Theory of anomalous Hall effect from screened vortex charge in a phase disordered superconductor
Jay D. Sau, Shuyang Wang
Motivated by recent experiments showing evidence for chiral superconductivity in an anomalous Hall phase of tetralayer graphene, we study the relation between the normal state anom…
Detection of Majorana zero modes bound to Josephson vortices in planar superconductor-topological insulator-superconductor junctions
Katharina Laubscher, Jay D. Sau
We study signatures of Majorana zero modes (MZMs) bound to Josephson vortices in superconductor-three-dimensional topological insulator-superconductor (S-TI-S) Josephson junctions…
Capacitance-based Fermion parity read-out and predicted Rabi oscillations in a Majorana nanowire
Jay D. Sau, Sankar Das Sarma
Recent experiments have measured flux dependent capacitance at radio frequencies leading to the potential for a fast parity read-out of a Majorana qubit. In this work we argue that…
Quantum hall transformer in a quantum point contact over the full range of transmission
Stuart Yi-Thomas, Jay D. Sau
A recent experiment [Cohen et al., Science 382, 542 (2023)] observed a robustly quantized conductance in a quantum point contact between fractional quantum Hall edges (a q…
Topologically protected emergent Fermi surface in an Abrikosov vortex lattice
Songyang Pu, Jay D. Sau, Rui-Xing Zhang
We show that a three-dimensional (3D) fully gapped type-II superconductor can feature emergent in-gap Fermi surfaces of Caroli-de Gennes Matricon (CdGM) quasiparticles in the prese…
Eliashberg theory for dynamical screening in bilayer exciton condensation
G. J. Sreejith, Jay D. Sau, Sankar Das Sarma
We study the effect of dynamical screening of interactions on the transition temperatures () of exciton condensation in a symmetric bilayer of quadratically dispersing electro…
Interaction robustness of the chiral anomaly in Weyl semimetals and Luttinger liquids from a mixed anomaly approach
Shuyang Wang, Jay D. Sau
The chiral anomaly is one of the robust quantum effects in relativistic field theories with a chiral symmetry where charges in chiral sectors appear to be separately conserved. The…
