Quantum quenches as classical critical films
Andrea Gambassi, Pasquale Calabrese
We study the unitary time evolution of the order parameter of a quantum system after a sudden quench in the parameter driving the transition. By mapping the dynamics onto the imagi…
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…
Universal corrections to scaling for block entanglement in spin-1/2 XX chains
Pasquale Calabrese, Fabian H. L. Essler
We consider the Rényi entropies in the one dimensional spin-1/2 Heisenberg XX chain in a magnetic field. The case n=1 corresponds to the von Neumann ``entanglement'' en…
Scaling of bipartite entanglement in one-dimensional lattice systems with a trapping potential
Massimo Campostrini, Ettore Vicari
We study the effects of a power-law trapping potential on the scaling behaviour of the entanglement at the quantum critical point of one-dimensional (1D) lattice particle systems.…
Quantum critical behavior and trap-size scaling of trapped bosons in a one-dimensional optical lattice
Massimo Campostrini, Ettore Vicari
We study the quantum (zero-temperature) critical behaviors of confined particle systems described by the one-dimensional (1D) Bose-Hubbard model in the presence of a confining pote…
Entanglement entropy of two disjoint blocks in XY chains
Maurizio Fagotti, Pasquale Calabrese
We study the Renyi entanglement entropies of two disjoint intervals in XY chains. We exploit the exact solution of the model in terms of free Majorana fermions and we show how to c…
Conservation laws for strings in the Abelian Sandpile Model
Sergio Caracciolo, Guglielmo Paoletti, Andrea Sportiello
The Abelian Sandpile generates complex and beautiful patterns and seems to display allometry. On the plane, beyond patches, patterns periodic in both dimensions, we remark the pres…
