Parametrically driven nonlinear Dirac equation with arbitrary nonlinearity
(IOP Publishing, 2020-01)
The damped and parametrically driven nonlinear Dirac equation with arbitrary nonlinearity parameter κ is analyzed, when the external force is periodic in space and given by f(x) = r cos(Kx), both numerically and in a ...

Linear response in the uniformly heated granular gas
(American Physical Society, 2021-08)
We analyze the linear response properties of the uniformly heated granular gas. The intensity of the stochastic driving fixes the value of the granular temperature in the nonequilibrium steady state reached by the ...

Strong nonexponential relaxation and memory effects in a fluid with nonlinear drag
(American Physical Society, 2021-12)
We analyze the dynamical evolution of a fluid with nonlinear drag, for which binary collisions are elastic, described at the kinetic level by the Enskog-Fokker-Planck equation. This model system, rooted in the theory of ...
