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…
