Special Relativity in Quantum Phase Space
Daniela Dragoman
A phase space treatment of special relativity of quantum systems is developed. In this approach a quantum particle remains localized if subject to inertial transformations, the loc…
Negative Differential Resistance of Electrons in Graphene Barrier
Daniela Dragoman, Mircea Dragoman
The graphene is a native two-dimensional crystal material consisting of a single sheet of carbon atoms. In this unique one-atom-thick material, the electron transport is ballistic…
Evidence Against Klein Paradox in Graphene
Daniela Dragoman
It is demonstrated that both transmission and reflection coefficients associated to the Klein paradox at a step barrier are positive and less than unity, so that the particle-antip…
The Aharonov-Bohm Effect in the Momentum Space
D. Dragoman, S. Bogdan
The Schrodinger formalism of quantum mechanics is used to demonstrate the existence of the Aharonov-Bohm effect in momentum space and set-ups for experimentally demonstrating it ar…
Momentum Jumps in Quasi-2D Ballistic Systems
Daniela Dragoman
It is shown that the depopulation of magnetoelectric subbands of ballistic electrons in quasi-2D systems, due to an increased magnetic field parallel to the 2D electron gas plane,…
