Negative charging energy in LaAlO/SrTiO quantum dots induced by SrTiO polarization
J. Czarnecki, A. Sierant, B. Szafran +12
We propose a microscopic mechanism for the negative charging energy in LaAlO/SrTiO quantum dots, arising from the electrostatic image charge associated with the paraelectri…
Local and nonlocal STM transport signatures of spin polarization in second order topological superconductors
Paweł Szumniak, Daniel Loss, Jelena Klinovaja
We investigate numerically the spin and transport properties of two-dimensional second-order topological superconductors (2D SOTSCs) hosting a pair of Majorana corner states (MCSs)…
Spin-resolved nonlocal transport in proximitized Rashba nanowires
Paweł Szumniak, Daniel Loss, Jelena Klinovaja
Non-equilibrium transport in hybrid semiconductor-superconductor nanowires is crucial for many quantum phenomena such as generating entangled states via cross Andreev reflection (C…
Helical and topological phase detection based on nonlocal conductance measurements in a three terminal junction
P. Wójcik, D. Sticlet, P. Szumniak +1
The helical state is a fundamental prerequisite for many spintronics applications and Majorana zero mode engineering in nanoscopic semiconductors. Its existence in quasi-one-dimens…
Spin-selective resonant tunneling induced by Rashba spin-orbit interaction in semiconductor nanowire
J. Pawłowski, G. Skowron, P. Szumniak +1
We consider a single electron confined within a quantum wire in a system of two electrostatically-induced QDs defined by nearby gates. The time-varying electric field, of single GH…
Hinge Modes and Surface States in Second-Order Topological Three-Dimensional Quantum Hall Systems induced by Charge Density Modulation
Paweł Szumniak, Daniel Loss, Jelena Klinovaja
We consider a system of weakly coupled one-dimensional wires forming a three-dimensional stack in the presence of a spatially periodic modulation of the chemical potential along th…
