Delta-Bose gas on a half-line and the KPZ equation: boundary bound states and unbinding transitions

Jacopo De Nardis, Alexandre Krajenbrink, Pierre Le Doussal +1

We revisit the Lieb-Liniger model for bosons in one dimension with attractive delta interaction in a half-space with diagonal boundary conditions. This model is…

Active velocity processes with suprathermal stationary distributions and long-time tails

Tirthankar Banerjee, Urna Basu, Christian Maes

When a particle moves through a spatially-random force field, its momentum may change at a rate which grows with its speed. Suppose moreover that a thermal bath provides friction w…

Transition Path Times in Asymmetric Barriers

Michele Caraglio, Takahiro Sakaue, Enrico Carlon

Biomolecular conformational transitions are usually modeled as barrier crossings in a free energy landscape. The transition paths connect two local free energy minima and transitio…

Landau Theory for Non-Equilibrium Steady States

Camille Aron, Claudio Chamon

We examine how systems in non-equilibrium steady states close to a continuous phase transition can still be described by a Landau potential if one forgoes the assumption of analyti…

Non-Gaussian anomalous dynamics in systems of interacting run-and-tumble particles

Stefanie Put, Jonas Berx, Carlo Vanderzande

The motion of a tagged degree of freedom can give important insight in the interactions present in a complex environment. We investigate the dynamics of a tagged particle in two no…

Nonequilibrium calorimetry

Christian Maes, Karel Netocny

We consider stationary driven systems in contact with a thermal equilibrium bath. There is a constant (Joule) heat dissipated from the steady system to the environment as long as a…

Three-phase equilibria in density-functional theory: interfacial tensions

Kenichiro Koga, Joseph O. Indekeu

A mean-field density-functional model for three-phase equilibria in fluids (or other soft condensed matter) with two spatially varying densities is analyzed analytically and numeri…

Glassy dynamics in strongly anharmonic chains of oscillators

Wojciech De Roeck, François Huveneers

We review the mechanism for transport in strongly anharmonic chains of oscillators near the atomic limit where all oscillators are decoupled. In this regime, the motion of most osc…

Rate dependence of current and fluctuations in jump models with negative differential mobility

Gianluca Teza, Stefano Iubini, Marco Baiesi +2

Negative differential mobility is the phenomenon in which the velocity of a particle decreases when the force driving it increases. We study this phenomenon in Markov jump models w…

Frenesy: time-symmetric dynamical activity in nonequilibria

Christian Maes

We review the concept of dynamical ensembles in nonequilibrium statistical mechanics as specified from an action functional or Lagrangian on spacetime. There, under local detailed…

Nonequilibrium corrections to gradient flow

Christian Maes, Karel Netočný

The force on a probe induced by a nonequilibrium medium is in general nongradient. We detail the mechanism of that feature via nonequilibrium response theory. The emergence of nong…

Producing suprathermal tails in the stationary velocity distribution

Thibaut Demaerel, Wojciech De Roeck, Christian Maes

We revisit effective scenarios for the origin of heavy tails in stationary velocity distributions. A first analysis combines localization with diffusive acceleration. That gets rea…
