Tuning topological superconductivity within the -- model of twisted bilayer cuprates
Maciej Fidrysiak, Bartłomiej Rzeszotarski, Józef Spałek
We carry out a theoretical study of unconventional superconductivity in twisted bilayer cuprates (TBC) as a function of electron density and layer twist angle. The bilayer --…
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…
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…
Spin-active devices based on graphene / WSe heterostructure
Alina Mrenca-Kolasinska, Bartlomiej Rzeszotarski, Bartlomiej Szafran
We consider graphene on monolayer WSe and the spin-orbit coupling induced by the transition-metal dichalcogenide substrate for application to spin-active devices. We study quan…
Electrical control of a confined electron spin in a silicene quantum dot
Bartlomiej Szafran, Alina Mrenca-Kolasinska, Bartlomiej Rzeszotarski +1
We study spin control for an electron confined in a flake of silicene. We find that the lowest-energy conduction-band levels are split by the diagonal intrinsic spin-orbit coupling…
Electron spin inversion in gated silicene nanoribbons
Bartłomiej Rzeszotarski, Bartłomiej Szafran
We study locally gated silicene nanoribbons as spin active devices. We find that the gated segments of nanoribbons with zigzag edge can be used to perform a spin inversion for the…
Spin inversion in fluorinated graphene n-p junction
Bartlomiej Rzeszotarski, Alina Mrenca-Kolasinska, Bartlomiej Szafran
We consider a dilute fluorinated graphene nanoribbon as a spin-active element. The fluorine adatoms introduce a local spin-orbit Rashba interaction that induces spin-precession for…
Tunneling conductance in half-metal/conical magnet/superconductor junctions in the adiabatic and non-adiabatic regime: self-consistent calculations
P. Wójcik, B. Rzeszotarski, M. Zegrodnik
The tunneling conductance in the half-metal/conical magnet/superconductor (HM/CM/SC) is investigated by the use of the combined Blonder-Tinkham-Klapwijk (BTK) formalism and the Bog…
