Adding decoherence to the Wigner equation
Luigi Barletti, Giovanni Frosali, Elisa Giovannini
Starting from the detailed description of the single-collision decoherence mechanism proposed by Adami, Hauray and Negulescu, we derive a Wigner equation endowed with a decoherence…
A Symbolic Method for the Analysis of a Nonlinear Two-Mass-Skate Model
Francesco Ricci, Giovanni Frosali
Multibody systems usually give rise to complex nonlinear dynamics, and the bicycle is not an exception. Even a simple model as the Two-Mass-Skate presents a long expression of the…
Semiclassical hydrodynamics of a quantum Kane model for semiconductors
Luigi Barletti, Giovanni Borgioli, Giovanni Frosali
In this paper we derive a semiclassical hydrodynamic system for electron densities and currents in the two energy bands of a semiconductor. We use the semiclassical Wigner equation…
Rigorous drift-diffusion asymptotics of a high-field quantum transport equation
Chiara Manzini, Giovanni Frosali
The asymptotic analysis of a linear high-field Wigner-BGK equation is developped by a modified Chapman-Enskog procedure. By an expansion of the unknown Wigner function in powers of…
