Generalised hydrodynamics with dephasing noise
Alvise Bastianello, Jacopo De Nardis, Andrea De Luca
We consider the out-of-equilibrium dynamics of an interacting integrable system in the presence of an external dephasing noise. In the limit of large spatial correlation of the noi…
Exact out-of-equilibrium steady states in the semiclassical limit of the interacting Bose gas
Giuseppe Del Vecchio Del Vecchio, Alvise Bastianello, Andrea De Luca +1
We study the out-of-equilibrium properties of a classical integrable non-relativistic theory, with a time evolution initially prepared with a finite energy density in the thermodyn…
Domain-wall melting in the spin- XXZ spin chain: emergent Luttinger liquid with fractal quasi-particle charge
Mario Collura, Andrea De Luca, Pasquale Calabrese +1
In spin chains with local unitary evolution preserving the magnetization , the domain-wall state $\left| \dots \uparrow \uparrow \uparrow \uparrow \uparrow \downarrow \d…
Entanglement front generated by an impurity travelling in an isolated many-body quantum system
Andrea De Luca, Alvise Bastianello
We investigate the effect on the entanglement dynamics of an impurity moving at constant velocity in a closed quantum system. We focus on one-dimensional strongly-correlated lattic…
Spectral statistics and many-body quantum chaos with conserved charge
Aaron J. Friedman, Amos Chan, Andrea De Luca +1
We investigate spectral statistics in spatially extended, chaotic many-body quantum systems with a conserved charge. We compute the spectral form factor analytically for a m…
Domain wall problem in the quantum XXZ chain and semiclassical behavior close to the isotropic point
Grégoire Misguich, Nicolas Pavloff, Vincent Pasquier
We study the dynamics of a spin-1/2 XXZ chain which is initially prepared in a domain-wall state. We compare the results of time-dependent Density Matrix Renormalization Group simu…
Ballistic transport and boundary resistances in inhomogeneous quantum spin chains
Alberto Biella, Mario Collura, Davide Rossini +2
Transport phenomena are central to physics, and transport in the many-body and fully-quantum regime is attracting an increasing amount of attention. It has been recently revealed t…
Integrability-protected adiabatic reversibility in quantum spin chains
A. Bastianello, A. De Luca
We consider the out-of-equilibrium dynamics of the Heisenberg anisotropic quantum spin-- chain threaded by a time-dependent magnetic flux. In the spirit of the recently develo…
Stability and Phase Transition of Skyrmion Crystals Generated by Dzyaloshinskii-Moriya Interaction
Sahbi El Hog, Aurélien Bailly-Reyre, H. T. Diep
We generate a crystal of skyrmions in two dimensions using a Heisenberg Hamiltonian including the ferromagnetic interaction J, the Dzyaloshinskii-Moriya interaction D, and an appli…
Partial phase transition and quantum effects in helimagnetic films under an applied magnetic field
Sahbi El-Hog, Hung T. Diep
We study the phase transition in a helimagnetic film with Heisenberg spins under an applied magnetic field in the c direction perpendicular to the film. The helical structure is du…

We study in this paper magnetic properties of a system of quantum Heisenberg spins interacting with each other via a ferromagnetic exchange interaction J and an in-plane Dzyaloshin…

Virgile Bocchetti, Hung T. Diep
We study the melting transition in crystals of rare gas Ar, Xe, and Kr by the use of extensive Monte Carlo simulations with the Lennard-Jones potential. The parameters of this pote…
Re-orientation Transition in Molecular Thin Films: Potts Model with Dipolar Interaction
Danh-Tai Hoang, Maciej Kasperski, Henryk Puszkarski +1
We study the low-temperature behavior and the phase transition of a thin film by Monte Carlo simulation. The thin film has a simple cubic lattice structure where each site is occup…
