Evanescent-wave Johnson Noise from Superconductors

Hruday Mallubhotla, Gustav Romare, Ilya Esterlis +3

We compute the evanescent-wave Johnson noise (EWJN) in the vacuum half-space above a superconductor, and the resulting relaxation time () of spin and charge qubits placed at n…

Photogalvanic transport of nonreciprocal Cooper-pair fluctuations

Joaquim Telles de Miranda, Alex Levchenko

We develop a theory of the nonlinear optical and transport responses of two-dimensional noncentrosymmetric superconductors in the fluctuation regime above the transition temperatur…

Kinetic Lifshitz invariants and dynamics of nonreciprocal fluctuations in superconductors

Tony Liu, Joaquim Telles de Miranda, Daniel Shaffer +1

We derive the generalized time-dependent Ginzburg-Landau theory of a disordered noncentrosymmetric superconductor from the Keldysh nonlinear sigma model, using a two-dimensional el…

Probing nonlocal superconducting fluctuations with covariance noise magnetometry

Gustav Romare, Ilya Esterlis, Shimon Kolkowitz +1

The nonlocal superconducting fluctuation corrections to the conductivity tensor are calculated within the time-dependent Ginzburg-Landau framework, and their…

Anomalous Hall Effect Driven by Chiral Superconductivity

Alex Levchenko, Leonid Levitov

Direct dc-current signatures of unconventional superconductivity remain scarce. Existing probes of unconventional pairing are typically indirect, relying on phase-diagram anomalies…

Josephson current noise above Tc in superconducting tunnel junctions

Alex Levchenko

Tunnel junction between two superconductors is considered in the vicinity of the critical temperature. Superconductive fluctuations above Tc give rise to the noise of the ac Joseph…
