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…
Isotropic 3D topological phases with broken time reversal symmetry
Helene Spring, Anton R. Akhmerov, Daniel Varjas
Axial vectors, such as current or magnetization, are commonly used order parameters in time-reversal symmetry breaking systems. These vectors also break isotropy in three dimension…
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…
Lack of near-sightedness principle in non-Hermitian systems
Helene Spring, Viktor Könye, Anton R. Akhmerov +1
The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with…
Double-Fourier engineering of Josephson energy-phase relationships applied to diodes
A. Mert Bozkurt, Jasper Brookman, Valla Fatemi +1
We present a systematic method to design arbitrary energy-phase relations using parallel arms of two series Josephson tunnel junctions each. Our approach employs Fourier engineerin…
Design of a Majorana trijunction
Juan Daniel Torres Luna, Sathish R. Kuppuswamy, Anton R. Akhmerov
Braiding of Majorana states demonstrates their non-Abelian exchange statistics. One implementation of braiding requires control of the pairwise couplings between all Majorana state…
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…
Landau quantization near generalized Van Hove singularities: Magnetic breakdown and orbit networks
V. A. Zakharov, A. Mert Bozkurt, A. R. Akhmerov +1
We develop a theory of magnetic breakdown (MB) near high-order saddle points in the dispersions of two-dimensional materials, where two or more semiclassical cyclotron orbits appro…
Phase transitions of wave packet dynamics in disordered non-Hermitian systems
Helene Spring, Viktor Könye, Fabian A. Gerritsma +2
Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of en…
