Cluster Density Matrix Embedding Theory for Quantum Spin Systems
Zhuo Fan, Quanlin Jie
We applied cluster density matrix embedding theory, with some modifications, to a spin lattice system. The reduced density matrix of the impurity cluster is embedded in the bath st…

Parameterized excitation operators for coupled cluster method
Quanlin Jie
We present a coupled cluster method (CCM) with optimized excitation operators. The efficiency comes from a parameterized form of excitation operators. The parameters are found by v…

Approximating the ground state of fermion system by multiple determinant states: matching pursuit approach
Quanlin Jie
We present a simple and stable numerical method to approximate the ground state of a quantum many-body system by multiple determinant states. This method searches these determinant…
