The Green's function Monte Carlo combined with projected entangled pair state approach to the frustrated - Heisenberg model
He-Yu Lin, Yibin Guo, Rong-Qiang He +2
The tensor network algorithm, a family of prevalent numerical methods for quantum many-body problems, aptly captures the entanglement properties intrinsic to quantum systems, enabl…
Natural orbitals renormalization group approach to a spin-1/2 impurity interacting with two helical liquids
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Using the natural orbitals renormalization group, we studied the problem of a localized spin- 1/2 impurity coupled to two helical liquids via the Kondo interaction in a quantum spi…
Characterizing Many-Body Localization by Out-of-Time-Ordered Correlation
Rong-Qiang He, Zhong-Yi Lu
The out-of-time-ordered (OTO) correlation is a key quantity for quantifying quantum chaoticity and has been recently used in the investigation of quantum holography. Here we use it…
Natural Orbitals Renormalization Group Approach to the Two-Impurity Kondo Critical Point
Rong-Qiang He, Jianhui Dai, Zhong-Yi Lu
The problem of two magnetic impurities in a normal metal exposes the two opposite tendencies in the formation of a singlet ground state, driven respectively by the single-ion Kondo…
Direct observation of fragile Mott insulators on plaquette Hubbard lattices
Han-Qing Wu, Rong-Qiang He, Zi Yang Meng +1
Employing extensive cellular dynamical mean-field theory (CDMFT) calculations with exact diagonalization impurity solver, we investigate the ground state phase diagrams and non-mag…
