstract In this work we study the time evolutions of (Renyi) entanglement entropy of locally
excited states in two dimensional conformal field theories (CFTs) at finite temperature. We …

A bstract We mainly study the Rényi entropy and entanglement entropy of the states locally
excited by the descendent operators in two dimensional conformal field theories (CFTs). In …

In this work we consider the time evolution of charged Rényi entanglement entropies after
exciting the vacuum with local fermionic operators. In order to explore the information …

We show that in 1+ 1 dimensional conformal field theories, exciting a state with a local
operator increases the Rényi entanglement entropies by a constant which is the same for …

A bstract We study the time evolution of Renyi entanglement entropy for locally excited
states in two dimensional large central charge CFTs. It generically shows a logarithmical …

The Rényi entanglement entropy (REE) of the states excited by local operators in two-
dimensional irrational conformal field theories (CFTs), especially in Liouville field theory …

A bstract In this work, we study the universal behaviors in the mutual information of two
disjoint spheres in a conformal field theory (CFT). By using the operator product expansion …
