An early result of algebraic quantum field theory is that the algebra of any subregion in a
QFT is a von Neumann factor of type III $ _ {1} $, in which entropy cannot be well-defined …

A bstract We develop a systematic approach to compute the subsystem trace distances and
relative entropies for subsystem reduced density matrices associated to excited states in …

A bstract We introduce and study generalized Rényi entropies defined through the traces of
products of Tr B (| Ψ i⟩⟨ Ψ j|) where∣ Ψ i⟩ are eigenstates of a two-dimensional conformal …

Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum
field theory as a partial trace is necessarily a challenging task. Nevertheless, such …

Quantifying entanglement properties of mixed states in quantum field theory via
entanglement of purification and reflected entropy is a new and challenging subject. In this …

A bstract We study the entanglement entropy and the modular Hamiltonian of slightly excited
states reduced to a ball shaped region in generic conformal field theories. We set up a …

Conformal field theories in curved backgrounds have been used to describe
inhomogeneous one-dimensional systems, such as quantum gases in trapping potentials …

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 We study the relative entanglement entropies of one interval between excited
states of a 1+ 1 dimensional conformal field theory (CFT). To compute the relative entropy S …

A bstract Quantum corrections to the entanglement entropy of matter fields interacting with
dynamical gravity have proven to be very important in the study of the black hole information …
