Nature of the zero-bias conductance peak associated with Majorana bound states in topological phases of semiconductor-superconductor hybrid structures
Dibyendu Roy, C. J. Bolech, Nayana Shah
Rashba spin-orbit coupled semiconductor-superconductor hybrid structures in the presence of Zeeman splitting have emerged as the first experimentally realizable topological superco…
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…
Cratered Lorentzian response of driven microwave superconducting nanowire-bridged resonators: oscillatory and magnetic-field induced stochastic states
Matthew W. Brenner, Sarang Gopalakrishnan, Jaseung Ku +5
Microwave Fabry-Perot resonators containing nonlinear mesoscopic elements (such as superconducting nanowires) can be used to explore many-body circuit QED. Here, we report on obser…
Stochastic dynamics of phase-slip trains and superconductive-resistive switching in current-biased nanowires
David Pekker, Nayana Shah, Mitrabhanu Sahu +2
Superconducting nanowires fabricated via carbon-nanotube-templating can be used to realize and study quasi-one-dimensional superconductors. However, measurement of the linear resis…
Probing individual topological tunnelling events of a quantum field via their macroscopic consequences
Mitrabhanu Sahu, Myung-Ho Bae, Andrey Rogachev +5
Phase slips are topological fluctuation events that carry the superconducting order-parameter field between distinct current carrying states. Owing to these phase slips low-dimensi…
Inherent stochasticity of superconductive-resistive switching in nanowires
Nayana Shah, David Pekker, Paul M. Goldbart
Hysteresis in the current-voltage characteristic in a superconducting nanowire reflects an underlying bistability. As the current is ramped up repeatedly, the state switches from a…
Universal thermal and electrical transport near the superconductor-metal quantum phase transition in nanowires
Adrian del Maestro, Bernd Rosenow, Nayana Shah +1
We describe the thermal and electrical conductivities of quasi-one dimensional wires, across a quantum phase transition from a superconductor to a metal induced by pairbreaking per…
Low temperature magnetoresistance of dirty thin films and quantum wires near a parallel-field-tuned superconducting quantum phase transition
N. Shah, A. V. Lopatin, V. M. Vinokur
We study the low temperature magnetoresistance of dirty thin films and quantum wires close to a quantum phase transition from a superconducting to normal state, induced by applying…
Fluctuation conductivity of thin films and nanowires near a parallel-field-tuned superconducting quantum phase transition
A. V. Lopatin, N. Shah, V. M. Vinokur
We calculate the fluctuation correction to the normal state conductivity in the vicinity of a quantum phase transition from a superconducting to normal state, induced by applying a…
