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…
Armchair graphene nanoribbons: PT-symmetry breaking and exceptional points without dissipation
Maurizio Fagotti, Claudio Bonati, Demetrio Logoteta +2
We consider a single layer graphene nanoribbon with armchair edges in a longitudinally constant external potential and point out that its transport properties can be described by m…
Universal parity effects in the entanglement entropy of XX chains with open boundary conditions
Maurizio Fagotti, Pasquale Calabrese
We consider the Renyi entanglement entropies in the one-dimensional XX spin-chains with open boundary conditions in the presence of a magnetic field. In the case of a semi-infinite…
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…
