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…
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…
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 for dissipative time crystals in coupled parametric oscillators
Stuart Yi-Thomas, Jay D. Sau
Discrete time crystals are novel phases of matter that break the discrete time translational symmetry of a periodically driven system. In this work, we propose a classical system o…
