Ensemble Inequivalence in Long-Range Quantum Spin Systems
Daniel Arrufat-Vicente, David Mukamel, Stefano Ruffo +1
Ensemble inequivalence occurs when a systems thermodynamic properties vary depending on the statistical ensemble used to describe it. This phenomenon is known to happen in systems…
Ensemble inequivalence in long-range quantum systems
Nicolò Defenu, David Mukamel, Stefano Ruffo
Ensemble inequivalence, i.e. the possibility of observing different thermodynamic properties depending on the statistical ensemble which describes the system, is one of the hallmar…
Mixed Order Phase Transitions
David Mukamel
Mixed order phase transitions are transitions which have common features with both first order and second order transitions. I review some results obtained in the context of one of…
Edge fluctuations and third-order phase transition in harmonically confined long-range systems
Jitendra Kethepalli, Manas Kulkarni, Anupam Kundu +3
We study the distribution of the position of the rightmost particle in a -particle Riesz gas in one dimension confined in a harmonic trap. The particles interact via…
Long-range influence of a pump on a critical fluid
Ydan Ben Dor, Yariv Kafri, David Mukamel +1
A pump coupled to a conserved density generates long-range modulations, resulting from the non-equilibrium nature of the dynamics. We study how these modulations are modified at th…
Harmonically confined long-ranged interacting gas in the presence of a hard wall
Jitendra Kethepalli, Manas Kulkarni, Anupam Kundu +3
In this paper, we compute exactly the average density of a harmonically confined Riesz gas of particles for large in the presence of a hard wall. In this Riesz gas, the par…
Attraction and condensation of driven tracers in a narrow channel
Asaf Miron, David Mukamel, Harald A. Posch
Emergent bath-mediated attraction and condensation arise when multiple particles are simultaneously driven through an equilibrated bath under geometric constraints. While such scen…
Driven tracer dynamics in a one dimensional quiescent bath
Asaf Miron, David Mukamel
The dynamics of a driven tracer in a quiescent bath subject to geometric confinement effectively models a broad range of phenomena. We explore this dynamics in a 1D lattice model w…
Phase transition in a 1d driven tracer model
Asaf Miron, David Mukamel, Harald A. Posch
The effect of particle overtaking on transport in a narrow channel is studied using a 1d model of a driven tracer in a quiescent bath. In contrast with the well-studied non-driven…
Ensemble inequivalence in the Blume-Emery-Griffiths model near a fourth order critical point
V. V. Prasad, Alessandro Campa, David Mukamel +1
The canonical phase diagram of the Blume-Emery-Griffiths (BEG) model with infinite-range interactions is known to exhibit a fourth order critical point at some negative value of th…
Harmonically confined particles with long-range repulsive interactions
Sanaa Agarwal, Abhishek Dhar, Manas Kulkarni +4
We study an interacting system of classical particles on a line at thermal equilibrium. The particles are confined by a harmonic trap and repelling each other via pairwise inte…
Fluctuation-dominated phase ordering at a mixed order transition
Mustansir Barma, Satya N. Majumdar, David Mukamel
Mixed order transitions are those which show a discontinuity of the order parameter as well as a divergent correlation length. We show that the behaviour of the order parameter cor…
Derivation of fluctuating hydrodynamics and crossover from diffusive to anomalous transport in a hard-particle gas
Asaf Miron, Julien Cividini, Anupam Kundu +1
A recently developed non-linear fluctuating hydrodynamics theory has been quite successful in describing various features of anomalous energy transport. However the diffusion and t…
Width scaling of an interface constrained by a membrane
J. Whitehouse, R. A. Blythe, M. R. Evans +1
We investigate the shape of a growing interface in the presence of an impenetrable moving membrane. The two distinct geometrical arrangements of the interface and membrane, obtaine…
Driven tracer with absolute negative mobility
J. Cividini, D. Mukamel, H. A. Posch
Instances of negative mobility, where a system responds to a perturbation in a way opposite to naive expectation, have been studied theoretically and experimentally in numerous non…
Driven tracers in narrow channels
J. Cividini, D. Mukamel, H. A. Posch
Steady state properties of a driven tracer moving in a narrow two dimensional (2D) channel of quiescent medium are studied. The tracer drives the system out of equilibrium, perturb…
Temperature profile and boundary conditions in an anomalous heat transport model
J. Cividini, A. Kundu, A. Miron +1
A framework for studying the effect of the coupling to the heat bath in models exhibiting anomalous heat conduction is described. The framework is applied to the harmonic chain wit…

We study the effect of single biased tracer particle in a bath of other particles performing the random average process (RAP) on an infinite line. We focus on the large time behavi…
Exact extreme value statistics at mixed order transitions
Amir Bar, Satya N. Majumdar, Gregory Schehr +1
We study extreme value statistics (EVS) for spatially extended models exhibiting mixed order phase transitions (MOT). These are phase transitions which exhibit features common to b…
Interface localization in the 2D Ising model with a driven line
Or Cohen, David Mukamel
We study the effect of a one-dimensional driving field on the interface between two coexisting phases in a two dimensional model. This is done by considering an Ising model on a cy…

Julien Cividini, Anupam Kundu, Satya N. Majumdar +1
We study statistics of the gaps in Random Average Process (RAP) on a ring with particles hopping symmetrically, except one tracer particle which could be driven. These particles ho…
Long range correlations in stochastic transport with energy and momentum conservation
Anupam Kundu, Ori Hirschberg, David Mukamel
We consider a simple one dimensional stochastic model of heat transport which locally conserves both energy and momentum and which is coupled to heat reservoirs with different temp…
