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 the…
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…
Superconductivity near two-dimensional Van Hove singularities: a determinant quantum Monte Carlo study
Gustav Romare, Daniel Shaffer, Alex Levchenko +2
The superconducting transition temperature of the two-dimensional attractive Hubbard model is computed in the vicinity of both ordinary (logarithmic) and higher-order (power-…
