Chiral and topological superconductivity in isospin polarized multilayer graphene
Max Geier, Margarita Davydova, Liang Fu
A microscopic mechanism for chiral p-wave superconductivity from Coulomb repulsion is proposed for spin- and valley-polarized state of rhombohedral multilayer graphene. The superco…
Nonreciprocal superconductivity
Margarita Davydova, Max Geier, Liang Fu
We introduce the notion of nonreciprocal superconductors where inversion and time-reversal symmetries are broken, giving rise to an asymmetric energy dispersion. We demonstrate tha…
Ubiquitous Superconducting Diode Effect in Superconductor Thin Films
Yasen Hou, Fabrizio Nichele, Hang Chi +13
The macroscopic coherence in superconductors supports dissipationless supercurrents which could play a central role in emerging quantum technologies. Accomplishing unequal supercur…
Universal Josephson diode effect
Margarita Davydova, Saranesh Prembabu, Liang Fu
We propose a universal mechanism for the Josephson diode effect in short Josephson junctions. The proposed mechanism is due to finite Cooper pair momentum and is a manifestation of…
Josephson diode effect from Cooper pair momentum in a topological semimetal
Banabir Pal1, Anirban Chakraborty, Pranava K. Sivakumar +11
In the presence of an external magnetic field Cooper pairs in noncentrosymmetric superconductors can acquire finite momentum. Recent theory predicts that such finite-momentum pairi…
