Hydrodynamic Limit for Interacting Neurons [PDF]

open access: yesJournal of Statistical Physics, 2014
This paper studies the hydrodynamic limit of a stochastic process describing the time evolution of a system with N neurons with mean-field interactions produced both by chemical and by electrical synapses. This system can be informally described as follows.

Hydrodynamic Limit of Multiple SLE [PDF]

open access: yesJournal of Statistical Physics, 2018
Recently del Monaco and Schlei inger addressed an interesting problem whether one can take the limit of multiple Schramm--Loewner evolution (SLE) as the number of slits $N$ goes to infinity. When the $N$ slits grow from points on the real line ${\mathbb{R}}$ in a simultaneous way and go to infinity within the upper half plane ${\mathbb{H}}$, an ...

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma

open access: yesJournal of High Energy Physics, 2022
We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant g. The spin relaxation rate Γ s in spin hydrodynamics is shown to be Γ s ~ g 4 log(1/g)T(T/M)2 in the heavy ...

Non-Perturbative Hydrodynamic Limits [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2013
We introduce non-perturbative analytical techniques for the derivation of the hydrodynamic manifolds from kinetic equations. The new approach is analogous to the Schwinger-Dyson equation of quantum field theories, and its derivation is demonstrated with the construction of the exact diffusion manifold for a model kinetic equation. The novel approach is

Super-Ballistic Width Dependence of Thermal Conductivity in Graphite Nanoribbons and Microribbons

open access: yesNanomaterials, 2023
The super-ballistic temperature dependence of thermal conductivity, facilitated by collective phonons, has been widely studied. It has been claimed to be unambiguous evidence for hydrodynamic phonon transport in solids.

Hydrodynamic transport and violation of the viscosity-to-entropy ratio bound in nodal-line semimetals

open access: yesPhysical Review Research, 2021
The ratio between the shear viscosity and the entropy η/s is considered a universal measure of the strength of interactions in quantum systems. This quantity was conjectured to have a universal lower bound (1/4π)ℏ/k_{B}, which indicates a very strongly ...

Entropy-limited hydrodynamics: a novel approach to relativistic hydrodynamics [PDF]

open access: yesComputational Astrophysics and Cosmology, 2017
AbstractWe present entropy-limited hydrodynamics (ELH): a new approach for the computation of numerical fluxes arising in the discretization of hyperbolic equations in conservation form. ELH is based on the hybridisation of an unfiltered high-order scheme with the first-order Lax-Friedrichs method.

Front dynamics in the XY chain after local excitations

open access: yesSciPost Physics, 2020
We study the time evolution of magnetization and entanglement for initial states with local excitations, created upon the ferromagnetic ground state of the XY chain.

Propagating density fluctuations in hydrodynamics and beyond

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020
Density fluctuations in simple liquids are analysed in the context of three different and widely used formalisms, whose equivalence in the hydrodynamic limit is shown.
