Nagaoka supermetal in the particle-doped triangular Hubbard model
Rui Cao, Xiangyue Zhang, Hui Tan +4
While the interplay of correlations and geometric frustration in doped Mott insulators provides a fertile ground for exotic quantum phases, the nature of the metallic state emergin…

An Explicit Wavefunction of the Interacting Non-Hermitian Spin-1/2 1D System
Yue Wang, Xiangyu Zhang, Zhesen Yang +1
We present an explicit Bethe-ansatz wavefunction to a 1D spin- interacting fermion system, manifesting a many-body resonance resulting from the interplay between inter…

Quantum Phonon Dynamics Induced Spontaneous Spin-Orbit Coupling
Xiangyu Zhang, Da Wang, Congjun Wu
Spin-orbit coupling in solids is typically a single-body effect arising from relativity. In this work, we propose a spontaneous generation of spin-orbit coupling from symmetry brea…
