DOI: 10.1073/pnas.2303231120

Abstract: Short-time dynamics of superfluids far from equilibrium remains largely unknown, despite its importance for key processes in these systems. Here, we describe a method for locally perturbing the density of superfluid helium via the excitation… read more here.

DOI: 10.1103/physrevb.98.235127

Abstract: We study the nonequilibrium dynamics in the pump-probe spectroscopy of excitonic insulators using the spinless two-orbital model with phonon degrees of freedom in the time-dependent mean-field approximation. We introduce the pulse light as a time-dependent… read more here.

DOI: 10.1103/physreve.100.013002

Abstract: Marginally stable systems exhibit rich critical mechanical behavior. Such isostatic assemblies can be actively driven, but it is unclear how their critical nature affects their nonequilibrium dynamics. Here, we study the influence of isostaticity on… read more here.

DOI: 10.1103/physreve.106.014137

Abstract: The same system can exhibit a completely different dynamical behavior when it evolves in equilibrium conditions or when it is driven out-of-equilibrium by, e.g., connecting some of its components to heat baths kept at different… read more here.

DOI: 10.1103/physreve.106.054311

Abstract: We investigate the nonequilibrium dynamics of a three-state kinetic exchange model of opinion formation, where switches between extreme states are possible, depending on the value of a parameter q. The mean field dynamical equations are derived… read more here.

DOI: 10.1103/physrevlett.121.170501

Abstract: We present a hybrid quantum-classical algorithm for the time evolution of out-of-equilibrium thermal states. The method depends on classically computing a sparse approximation to the density matrix and, then, time-evolving each matrix element via the… read more here.

DOI: 10.1103/physrevlett.123.113002

Abstract: We present an experimental study on nonequilibrium dynamics of a spinor condensate after it is quenched across a superfluid to Mott insulator (MI) phase transition in cubic lattices. Intricate dynamics consisting of spin-mixing oscillations at… read more here.

recommendations! Published in 2020 at "Physical review letters"

DOI: 10.1103/physrevlett.124.031601

Abstract: By holographic duality, we identify a novel dynamical phase transition which results from the temperature dependence of nonequilibrium dynamics of dark solitons in a superfluid. For a nonequilibrium superfluid system with an initial density of… read more here.

DOI: 10.1103/physrevlett.127.200603

Abstract: We propose a new field theoretic method for calculating Renyi entropy of a subsystem of many interacting bosons without using replica methods. This method is applicable to dynamics of both open and closed quantum systems… read more here.
