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…
Entanglement, combinatorics and finite-size effects in spin-chains
Bernard Nienhuis, Massimo Campostrini, Pasquale Calabrese
We carry out a systematic study of the exact block entanglement in XXZ spin-chain at Delta=-1/2. We present, the first analytic expressions for reduced density matrices of n spins…
Evolution of entanglement entropy following a quantum quench: Analytic results for the XY chain in a transverse magnetic field
Maurizio Fagotti, Pasquale Calabrese
The non-equilibrium evolution of the block entanglement entropy is investigated in the XY chain in a transverse magnetic field after the Hamiltonian parameters are suddenly changed…
Time evolution of 1D gapless models from a domain-wall initial state: SLE continued?
Pasquale Calabrese, Christian Hagendorf, Pierre Le Doussal
We study the time evolution of quantum one-dimensional gapless systems evolving from initial states with a domain-wall. We generalize the path-integral imaginary time approach that…
Entanglement and correlation functions following a local quench: a conformal field theory approach
Pasquale Calabrese, John Cardy
We show that the dynamics resulting from preparing a one-dimensional quantum system in the ground state of two decoupled parts, then joined together and left to evolve unitarily wi…
Correlation functions of one-dimensional anyonic fluids
Pasquale Calabrese, Mihail Mintchev
A universal description of correlation functions of one-dimensional anyonic gapless systems in the low-momentum regime is presented. We point out a number of interesting features,…
