Semiclassical theory of anisotropic transport at LaAlO3/SrTiO3 interfaces under in-plane magnetic field
N. Bovenzi, M. Diez
The unconventional magnetotransport at the interface between transition-metal oxides (LAO) and (STO) is frequently related to mobile electrons interacting with…
Wiedemann-Franz-type relation between shot noise and thermal conduction of Majorana surface states in a three-dimensional topological superconductor
N. V. Gnezdilov, M. Diez, M. J. Pacholski +1
We compare the thermal conductance (at temperature ) and the electrical shot noise power (at bias voltage ) of Majorana fermi…
Magnetic breakdown and Klein tunneling in a type-II Weyl semimetal
T. E. O'Brien, M. Diez, C. W. J. Beenakker
The band structure of a type-II Weyl semimetal has pairs of electron and hole pockets that coexist over a range of energies and touch at a topologically protected conical point. We…
Topologically protected charge transfer along the edge of a chiral -wave superconductor
N. V. Gnezdilov, B. van Heck, M. Diez +2
The Majorana fermions propagating along the edge of a topological superconductor with pairing deliver a shot noise power of per eV of voltage b…
Ballistic Josephson junctions in edge-contacted graphene
Victor E. Calado, Srijit Goswami, Gaurav Nanda +6
Hybrid graphene-superconductor devices have attracted much attention since the early days of graphene research. So far, these studies have been limited to the case of diffusive tra…
Giant negative magnetoresistance driven by spin-orbit coupling at the LAO/STO interface
M. Diez, A. M. R. V. L. Monteiro, G. Mattoni +6
The LAO/STO interface hosts a two-dimensional electron system that is unusually sensitive to the application of an in-plane magnetic field. Low-temperature experiments have reveale…
Extended topological group structure due to average reflection symmetry
M. Diez, D. I. Pikulin, I. C. Fulga +1
We extend the single-particle topological classification of insulators and superconductors to include systems in which disorder preserves average reflection symmetry. We show that…
Bimodal conductance distribution of Kitaev edge modes in topological superconductors
M. Diez, I. C. Fulga, D. I. Pikulin +2
A two-dimensional superconductor with spin-triplet p-wave pairing supports chiral or helical Majorana edge modes with a quantized (length -independent) thermal conductance. Suff…
Emergence of massless Dirac fermions in graphene's Hofstadter butterfly at switches of the quantum Hall phase connectivity
M. Diez, J. P. Dahlhaus, M. Wimmer +1
The fractal spectrum of magnetic minibands (Hofstadter butterfly), induced by the moiré super- lattice of graphene on an hexagonal crystal substrate, is known to exhibit gapped Dir…
Phase-locked magnetoconductance oscillations as a probe of Majorana edge states
M. Diez, I. C. Fulga, D. I. Pikulin +3
We calculate the Andreev conductance of a superconducting ring interrupted by a flux-biased Josephson junction, searching for electrical signatures of circulating edge states. Two-…
Andreev reflection from a topological superconductor with chiral symmetry
M. Diez, J. P. Dahlhaus, M. Wimmer +1
It was pointed out by Tewari and Sau that chiral symmetry (H -> -H if e <-> h) of the Hamiltonian of electron-hole (e-h) excitations in an N-mode superconducting wire is associated…
Bias-dependent D'yakonov-Perel' spin relaxation in bilayer graphene
Mathias Diez, Guido Burkard
We calculate the spin relaxation time of mobile electrons due to spin precession between random impurity scattering (D'yakonov-Perel' mechanism) in electrically gated bilayer graph…
Local quenches in frustrated quantum spin chains: global vs. subsystem equilibration
Mathias Diez, Nicholas Chancellor, Stephan Haas +2
We study the equilibration behavior following local quenches, using frustrated quantum spin chains as an example of interacting closed quantum systems. Specifically, we examine the…
