Superconducting Berry Curvature Dipole
Oles Matsyshyn, Giovanni Vignale, Justin C. W. Song
Superconductivity and Bloch band Berry curvature responses represent two distinct paradigms of quantum coherent phenomena. The former relies on the collective motion of Cooper pair…
Kramers Dichroism in PT Symmetric Magnets
Oles Matsyshyn, Ying Xiong, Justin C. W. Song
Superpositions between states in doubly degenerate Kramers pairs can act as an internal degree of freedom. Here we uncover a Kramers dichroism in PT symmetric magnets: interband tr…
High-Temperature Quantum Oscillations of a Non-equilibrium Non-Fermi Liquid
Oles Matsyshyn, Li-kun Shi, Inti Sodemann Villadiego
A periodically driven Fermi gas coupled to a simple boson bath reaches a non-equilibrium steady-state occupation with sharp non-analyticities at certain momenta. Here, we demonstra…
Nonequilibrium Exchange Nonlinear Hall Effect
John Tan, Oles Matsyshyn, Giovanni Vignale +1
Quantum geometric electronic responses are often viewed through a non-interacting lens: independent quasiparticles accumulate Berry phases as they move through a static crystal and…
Superconducting Photocurrent and Light Enriched Supercurrent Phase Relation
Oles Matsyshyn, Justin C. W. Song
Noncentrosymmetric superconductors are expected to exhibit DC photocurrents even for irradiation frequencies below the superconducting gap. Such superconducting photocurrent are no…
Ultra-critical Floquet Non-Fermi Liquid
Li-kun Shi, Oles Matsyshyn, Justin C. W. Song +1
We demonstrate that periodically driven Fermions coupled to simple bosonic baths have steady state occupations of Floquet Bloch bands that generically display non-analyticties at c…
