Interfacial tension and wall energy of a Bose-Einstein condensate binary mixture: triple-parabola approximation

Zehui Deng, Bert Van Schaeybroeck, Chang-You Lin +2

Accurate and useful analytic approximations are developed for order parameter profiles and interfacial tensions of phase-separated binary mixtures of Bose-Einstein condensates. The…

Effective Hamiltonians, prethermalization and slow energy absorption in periodically driven many-body systems

D. A. Abanin, W. De Roeck, W. W. Ho +1

We establish some general dynamical properties of lattice many-body systems that are subject to a high-frequency periodic driving. We prove that such systems have a quasi-conserved…

Role of trapping and crowding as sources of negative differential mobility

Marco Baiesi, Attilio L. Stella, Carlo Vanderzande

Increasing the crowding in an environment does not necessarily trigger negative differential mobility of strongly pushed particles. Moreover, the choice of the model, in particular…

Exponentially slow heating in periodically driven many-body systems

Dmitry Abanin, Wojciech De Roeck, François Huveneers

We derive general bounds on the linear response energy absorption rates of periodically driven many-body systems of spins or fermions on a lattice. We show that for systems with lo…

The Physicist's Companion to Current Fluctuations: One-Dimensional Bulk-Driven Lattice Gases

Alexandre Lazarescu

One of the main features of statistical systems out of equilibrium is the currents they exhibit in their stationary state: microscopic currents of probability between configuration…

Generalized maximum entropy approach to quasi-stationary states in long range systems

Gabriele Martelloni, Gianluca Martelloni, Pierre de Buyl +1

Systems with long-range interactions display a short-time relaxation towards Quasi Stationary States (QSS) whose lifetime increases with the system size. In the paradigmatic Hamilt…

Nonequilibrium Response and Frenesy

Urna Basu, Christian Maes

We present examples of how time-symmetric kinetic factors contribute to the response either in nonlinear order around equilibrium or in linear order around nonequilibrium. The phen…

Statistical forces from close--to--equilibrium media

Urna Basu, Christian Maes, Karel Netočný

We discuss the physical meaning and significance of statistical forces on quasi-static probes in first order around detailed balance for driven media. Exploiting the quasi-static e…

How statistical forces depend on thermodynamics and kinetics of driven media

Urna Basu, Christian Maes, Karel Netocny

We study the statistical force of a nonequilibrium environment on a quasi-static probe. In the linear regime the isothermal work on the probe equals the excess work for the medium…

Driven-dissipative ising model: mean field solution

Garry Goldstein, Camille Aron, Claudio Chamon

We study the fate of the Ising model and its universal properties when driven by a rapid periodic drive and weakly coupled to a bath at equilibrium. The far from equilibrium steady…

Static interfacial properties of Bose-Einstein condensate mixtures

Joseph O. Indekeu, Chang-You Lin, Nguyen Van Thu +2

Interfacial profiles and interfacial tensions of phase-separated binary mixtures of Bose-Einstein condensates are studied theoretically. The two condensates are characterized by th…
