Nonlocal conductance of a Majorana wire near the topological transition
Vladislav D. Kurilovich, William S. Cole, Roman M. Lutchyn +1
We develop a theory of the nonlocal conductance for a disordered Majorana wire tuned near the topological transition critical point. Under these conditions, the antisym…
Comment on Hess et al. Phys. Rev. Lett. {\bf 130}, 207001 (2023)
A. Antipov, W. Cole, K. Kalashnikov +5
In this comment, we show that the model introduced in Hess et al. Phys. Rev. Lett. {\bf 130}, 207001 (2023) fails the topological gap protocol (TGP) (Pikulin et al., arXiv:2103.122…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Topological superconductivity in nanowires proximate to a diffusive superconductor-magnetic insulator bilayer
Aleksei Khindanov, Jason Alicea, Patrick Lee +2
We study semiconductor nanowires coupled to a bilayer of a disordered superconductor and a magnetic insulator, motivated by recent experiments reporting possible Majorana-zero-mode…
Quasiparticle poisoning of Majorana qubits
Torsten Karzig, William S. Cole, Dmitry I. Pikulin
Qubits based on Majorana zero modes are a promising path towards topological quantum computing. Such qubits, though, are susceptible to quasiparticle poisoning which does not have…
Generic quantized zero-bias conductance peaks in superconductor-semiconductor hybrid structures
Haining Pan, William S. Cole, Jay D. Sau +1
We show theoretically that quantized zero-bias conductance peaks should be ubiquitous in superconductor-semiconductor hybrids by employing a zero-dimensional random matrix model wi…
Proposal for measuring the parity anomaly in a topological superconductor ring
Chun-Xiao Liu, William S. Cole, Jay D. Sau
A topological superconductor ring is uniquely characterized by a switch in the ground state fermion number parity upon insertion of one superconducting flux quantum - a direct cons…
Ising quantum criticality in Majorana nanowires
William S. Cole, Jay D. Sau, S. Das Sarma
Finite-length one-dimensional topological superconductor wires host localized Majorana zero modes at their ends. In realistic models, these appear only after a topological quantum…
Transport in superconductor--normal metal--superconductor tunneling structures: Spinful p-wave and spin-orbit-coupled topological wires
F. Setiawan, William S. Cole, Jay D. Sau +1
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…
