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…
Metamagnetism in UTe2: the roles of itinerancy and localization
Theodore I. Weinberger, Daniel Shaffer, Zheyu Wu +12
The metamagnetic transition in UTe plays a key role in stabilizing two enigmatic field-induced superconducting phases. One of these phases (SC2) is truncated by the transition,…
Fluctuation-Induced Magnetoelectric Effect in Noncentrosymmetric Superconductors
Jaglul Hasan, Daniel Shaffer, Maxim Dzero +1
We study the effect of superconducting fluctuations on the spin susceptibility and NMR relaxation rate in noncentrosymmetric two-dimensional materials above the superconducting tra…
Electrically-controllable superconducting memory effect in UTe2
Zheyu Wu, Hanyi Chen, Mengmeng Long +13
If a computer could be assembled from superconducting components, the energy efficiency would far surpass that of conventional electronics. Historic research efforts towards this g…
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-…
Theories of Superconducting Diode Effects
Daniel Shaffer, Alex Levchenko
Superconducting diode effects (SDE), both in bulk superconductors and in Josephson junctions, have garnered a lot of attention due to potential applications in classical and quantu…
Helical phases and Bogoliubov Fermi surfaces probed by superconducting diode effects
Zekun Zhuang, Daniel Shaffer, Jaglul Hasan +1
Noncentrosymmetric superconductors (NCSs) with Rashba spin-orbit coupling (SOC) and in-plane magnetic fields have emerged as natural platforms for realizing both the bulk supercond…
Josephson Diode Effect from Nonequilibrium Current in a Superconducting Interferometer
Daniel Shaffer, Songci Li, Jaglul Hasan +2
We investigate the Josephson diode effect in a superconducting interferometer under nonequilibrium conditions. In contrast to its thermodynamic counterpart, which requires the simu…
Superconducting diode efficiency from singlet-triplet mixing in disordered systems
Jaglul Hasan, Daniel Shaffer, Maxim Khodas +1
The superconducting diode effect (SDE) -- the nonreciprocity of the critical current in a bulk superconductor -- has garnered significant attention due to its potential application…
Superconducting Diode Effect in Multiphase Superconductors
Daniel Shaffer, Dmitry V. Chichinadze, Alex Levchenko
We identify a new mechanism for the intrinsic superconducting diode effect (SDE) in multiphase superconductors. Using a Ginzburg-Landau and a microscopic two-band model, we find ph…
Supercurrent Diode Effect in Helical Superconductors
Jaglul Hasan, Daniel Shaffer, Maxim Khodas +1
In this work, we explore the generalities of the supercurrent diode effect. As an illustrative example, we examine a model of a two-dimensional superconductor with Rashba-type spin…
