Interface evolution in the two-dimensional quantum Ising model
Georgios Kampanis, Marianna Sorba, Gesualdo Delfino
We consider the unitary time evolution of an interface in the regime of spontaneously broken symmetry of the two-dimensional quantum Ising model. The interface is induced by an ini…
Quantum quenches with long range interactions
Marianna Sorba, Nicolò Defenu, Gesualdo Delfino
We extend the theory of quantum quenches to the case of -dimensional homogeneous systems with long range interactions. This is achieved treating the long range interactions as s…
On unitary time evolution out of equilibrium
Gesualdo Delfino, Marianna Sorba
We consider -dimensional quantum systems which for positive times evolve with a time-independent Hamiltonian in a nonequilibrium state that we keep generic in order to account f…
Mass of quantum topological excitations and order parameter finite size dependence
Gesualdo Delfino, Marianna Sorba
We consider the spontaneously broken regime of the vector model in space-time dimensions, with boundary conditions enforcing the presence of a topological defect lin…
Quantum quenches from an excited state
Gesualdo Delfino, Marianna Sorba
Determining the role of initial conditions in the late time evolution is a key issue for the theory of nonequilibrium dynamics of isolated quantum systems. Here we extend the theor…
Space of initial conditions and universality in nonequilibrium quantum dynamics
Gesualdo Delfino, Marianna Sorba
We study analytically the role of initial conditions in nonequilibrium quantum dynamics considering the one-dimensional ferromagnets in the regime of spontaneously broken symmetry.…
Persistent oscillations after quantum quenches in dimensions
Gesualdo Delfino, Marianna Sorba
We obtain analytical results for the time evolution of local observables in systems undergoing quantum quenches in spatial dimensions. For homogeneous systems we show that osci…
Interface in presence of a wall. Results from field theory
Gesualdo Delfino, Marianna Sorba, Alessio Squarcini
We consider three-dimensional statistical systems at phase coexistence in the half-volume with boundary conditions leading to the presence of an interface. Working slightly below t…
