Effective Landé factors for an electrostatically defined quantum point contact in silicene
Bartłomiej Rzeszotarski, Alina Mreńca-Kolasińska, François M. Peeters +1
The transconductance and effective Landé factors for a quantum point contact defined in silicene by the electric field of a split gate is investigated. The strong spin-orbit…
Fast evaluation of interaction integrals for confined systems with machine learning
Alina Mreńca-Kolasińska, Krzysztof Kolasiński, Bartłomiej Szafran
The calculation of interaction integrals is a bottleneck for the treatment of many-body quantum systems due to its high numerical cost. We conduct configuration interaction calcula…
Aharonov-Bohm oscillations of four-probe resistance in topological quantum rings in silicene and bilayer graphene
Bartłomiej Rzeszotarski, Alina Mreńca-Kolasińska, Bartłomiej Szafran
We consider observation of Aharonov-Bohm oscillations in clean systems based on the flow of topologically protected currents in silicene and bilayer graphene. The chiral channels i…
Topologically protected wave packets and quantum rings in silicene
B. Szafran, B. Rzeszotarski, A. Mreńca-Kolasińska
We study chiral wave packets moving along the zero-line of a symmetry breaking potential of vertical electric field in buckled silicene using an atomistic tight-binding approach wi…
Electron interferometry and quantum spin Hall phase in silicene
Bartłomiej Rzeszotarski, Alina Mreńca-Kolasińska, Bartłomiej Szafran
We discuss devices for detection of the topological insulator phase based on the two-path electron interference. For that purpose we consider buckled silicene for which a local ene…
Manipulating quantum Hall edge channels in graphene through Scanning Gate Microscopy
Lennart Bours, Stefano Guiducci, Alina Mreńca-Kolasińska +3
We show evidence of the backscattering of quantum Hall edge channels in a narrow graphene Hall bar, induced by the gating effect of the conducting tip of a Scanning Gate Microscope…
