Umklapp scattering in the one-dimensional Hubbard model
Tong Liu, Kang Wang, Runze Chi +3
The Mott metal-insulator transition is a typical strong correlation effect triggered by the Umklapp scattering. However, in a physical system, the Umklapp scattering coexists with…

Spin Excitation Spectra of Anisotropic Spin- Triangular Lattice Heisenberg Antiferromagnets
Run-Ze Chi, Yang Liu, Yuan Wan +2
Investigation of dynamical excitations is difficult but crucial to the understanding of many exotic quantum phenomena discovered in quantum materials. This is particularly true for…
