Chiral superconductors from parent states with nonuniform Berry curvature: Momentum-space vortices, Bogoliubov-de Gennes topology, and thermal Hall conductivity
L. David Le Nir, Asimpunya Mitra, Yong Baek Kim
We investigate chiral superconductivity emerging from parent electronic states with non-uniform Berry curvature, motivated by recent experiments in rhombohedral graphene multilayer…

Interplay of competing bond-order and loop-current fluctuations as a possible mechanism for superconductivity in kagome metals
Asimpunya Mitra, Daniel J. Schultz, Yong Baek Kim
The pairing symmetry and underlying mechanism for superconducting state of AVSb (A=K, Rb, Cs) kagome metal has been a topic of intense investigation. In this work, we c…

Superconductivity in kagome metals due to soft loop-current fluctuations
Daniel J. Schultz, Grgur Palle, Asimpunya Mitra +3
We demonstrate that soft fluctuations of translation symmetry-breaking loop currents provide a mechanism for unconventional superconductivity in kagome metals that naturally addres…
