Engineering of many-body Majorana states in a topological insulator/s-wave superconductor heterostructure
Hsiang-Hsuan Hung, Jiansheng Wu, Kuei Sun +1
We study a vortex chain in a thin film of a topological insulator with proximity-induced superconductivity---a promising platform to realize Majorana zero modes (MZMs)---by modelin…
Multiple signatures of topological transitions for interacting fermions in chain lattices
Y. -H. Chan, Ching-Kai Chiu, Kuei Sun
We study one-component fermions in chain lattices with proximity-induced superconducting gap and interparticle short-range interaction, capable of hosting Majorana fermions. By sys…
Tuning between singlet, triplet, and mixed pairing states in an extended Hubbard chain
Kuei Sun, Ching-Kai Chiu, Hsiang-Hsuan Hung +1
We study spin-half fermions in a one-dimensional extended Hubbard chain at low filling. We identify three triplet and one singlet pairing channels in the system, which are independ…
Bose-Hubbard model with occupation-parity couplings
Kuei Sun, C. J. Bolech
We study a Bose-Hubbard model having on-site repulsion, nearest-neighbor tunneling, and ferromagneticlike coupling between occupation parities of nearest-neighbor sites. For a unif…
Transport in multi-terminal superconductor/ferromagnet junctions having spin-dependent interfaces
Kuei Sun, Nayana Shah, Smitha Vishveshwara
We study electronic transport in junctions consisting of a superconductor electrode and two ferromagnet (F) leads in which crossed Andreev reflections (CAR) and elastic cotunneling…
Anomalous polarization-dependent transport in nanoscale double-barrier superconductor/ferromagnet/superconductor junctions
Madalina Colci, Kuei Sun, Nayana Shah +2
We study the transport properties of nanoscale superconducting (S) devices in which two superconducting electrodes are bridged by two parallel ferromagnetic (F) wires, forming an S…
