Reducing Spatial and Temporal Dimensionality in the Multidimensional Caldeira-Leggett Model

Hongfei Zhan, Ernest W. Z. Pan, Zhenning Cai

The paper develops an efficient algorithm for simulating the real-time dynamics of the reduced density matrix in the multidimensional Caldeira‑Leggett model by using low‑rank spati…
