A Further Comparison of MPS and TTNS for Nonadiabatic Dynamics of Exciton Dissociation
Weitang Li, Jiajun Ren, Jun Yan
Tensor networks, such as matrix product states (MPS) and tree tensor network states (TTNS), are powerful ansätze for simulating quantum dynamics. While both ansätze are theoretical…
Nonadiabatic Field: A Conceptually Novel Approach for Nonadiabatic Quantum Molecular Dynamics
Baihua Wu, Bingqi Li, Xin He +3
Reliable trajectory-based nonadiabatic quantum dynamics methods at the atomic level are critical for understanding many important processes in real systems. The paper reports lates…
Multi-set variational quantum dynamics algorithm for simulating nonadiabatic dynamics on quantum computers
Jingjing Li, Weitang Li, Xiaoxiao Xiao +4
Accelerating quantum dynamical simulations with quantum computing has received considerable attention but remains a significant challenge. In variational quantum algorithms for qua…
Improved Memory Truncation Scheme for Quasi-Adiabatic Propagator Path Integral via Influence Functional Renormalization
Limin Liu, Jiajun Ren, Weihai Fang
Accurately simulating non-Markovian quantum dynamics in system-bath coupled problems remains challenging. In this work, we present a novel memory truncation scheme for the iterativ…
Unified definition of exciton coherence length for exciton-phonon coupled molecular aggregates
Tong Jiang, Jiajun Ren, Zhigang Shuai
Exciton coherence length (ECL) is an essential concept to characterize the nature of exciton in molecular aggregates for photosynthesis, organic photovoltaics, and light-emitting d…
A General Automatic Method for Optimal Construction of Matrix Product Operators Using Bipartite Graph Theory
Jiajun Ren, Weitang Li, Tong Jiang +1
Constructing matrix product operators (MPO) is at the core of the modern density matrix renormalization group (DMRG) and its time dependent formulation. For DMRG to be conveniently…
