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…
Inverse Faraday Effect in Rashba two-dimensional electron systems: interplay of spin and orbital effects
Jaglul Hasan, Chandan Setty
The inverse Faraday effect (IFE) refers to the generation of a DC magnetization by circularly polarized light through the transfer of optical angular momentum to electronic degrees…
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…
Resonant second harmonic generation in a two-dimensional electron system
Maxim Dzero, Jaglul Hasan, Alex Levchenko
We consider the nonlinear response of a disordered two-dimensional electronic system, lacking inversion symmetry, to an external alternating electric field. The application of an i…
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…
