Hybrid classical-quantum models for charge transport in graphene with sharp potentials
Luigi Barletti, Claudia Negulescu
We give a concise account on the derivation of hybrid quantum-classical models for stationary electron transport in graphene, in presence of sharp potential steps of barriers. A qu…
A hybrid method for anisotropic elliptic problems based on the coupling of an Asymptotic-Preserving method with the Asymptotic-Limit model
Anais Crestetto, Fabrice Deluzet, Claudia Negulescu
This paper presents a hybrid numerical method to solve efficiently a class of highly anisotropic elliptic problems. The anisotropy is aligned with one coordinate-axis and its stren…
Numerical analysis of an asymptotic-preserving scheme for anisotropic elliptic equations
Alexei Lozinski, Jacek Narski, Claudia Negulescu
The main purpose of the present paper is to study from a numerical analysis point of view some robust methods designed to cope with stiff (highly anisotropic) elliptic problems. Th…
