Quest for topological superconductivity at superconductor-semiconductor interfaces
S. M. Frolov, M. J. Manfra, J. D. Sau
We analyze the evidence of Majorana zero modes in nanowires that came from tunneling spectroscopy and other experiments, and scout the path to topologically protected states that a…
Non-equilibrium nature of non-linear optical response: Application to the bulk photo voltaic effect
Tamoghna Barik, Jay D. Sau
The bulk photovoltaic effect is an example of a non-linear optical response that leads to a DC current that is relevant for photo-voltaic applications. In this work, we theoretical…
Ferromagnetism and its stability from the one-magnon spectrum in twisted bilayer graphene
Yahya Alavirad, Jay D. Sau
We study ferromagnetism and its stability in twisted bilayer graphene. We work with a Hubbard-like interaction that corresponds to the screened Coulomb interaction in a well-define…
Symmetry-breaking signatures of multiple Majorana zero modes in one-dimensional spin-triplet superconductors
Arnab Barman Ray, Jay D. Sau, Ipsita Mandal
We study the effects of various symmetry-breaking perturbations on the experimentally measurable signatures (such as conductance and Josephson response) of quasi-one-dimensional (q…
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…
Scheme for Majorana Manipulation Using Magnetic Force Microscopy
Benjamin H. November, Jay D. Sau, James R. Williams +1
We propose a scheme for the use of magnetic force microscopy to manipulate Majorana zero modes emergent in vortex cores of topological superconductors in the Fe(Se,Te) family. We c…
