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. bounded random variables, we prove the almost sure existence of the hydrodynamical limit in dimension d>2.

Deriving the Born Rule from Boundary-Induced Alignment in Chronon Field Theory
Reports in Advances of Physical SciencesIn this paper, we derive the Born rule in Chronon Field Theory (CFT) from first principles under realistic measurement assumptions. A recent work in CFT shows that Lorentzian signature and causal structure emerge dynamically from a unit-norm constraint ...

Weak Limits of the Quantum Hydrodynamic Model [PDF]
VLSI Design, 1998 A numerical study of the dispersive limit of the quantum hydrodynamic equations for semiconductors is presented. The solution may develop high frequency oscillations when the scaled Planck constant is small. Numerical evidence is given of the fact that in such cases the solution does not converge to the solution of the formal limit equations.

Probing the hydrodynamic limit of (super)gravity [PDF]
Journal of High Energy Physics, 2015 We study the long-wavelength effective description of two general classes of charged dilatonic (asymptotically flat) black p-branes including D/NS/M-branes in ten and eleven dimensional supergravity. In particular, we consider gravitational brane solutions in a hydrodynamic derivative expansion (to first order) for arbitrary dilaton coupling and for ...

A molecular theory of large-solute diffusion
Condensed Matter Physics, 2007 The limit of a large solute in the molecular theory of diffusion developed by Yamaguchi et al. [Yamaguchi T. et al., J. Chem. Phys., 2005, 123, 034504] is studied.

Hydrodynamic Limit for a Disordered Harmonic Chain [PDF]
Communications in Mathematical Physics, 2018 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. Anderson localization decouples the mechanical modes from the thermal modes, allowing the closure of ...

THE HYDRODYNAMICAL LIMIT OF QUANTUM HALL SYSTEM [PDF]
International Journal of Modern Physics B, 2001 We study the current algebra of FQHE systems in the hydrodynamical limit of small amplitude, long-wavelength fluctuations. We show that the algebra simplifies considerably in this limit. The Hamiltonian is expressed in a current–current form and the operators creating inter-Landau level and lowest Landau level collective excitations are identified.

Inhomogeneous quenches in the transverse field Ising chain: scaling and front dynamics
SciPost Physics, 2017 We investigate the non-equilibrium dynamics of the transverse field quantum Ising chain evolving from an inhomogeneous initial state given by joining two macroscopically different semi-infinite chains.

Gradient resummation for nonlinear chiral transport: an insight from holography
European Physical Journal C: Particles and Fields, 2019 Nonlinear transport phenomena induced by chiral anomaly are explored within a 4D field theory defined holographically as $$U(1)_V\times U(1)_A$$ U(1)V×U(1)A Maxwell–Chern–Simons theory in Schwarzschild-$$AdS_5$$ AdS5 .
