Anisotropic magnetoresistance of two-dimensional Rashba systems with in-plane Zeeman field and point-like disorder
Igor Gornyi, Alexander Khaetskii
We study the dc conductivity of a two-dimensional Rashba system with an in-plane Zeeman field and delta-correlated scalar disorder. We show that, although the field deforms the two…
Band structure and optical response of Kekulé-modulated model
Luis E. Sánchez-González, Miguel A. Mojarro, Jeús A. Maytorena +1
We study the electronic band structure and optical response of a hybrid model, a model featuring a Kekulé pattern modulation. Such a hybr…
Valley-dependent transport through graphene quantum dots due to proximity-induced, staggered spin-orbit couplings
A. Belayadi, P. Vasilopoulos, N. Sandler
We study a system composed of graphene decorated with an array of islands with C_3v symmetry that induce quantum dot (IQD) regions via proximity effects and give rise to several sp…
Photo-induced Multiply Quantized Vortex States in Dirac-like Materials
Lauren I. Massaro, Connor Meese, Nancy P. Sandler +1
Subjecting a massive two-dimensional Dirac material to a vortex light beam provides a mechanism for the photo-induction of multiply quantized vortices. Using Floquet theory, we sho…
Interplay between strain and size quantization in a class of topological insulators based on inverted-band semiconductors
Alexander Khaetskii, Vitaly Golovach, Arnold Kiefer
We consider surface states in semiconductors with inverted-band structures, such as -Sn and HgTe. The main interest is the interplay of the effect of a strain of an arbitrary si…
Thermal difference reflectivity of tilted 2D Dirac materials
M. A. Mojarro, R. Carrillo-Bastos, Jesús A. Maytorena
Deviation from perfect conical dispersion in Dirac materials, such as the presence of mass or tilting, enhances control and directionality of electronic transport. To identify thes…
