Kinetic models of self-organization effects in lattice systems

Dubrovskii, V.G.; Cirlin, G.E.; Bauman, D.A.; Kozachek, V.V. - In: Physica A: Statistical Mechanics and its Applications 260 (1998) 3, pp. 349-373

A non-linear model for time-dependent occupation of lattice gas sites is studied. A self-consistent approximation for the diffusion operator is proposed and studied in discrete and continual forms. It is shown that self-organization effects in the spinodal region lead to a spontaneous...

Classical trajectories: A powerful tool for solving tunneling problems

Sels, Dries; Brosens, Fons; Magnus, Wim - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 1, pp. 78-81

In the realm of Ehrenfest’s theorem, classical trajectories obeying Newton’s laws have been proven useful to construct explicit solutions to the time-dependent Wigner–Liouville equation. Whereas previous works have particularly focused on the initial distribution function as a vehicle...
