Bridging conformal field theory and parton approaches to SU(n)_k chiral spin liquids
Tong Liu, Ying-Hai Wu, Hong-Hao Tu +1
We employ the Wess-Zumino-Witten (WZW) model in conformal field theory to construct lattice wave functions in both one and two dimensions. The spins on all latti…

Efficient conversion from fermionic Gaussian states to matrix product states
Tong Liu, Ying-Hai Wu, Hong-Hao Tu +1
Fermionic Gaussian states are eigenstates of quadratic Hamiltonians and are widely used in quantum many-body problems. We propose a highly efficient algorithm that converts fermion…

Implementing advanced trial wave functions in fermion quantum Monte Carlo via stochastic sampling
Zhi-Yu Xiao, Zixiang Lu, Yixiao Chen +2
We introduce an efficient approach to implement correlated many-body trial wave functions in auxiliary-field quantum Monte Carlo (AFQMC). To control the sign/phase problem in AFQMC…
