Time-step targeting time-dependent and dynamical density matrix renormalization group algorithms with ab initio Hamiltonians
Enrico Ronca, Zhendong Li, Carlos A. Jimenez-Hoyos +1
We study the dynamical density matrix renormalization group (DDMRG) and time-dependent density matrix renormalization group (td-DMRG) algorithms in the ab initio context, to comput…

Spin-projected matrix product states (SP-MPS): a versatile tool for strongly correlated systems
Zhendong Li, Garnet Kin-Lic Chan
We present a new wavefunction ansatz that combines the strengths of spin projection with the language of matrix product states (MPS) and matrix product operators (MPO) as used in t…
