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…
Link between supercurrent diode and anomalous Josephson effect revealed by gate-controlled interferometry
Simon Reinhardt, Tim Ascherl, Andreas Costa +9
In Josephson diodes the asymmetry between positive and negative current branch of the current-phase relation leads to a polarity-dependent critical current and Josephson inductance…
Swapping exchange and spin-orbit induced correlated phases in proximitized Bernal bilayer graphene
Yaroslav Zhumagulov, Denis Kochan, Jaroslav Fabian
Ex-so-tic van der Waals heterostructures take advantage of the electrically tunable layer polarization to swap proximity exchange and spin-orbit coupling in the electronically acti…
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…
Emergent correlated phases in rhombohedral trilayer graphene induced by proximity spin-orbit and exchange coupling
Yaroslav Zhumagulov, Denis Kochan, Jaroslav Fabian
The impact of proximity-induced spin-orbit and exchange coupling on the correlated phase diagram of rhombohedral trilayer graphene (RTG) is investigated theoretically. By employing…
Phenomenological Theory of the Supercurrent Diode Effect: The Lifshitz Invariant
Denis Kochan, Andreas Costa, Iaroslav Zhumagulov +1
Nonreciprocal phenomena in the normal state are well established and key to many commercial applications. In contrast, superconducting analogs, such as the superconducting diode ef…
