Real-time Impurity Solver Using Grassmann Time-Evolving Matrix Product Operators
Ruofan Chen, Xiansong Xu, Chu Guo
An emergent and promising tensor-network-based impurity solver is to represent the path integral as a matrix product state, where the bath is analytically integrated out using Feyn…

Fidelity Out-of-Time-Order Correlator in the Spin-Boson Model
Ruofan Chen
In this article, using the numerically exact time-evolving matrix product operators method, we study the fidelity out-of-time-order correlator (FOTOC) in the unbiased spin-boson mo…
