The existence of Burnett coefficients in the periodic Lorentz gas
N. I. Chernov, C. P. Dettmann
The linear super-Burnett coefficient gives corrections to the diffusion equation in the form of higher derivatives of the density. Like the diffusion coefficient, it can be express…
Hamiltonian for a restricted isoenergetic thermostat
C. P. Dettmann
Nonequilibrium molecular dynamics simulations often use mechanisms called thermostats to regulate the temperature. A Hamiltonian is presented for the case of the isoenergetic (cons…
Spectrum of stochastic evolution operators: Local matrix representation approach
Predrag Cvitanovic, Niels Sondergaard, Gergely Palla +2
A matrix representation of the evolution operator associated with a nonlinear stochastic flow with additive noise is used to compute its spectrum. In the weak noise limit a perturb…
Stochastic trace formulas
C. P. Dettmann, Gergely Palla, Niels Søndergaard +1
The spectrum of the evolution Operator associated with a nonlinear stochastic flow with additive noise is evaluated by diagonalization in a polynomial basis. The method works for a…
