Quantum Quench in the Transverse Field Ising Chain
Pasquale Calabrese, Fabian H. L. Essler, Maurizio Fagotti
We consider the time evolution of observables in the transverse field Ising chain (TFIC) after a sudden quench of the magnetic field. We provide exact analytical results for the as…
Quantum quenches from integrability: the fermionic pairing model
Alexandre Faribault, Pasquale Calabrese, Jean-Sebastien Caux
Understanding the non-equilibrium dynamics of extended quantum systems after the trigger of a sudden, global perturbation (quench) represents a daunting challenge, especially in th…
Junctions of anyonic Luttinger wires
Brando Bellazzini, Pasquale Calabrese, Mihail Mintchev
We present an extended study of anyonic Luttinger liquids wires jointing at a single point. The model on the full line is solved with bosonization and the junction of an arbitrary…
Entanglement spectrum in one-dimensional systems
Pasquale Calabrese, Alexandre Lefevre
We derive the distribution of eigenvalues of the reduced density matrix of a block of length l in a one-dimensional system in the scaling regime. The resulting "entanglement spectr…
