Microwave realization of a periodically driven system
Autor: S Gehler, T Tudorovskiy, C Schindler, U Kuhl, H-J Stöckmann
Publikováno v: New Journal of Physics, Vol 15, Iss 8, p 083030 (2013)
A realization of a periodically driven microwave system is presented. The principal element of the scheme is a variable capacity, i.e. a varicap, introduced as an element of the resonant circuit. Sideband structures, corresponding to different drivin

We employ the tight-binding propagation method to study Klein tunneling and quantum interference in large graphene systems. With this efficient numerical scheme, we model the propagation of a wave packet through a potential barrier and determine the

Spectral series of the Schrödinger operator in thin waveguides with periodic structure, I adiabatic approximation and semiclassical asymptotics in the 2D case

Asymptotic formulas for the eigenvalues (energy levels) of the 2D and 3D stationary Schrodinger operators describing the states of a quantum particle in the waveguide formed by soft walls characterized by a periodic parabolic confinement potential sl

Spectral flow for Aharonov-Bohm rings generated by zero-mass lines
Autor: Vladimir E. Nazaikinskii, Mikhail I. Katsnelson, T. Tudorovskiy
Publikováno v: physica status solidi (RRL) - Rapid Research Letters. 7:157-159
We found that the spectrum of the linear dispersion mode localized along the zero-mass line for variable mass Dirac fermions shows the nonzero spectral flow as a function of the external magnetic field B. This happens due to the Aharonov--Bohm effect

Semiclassical theory of potential scattering for massless Dirac fermions

Annals of Physics, 333, 155-197
In this paper we study scattering of two-dimensional massless Dirac fermions by a potential that depends on a single Cartesian variable. Depending on the energy of the incoming particle and its angle of incidence, there are three different regimes of

We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in weak magnetic field. Close enough to the neutrality point, coexistence of electrons and holes in each layer leads to a dramatic

Coulomb drag between two unhybridized graphene sheets separated by a dielectric spacer has recently attracted considerable theoretical interest. We first review, for the sake of completeness, the main analytical results which have been obtained by ot

Low-Frequency Inter-Valley Plasmons In Graphene

The spectrum of plasma waves in graphene is theoretically studied within the random phase approximation taking into account the local field effects due to the lattice periodicity. Near the corners of the plasmon Brillouin zone we find a new, low‐fr

We consider an application of a general theory for cavities with point-like perturbations for a rectangular shape. Hereby we concentrate on experimental wave patterns obtained for nearly degenerate states. The nodal lines in these patterns may be bro
