Hydrodynamic limit for the velocity flip model [PDF]
Stochastic Processes and their Applications, 2013 We study the diffusive scaling limit for a chain of $N$ coupled oscillators. In order to provide the system with good ergodic properties, we perturb the Hamiltonian dynamics with random flips of velocities, so that the energy is locally conserved.

Hydrodynamic limit of order book dynamics [PDF]
Probability in the Engineering and Informational Sciences, 2016 In this paper, we establish a fluid limit for a two--sided Markov order book model. Our main result states that in a certain asymptotic regime, a pair of measure-valued processes representing the "sell-side shape" and "buy-side shape" of an order book ...

Hydrodynamic scaling limit of continuum solid-on-solid model [PDF]
Journal of Applied Mathematics, 2006 A fourth-order nonlinear evolution equation is derived from a microscopic model for surface diffusion, namely, the continuum solid-on-solid model.

Longitudinal sound and diffusion in holographic massive gravity [PDF]
Journal of High Energy Physics, 2019 We consider a simple class of holographic massive gravity models for which the dual field theories break translational invariance spontaneously. We study, in detail, the longitudinal sector of the quasi-normal modes at zero charge density.

Hydrodynamic limit of a disordered lattice gas [PDF]
Probability Theory and Related Fields, 2003 We consider a model of lattice gas dynamics in the d-dimensional cubic lattice in the presence of disorder. If the particle interaction is only mutual exclusion and if the disorder field is given by i.i.d.

Super-hydrodynamic limit in interacting particle systems [PDF]
Journal of Statistical Physics, 2013 This paper is a follow-up of the work initiated in [3], where it has been investigated the hydrodynamic limit of symmetric independent random walkers with birth at the origin and death at the rightmost occupied site.

Hydrodynamic limit for a disordered harmonic chain [PDF]
Communications in Mathematical Physics, 2019 We consider a one-dimensional unpinned chain of harmonic oscillators with random masses. We prove that after hyperbolic scaling of space and time the distributions of the elongation, momentum and energy converge to the solution of the Euler equations ...

Unbounded entanglement production via a dissipative impurity
SciPost Physics, 2022 We investigate the entanglement dynamics in a free-fermion chain initially prepared in a Fermi sea and subjected to localized losses (dissipative impurity).

Quasi-Static Hydrodynamic Limits [PDF]
Journal of Statistical Physics, 2015 We consider hydrodynamic limits of interacting particles systems with open boundaries, where the exterior parameters change in a time scale slower than the typical relaxation time scale. The limit deterministic profiles evolve quasi-statically. These limits define rigorously the thermodynamic quasi static transformations also for transition between non-
