Time dependent electric transport in nodal-loop semimetals
Zoltán Okvátovity, László Oroszlány, Balázs Dóra
Close to the Fermi energy, nodal loop semimetals have a torus-shaped, strongly anisotropic Fermi surface which affects their transport properties. Here we investigate the non-equil…
Competition of trivial and topological phases in patterned graphene based heterostructures
Zoltán Tajkov, János Koltai, József Cserti +1
We explore the effect of mechanical strain on the electronic spectrum of patterned graphene based heterostructures. We focus on the competition of Kekulé-O type distortion favoring…
Topological Phase Diagram of BiTeX--Graphene Hybrid Structures
Zoltán Tajkov, Dávid Visontai, László Oroszlány +1
Combining graphene with other novel layered materials is a possible way for engineering the band structure of charge carriers. Strong spin-orbit coupling in BiTeX compounds and the…
Poor man's topological quantum gate based on the Su-Schrieffer-Heeger model
Péter Boross, János K. Asbóth, Gábor Széchenyi +2
Topological properties of quantum systems could provide protection of information against environmental noise, and thereby drastically advance their potential in quantum informatio…
Exchange interactions from a nonorthogonal basis set: from bulk ferromagnets to the magnetism in low-dimensional graphene systems
László Oroszlány, Jaime Ferrer, András Deák +2
We present a computational method to determine the exchange constants in isotropic spin models. The method uses the Hamiltonian and overlap matrices computed from density functiona…
Topological and trivial magnetic oscillations in nodal loop semimetals
László Oroszlány, Balázs Dóra, József Cserti +1
Nodal loop semimetals are close descendants of Weyl semimetals and possess a topologically dressed band structure. We argue by combining the conventional theory of magnetic oscilla…
