Ising criticality can drive vortex deconfinement in a spin-orbit coupled Bose gas
Stuart Yi-Thomas, David M. Long, Jay D. Sau
Spin-orbit coupling in Bose gases is known to lead to an Ising-symmetry-broken phase where the bosons condense at one of two nonzero momenta. In two dimensions, the finite momentum…
Andreev spin qubits bound to Josephson vortices in spin-orbit coupled planar Josephson junctions
Katharina Laubscher, Valla Fatemi, Jay D. Sau
We propose a variant of Andreev spin qubits (ASQs) defined in planar Josephson junctions based on spin-orbit coupled two-dimensional electron gases (2DEGs) in a weak out-of-plane m…
Integer Quantum Hall Effect: Disorder, temperature, floating, and plateau width
Stuart Yi-Thomas, Yi Huang, Jay D. Sau +1
We theoretically consider disorder and temperature effects on the integer quantum Hall effect (IQHE) using a variety of distinct and complementary analytical and numerical techniqu…
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…
