Shell-Filling Effect in the Entanglement Entropies of Spinful Fermions
Fabian H. L. Essler, Andreas M. Läuchli, Pasquale Calabrese
We consider the von Neumann and Rényi entropies of the one dimensional quarter-filled Hubbard model. We observe that for periodic boundary conditions the entropies exhibit an unexp…
Dynamical Correlations after a Quantum Quench
Fabian H. L. Essler, Stefano Evangelisti, Maurizio Fagotti
In many integrable models static (equal time) correlation functions of local observables after a quantum quench relax to stationary values, which are described by a generalized Gib…
Quantum Quench in the Transverse Field Ising Chain II: Stationary State Properties
Pasquale Calabrese, Fabian H. L. Essler, Maurizio Fagotti
We consider the stationary state properties of the reduced density matrix as well as spin-spin correlation functions after a sudden quantum quench of the magnetic field in the tran…
Dynamics in the Ising field theory after a quantum quench
Dirk Schuricht, Fabian H. L. Essler
We study the real-time dynamics of the order parameter in the Ising field theory after a quench in the fermion mass, which corresponds to a quench in the transverse field…
Quantum Quench in the Transverse Field Ising chain I: Time evolution of order parameter correlators
P. Calabrese, F. H. L. Essler, M. Fagotti
We consider the time evolution of order parameter correlation functions after a sudden quantum quench of the magnetic field in the transverse field Ising chain. Using two novel met…
Finite wave vector pairing in doped two-leg ladders
N. J. Robinson, F. H. L. Essler, E. Jeckelmann +1
We consider the effects of Umklapp processes in doped two-leg fermionic ladders. These may emerge either at special band fillings or as a result of the presence of external periodi…
