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…
Two-dimensional coherent spectrum of interacting spinons from matrix-product states
Qi Gao, Yang Liu, Haijun Liao +1
We compute numerically the second and third order nonlinear magnetic susceptibilities of an Ising ladder model in the context of two-dimensional coherent spectroscopy by using the…
Projected d-wave superconducting state: a fermionic projected entangled pair state study
Qi Yang, Xing-Yu Zhang, Hai-Jun Liao +2
We investigate the physics of projected d-wave pairing states using their fermionic projected entangled pair state (fPEPS) representation. First, we approximate a d-wave Bardeen-Co…
Variational determination of arbitrarily many eigenpairs in one quantum circuit
Guanglei Xu, Yi-Bin Guo, Xuan Li +3
The state-of-the-art quantum computing hardware has entered the noisy intermediate-scale quantum (NISQ) era. Having been constrained by the limited number of qubits and shallow cir…
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…
