First-Principles Wannier Representation of Proximity Effects
Yaroslav Zhumagulov, Johan Félisaz, Stepan S. Tsirkin +2
Proximity effects in layered heterostructures are usually represented by static parameters fitted to first-principles bands, which discards the energy dependence of the virtual hyb…
Dirac Landau levels for surfaces with constant negative curvature
Maximilian Fürst, Denis Kochan, Ioachim-Gheorghe Dusa +2
Studies of the formation of Landau levels based on the Schrödinger equation for electrons constrained to curved surfaces have a long history. These include as prime examples surfac…
Spin-orbit and exchange proximity couplings in graphene/1T-TaS heterostructure triggered by a charge density wave
Karol Szałowski, Marko Milivojević, Denis Kochan +1
Proximity-induced fine features and spin-textures of the electronic bands in graphene-based van der Waals heterostructures can be explored from the point of tailoring a twist angle…
Spin relaxation, Josephson effect and Yu-Shiba-Rusinov states in superconducting bilayer graphene
Michael Barth, Jacob Fuchs, Denis Kochan
Bilayer graphene has two non-equivalent sublattices and, therefore, the same adatom impurity can manifest in spectrally distinct ways-sharp versus broad resonances near the charge…
Counterintuitive gate dependence of weak antilocalization in bilayer graphene/WSe heterostructures
Julia Amann, Tobias Völkl, Tobias Rockinger +6
Strong gate control of proximity-induced spin-orbit coupling was recently predicted in bilayer graphene/transition metal dichalcogenides (BLG/TMDC) heterostructures, as charge carr…
Impurity resonance effects in graphene impurity location, concentration and sublattice occupation
Yuriy G. Pogorelov, Vadim M. Loktev, Denis Kochan
Unique electronic band structure of graphene with its semi-metallic features near the charge neutrality point is sensitive to impurity effects. Using the Lifshitz and Anderson impu…
