Unconventional incommensurate epitaxy of superconducting FeSe films on SrTiO
M. Klement, K. M. Fijalkowski, M. Kamp +2
We present a combined X-ray diffraction and transmission electron microscopy study of superconducting FeSe/FeTe multilayers grown by molecular beam epitaxy on SrTiO(001) substr…
Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Self-Consistent Model for Gate Control of Narrow-, Broken-, and Inverted-Gap (Topological) Heterostructures
Maximilian Hofer, Christopher Fuchs, Moritz Siebert +8
Even small electrostatic potentials can dramatically influence the band structure of narrow-, broken-, and inverted-gap materials. A quantitative understanding often necessitates a…
Wiedemann-Franz behavior at the Weyl points in compressively strained HgTe
Abu Alex Aravindnath, Yi-Ju Ho, Fabian Schmitt +6
Weyl semimetals, with their unique electronic band structure, have drawn significant interest for their potential to explore quantum anomalies in condensed matter systems. In this…
Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
Zero external magnetic field quantum standard of resistance at the 10-9 level
D. K. Patel, K. M. Fijalkowski, M. Kruskopf +10
The quantum anomalous Hall effect holds promise as a disruptive innovation in condensed matter physics and metrology, as it gives access to Hall resistance quantization in terms of…
