Fusion protocol for Majorana modes in coupled quantum dots
Chun-Xiao Liu, Haining Pan, F. Setiawan +2
In a recent breakthrough experiment [Nature (London) 614, 445 (2023)], signatures of Majorana zero modes have been observed in tunnel spectroscopy for a minimal Kitaev chain constr…
Electron-boson-interaction induced particle-hole symmetry breaking of conductance into subgap states in superconductors
F. Setiawan, Jay D. Sau
Particle-hole symmetry (PHS) of conductance into subgap states in superconductors is a fundamental consequence of a noninteracting mean-field theory of superconductivity. The break…
Electron temperature and tunnel coupling dependence of zero-bias and almost-zero-bias conductance peaks in Majorana nanowires
F. Setiawan, Chun-Xiao Liu, Jay D. Sau +1
A one-dimensional semiconductor nanowire proximitized by a nearby superconductor may become a topological superconductor hosting localized Majorana zero modes at the two wire ends…
Disorder-induced half-integer quantized conductance plateau in quantum anomalous Hall insulator-superconductor structures
Yingyi Huang, F. Setiawan, Jay D. Sau
A weak superconducting proximity effect in the vicinity of the topological transition of a quantum anomalous Hall system has been proposed as a venue to realize a topological super…
Phenomenology of soft gap, zero bias peak, and zero mode splitting in ideal Majorana nanowires
Chun-Xiao Liu, F. Setiawan, Jay D. Sau +1
We theoretically consider the observed soft gap in the proximity-induced superconducting state of semiconductor nanowires in the presence of spin-orbit coupling, Zeeman splitting,…
Transport in superconductor--normal metal--superconductor tunneling structures: Spinful p-wave and spin-orbit-coupled topological wires

We theoretically study transport properties of voltage-biased one-dimensional superconductor--normal metal--superconductor tunnel junctions with arbitrary junction transparency whe…
Conductance spectroscopy of nontopological-topological superconductor junctions
F. Setiawan, William S. Cole, Jay D. Sau +1
We calculate the zero-temperature differential conductance of a voltage-biased one-dimensional junction between a nontopological and a topological superconductor for arbitr…
Detecting topological superconductivity using low-frequency doubled Shapiro steps
Jay D. Sau, F. Setiawan
The fractional Josephson effect has been observed in many instances as a signature of a topological superconducting state containing zero-energy Majorana modes. We present a nontop…
Dynamical Detection of Topological Phase Transitions in Short-Lived Atomic Systems
F. Setiawan, K. Sengupta, I. B. Spielman +1
We demonstrate that dynamical probes provide direct means of detecting the topological phase transition (TPT) between conventional and topological phases, which would otherwise be…
Conductance spectroscopy of topological superconductor wire junctions
F. Setiawan, P. M. R. Brydon, Jay D. Sau +1
We study the zero-temperature transport properties of one-dimensional normal-superconductor (NS) junctions with topological superconductors across their topological transitions. Wo…
