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…
Electric field control of a quantum spin liquid in weak Mott insulators
Daniel J. Schultz, Alexandre Khoury, Félix Desrochers +3
The triangular lattice Hubbard model at strong coupling, whose effective spin model contains both Heisenberg and ring exchange interactions, exhibits a rich phase diagram as the ra…
Discovery of an odd-parity f-wave charge order in a kagome metal
Jiangchang Zheng, Caiyun Chen, Ruiqin Fu +13
The spontaneous breaking of symmetries is a cornerstone of physics, defining the phases of matter from the cosmological scale to the quantum realm. In condensed matter, electronic…
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.…
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…
