Parity effects in the scaling of block entanglement in gapless spin chains

Pasquale Calabrese, Massimo Campostrini, Fabian Essler +1

We consider the Renyi alpha-entropies for Luttinger liquids (LL). For large block lengths l these are known to grow like ln l. We show that there are subleading terms that oscillat…

Entanglement entropy of excited states

Vincenzo Alba, Maurizio Fagotti, Pasquale Calabrese

We study the entanglement entropy of a block of contiguous spins in excited states of spin chains. We consider the XY model in a transverse field and the XXZ Heisenberg spin-chain.…

Entanglement entropy of two disjoint blocks in critical Ising models

Vincenzo Alba, Luca Tagliacozzo, Pasquale Calabrese

We study the scaling of the Renyi and entanglement entropy of two disjoint blocks of critical Ising models, as function of their sizes and separations. We present analytic results…

Trap-size scaling in confined particle systems at quantum transitions

Massimo Campostrini, Ettore Vicari

We develop a trap-size scaling theory for trapped particle systems at quantum transitions. As a theoretical laboratory, we consider a quantum XY chain in an external transverse fie…

Entanglement entropy and conformal field theory

Pasquale Calabrese, John Cardy

We review the conformal field theory approach to entanglement entropy. We show how to apply these methods to the calculation of the entanglement entropy of a single interval, and t…

Critical behavior and scaling in trapped systems

Massimo Campostrini, Ettore Vicari

We study the scaling properties of critical particle systems confined by a potential. Using renormalization-group arguments, we show that their critical behavior can be cast in the…

Quantum Quench from a Thermal Initial State

Spyros Sotiriadis, Pasquale Calabrese, John Cardy

We consider a quantum quench in a system of free bosons, starting from a thermal initial state. As in the case where the system is initially in the ground state, any finite subsyst…
