Spatial Distributions of Observables in Systems under Thermal Gradients
Kenichiro Aoki Dimitri Kusnezov
Departures of observables from their thermal equilibrium expectation values are studied under heat flow in steady-state non-equilibrium environments. The relation between the spati…
Non-Equilibrium Statistical Mechanics of Classical and Quantum Systems
Dimitri Kusnezov, Eric Lutz, Kenichiro Aoki
We study the statistical mechanics of classical and quantum systems in non-equilibrium steady states. Emphasis is placed on systems in strong thermal gradients. Various measures an…
Lyapunov Exponents, Transport and the Extensivity of Dimensional Loss
Kenichiro Aoki, Dimitri Kusnezov
An explicit relation between the dimensional loss (), entropy production and transport is established under thermal gradients, relating the microscopic and macroscopic behavior…
On the Violations of Local Equilibrium and Linear Response
Kenichiro Aoki, Dimitri Kusnezov
We study how local equilibrium, and linear response predictions of transport coefficients are violated as systems move far from equilibrium. This is done by studying heat flow in c…
Scheme Dependence of the Wilsonian Effective Action and Sharp Cutoff Limit of the Flow Equation
Jun-Ichi Sumi, Wataru Souma, Ken-Ichi Aoki +2
The cutoff scheme dependence in the several formulations of the Exact Renormalization Group (ERG) is investigated. It is shown that the cutoff scheme dependence of the Wilsonian ef…
Classical Lattice Field Theory in Strong Thermal Gradients
Kenichiro Aoki, Dimitri Kusnezov
The dynamics of classical theory under weak and strong thermal gradients is studied. We obtain the thermal conductivity of the theory including its temperature dependence. Un…
