Disentangling Majorana fermions from conventional zero energy states in semiconductor quantum wires
T. D. Stanescu, Sumanta Tewari
Majorana fermions (MFs) are predicted to occur as zero-energy bound states in semiconductor nanowire-superconductor structures. However, in the presence of disorder or smooth confi…
To close or not to close: the fate of the superconducting gap across the topological quantum phase transition in Majorana-carrying semiconductor nanowires
Tudor D. Stanescu, Sumanta Tewari, Jay D. Sau +1
We investigate theoretically the low energy physics of semiconductor Majorana wires in the vicinity of a magnetic field-driven topological quantum phase transition (TQPT). The loca…
Topological minigap in quasi-one-dimensional spin-orbit-coupled semiconductor Majorana wires
Sumanta Tewari, T. D. Stanescu, J. D. Sau +1
The excitation gap above the Majorana fermion (MF) modes at the ends of 1D topological superconducting (TS) semiconductor wires scales with the bulk quasiparticle gap E_{qp}. This…
Topological thermoelectric effects in spin-orbit coupled electron and hole doped semiconductors
E. Dumitrescu, Chuanwei Zhang, D. C. Marinescu +1
We compute the intrinsic contributions to the Berry-phase mediated anomalous Hall and Nernst effects in electron- and hole-doped semiconductors in the presence of an in-plane magne…
