Probing valley phenomena with gate-defined valley splitters
Juan Daniel Torres Luna, Kostas Vilkelis, Antonio L. R. Manesco
Despite many reports of valley-related phenomena in graphene and its multilayers, current transport experiments cannot probe valley phenomena without the application of external fi…
Chiral adiabatic transmission protected by Fermi surface topology
Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco +3
We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the n…
Fermionic quantum computation with Cooper pair splitters
Kostas Vilkelis, Antonio Manesco, Juan Daniel Torres Luna +3
We propose a practical implementation of a universal quantum computer that uses local fermionic modes (LFM) rather than qubits. The device layout consists of quantum dots tunnel co…
Aharonov-Bohm magnetism in open Fermi surfaces
Kostas Vilkelis, Ady Stern, Anton Akhmerov
Orbital diamagnetism requires closed orbits according to the Liftshiftz-Kosevich theory. Therefore, one might expect that open Fermi surfaces do not have a diamagnetic response. Co…
Electronic properties of InAs/EuS/Al hybrid nanowires
Chun-Xiao Liu, Sergej Schuwalow, Yu Liu +4
We study the electronic properties of InAs/EuS/Al heterostructures as explored in a recent experiment [S. Vaitiekenas \emph{et al.}, Nat. Phys. (2020)], combining both spectroscopi…
Bloch-Lorentz magnetoresistance oscillations in delafossites
Kostas Vilkelis, Lin Wang, Anton Akhmerov
Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO and PtCoO) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show…
