PG - 221102 LID - 10.1063/5.0095961 [doi] AB - In this Communication, we propose the time-domain Prony fitting decomposition (t-PFD) as an accurate and efficient exponential series method, applicable to arbitrary bath correlation functions. The resulting numerical efficiency of hierarchical equations of motion (HEOM) formalism is greatly optimized, especially in low temperature regimes that would be inaccessible with other methods. For demonstration, we calibrate the present t-PFD against the celebrated Pade spectrum decomposition method, followed by converged HEOM evaluations on the single-impurity Anderson model system.
