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…
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…
Exotic Stochastic Processes from Complex Quantum Environments
Dimitri Kusnezov, Aurel Bulgac, Giu Do Dang
Stochastic processes are shown to emerge from the time evolution of complex quantum systems. Using parametric, banded random matrix ensembles to describe a quantum chaotic environm…
