Quantum transmission conditions for diffusive transport in graphene with steep potentials
Luigi Barletti, Claudia Negulescu
We present a formal derivation of a drift-diffusion model for stationary electron transport in graphene, in presence of sharp potential profiles, such as barriers and steps. Assumi…
Solvable models of quantum beating
R. Carlone, R. Figari, C. Negulescu +1
We review some results about the suppression of quantum beating in a one dimensional nonlinear double well potential. We implement a single particle double well potential model, ma…
The quantum beating and its numerical simulation
Raffaele Carlone, Rodolfo Figari, Claudia Negulescu
We examine the suppression of quantum beating in a one dimensional non- linear double well potential, made up of two focusing nonlinear point interactions. The investigation of the…
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…
De coherence for a heavy particle interacting with a light one: new analysis and numerics
Riccardo Adami, Maxime Hauray, Claudia Negulescu
We study the dynamics of a quantum heavy particle undergoing a repulsive interaction with a light one. The main motivation is the detailed description of the loss of coherence indu…
