Quantum interference tuning of spin-orbit coupling in twisted van der Waals trilayers
Csaba G. Péterfalvi, Alessandro David, Péter Rakyta +2
We show that in van der Waals stacks of twisted hexagonal layers the proximity induced Rashba spin-orbit coupling can be affected by quantum interference. We calculate the quantum…
Hyperfine-induced dephasing in three-electron spin qubits
Csaba G. Péterfalvi, Guido Burkard
We calculate the pure dephasing time of three-electron exchange-only qubits due to interaction with the nuclear hyperfine field. Within the spin subspace, we derive for…
Boundary conditions for transition-metal dichalcogenide monolayers in the continuum model
Csaba G. Péterfalvi, Andor Kormányos, Guido Burkard
We derive the boundary conditions for MoS and similar transition-metal dichalcogenide honeycomb (2H polytype) monolayers with the same type of H…
Suppression of single-molecule conductance fluctuations using extended anchor groups on graphene and carbon-nanotube electrodes
Csaba G. Péterfalvi, Colin J. Lambert
Devices formed from single molecules attached to noble-metal electrodes exhibit large conductance fluctuations, which inhibit their development as reproducible functional units. We…
Intraband electron focusing in bilayer graphene
Csaba G. Péterfalvi, László Oroszlány, Colin J. Lambert +1
We propose an implementation of a valley selective electronic Veselago lens in bilayer graphene. We demonstrate that in the presence of an appropriately oriented potential step, lo…
Catastrophe optics of caustics in single and bilayer graphene: fine structure of caustics
Csaba Péterfalvi, András Pályi, Ádám Rusznyák +2
We theoretically study the scattering of a plane wave of a ballistic electron on a circular n-p junction in single and bilayer graphene. We compare the exact wave function inside t…
Two-dimensional electron scattering in regions of nonuniform spin-orbit coupling
András Pályi, Csaba Péterfalvi, József Cserti
We present a theoretical study of elastic spin-dependent electron scattering caused by a nonuniform Rashba spin-orbit coupling strength. Using the spin-generalized method of partia…
