Negative flow of energy in a mechanical wave
A. Matulis, A. Acus
A classical system, which is analogous to the quantum one with a backflow of probability, is proposed. The system consists of a chain of masses interconnected by springs, as well a…
Classical analog to the Airy wave packet
A. Matulis, A. Acus
The solution of the Liouville equation for the ensemble of free particles is presented and the classical analog to the quantum accelerating Airy wave packet is constructed and disc…
Scattering of a Dirac electron on a mass barrier
A. Matulis, M. Ramezani Masir, F. M. Peeters
The interaction of a wave packet (and in particular the wave front) with a mass barrier is investigated in one dimension. We discuss the main features of the wave packet that are i…
Scattering of Dirac electrons by circular mass barriers: valley filter and resonant scattering
M. Ramezani Masir, A. Matulis, F. M. Peeters
The scattering of two-dimensional (2D) massless Dirac electrons is investigated in the presence of a random array of circular mass barriers. The inverse momentum relaxation time an…
Quasi-bound states of Schrodinger and Dirac electrons in magnetic quantum dot
M. Ramezani Masir, A. Matulis, F. M. Peeters
The properties of a two-dimensional electron are investigated in the presence of a circular step magnetic field profile. Both electrons with parabolic dispersion as well as Dirac e…
Quasi-bound states of quantum dots in single and bilayer graphene
A. Matulis, F. M. Peeters
Dirac fermions interacting with a cylindrically symmetric quantum dot potential created in single and bilayer graphene are not confined but form quasi-bound states. The broadening…
