Quantum-geometry-driven Mott transitions and magnetism
Jixun K. Ding, Martin Claassen
Quantum geometry quantifies how the single-particle Bloch wavefunction changes in phase and amplitude across the Brillouin Zone. In multi-orbital systems where bands have strongly…

Enhanced superconducting correlations in the Emery model and its connections to strange metallic transport and normal state coherence
Sijia Zhao, Rong Zhang, Wen O. Wang +5
Numerical evidence for superconductivity in the single-band Hubbard model is elusive or ambiguous despite extensive study, raising the question of whether the single-band Hubbard m…

Intrinsic Thermal Hall Effect in Mott Insulators
Jixun K. Ding, Emily Z. Zhang, Wen O. Wang +4
In light of recent experimental data indicating a substantial thermal Hall effect in square lattice antiferromagnetic Mott insulators, we investigate whether a simple Mott insulato…
