Quantum-interference correction to conductivity in disordered electronic bands with non-uniform quantum geometry
Yip Chun Wong, Asimpunya Mitra, Yong Baek Kim
Weak localization in two-dimensional disordered electron systems originates from constructive interference between time-reversed scattering paths, giving rise to a logarithmically…
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…
Quantum Spin Liquids in Weak Mott Insulators with a Spin-Orbit Coupling
Asimpunya Mitra, Daniel J. Schultz, Yong Baek Kim
The weak Mott insulating regime of the triangular lattice Hubbard model exhibits a rich magnetic phase diagram as a result of the ring exchange interaction in the spin Hamiltonian.…
Quantum Fluctuations Suppress the Critical Fields in BaCo(AsO)
Shiva Safari, William Bateman-Hemphill, Asimpunya Mitra +10
Early efforts to realize exotic quantum ground states in frustrated magnets focused on frustration arising from the lattice geometry alone. Attention has shifted to bond-dependent…
Scalable simulation of non-equilibrium quantum dynamics via classically optimised unitary circuits
Luke Causer, Felix Jung, Asimpunya Mitra +2
The advent of near-term digital quantum computers could offer us an exciting opportunity to investigate quantum many-body phenomena beyond that of classical computing. To make the…
Magnon Interference Tunneling Spectroscopy as a Probe of 2D Magnetism
Asimpunya Mitra, Alberto Corticelli, Pedro Ribeiro +1
Probing two-dimensional single-layer quantum magnets remains a significant challenge. In this letter, we propose exploiting tunneling spectroscopy in the presence of magnetic impur…
