Beyond mean-field dynamics of the Dicke model with non-Markovian dephasing
Anqi Mu, Nathan Ng, Andrew J. Millis +1
We present a density matrix-based time dependent projection operator formalism to calculate the beyond mean-field dynamics of systems with non-Markovian local baths and one-to-all…

Tensor network influence functionals in the continuous-time limit: connections to quantum embedding, bath discretization, and higher-order time propagation
Gunhee Park, Nathan Ng, David R. Reichman +1
We describe two developments of tensor network influence functionals (in particular, influence functional matrix product states (IF-MPS)) for quantum impurity dynamics within the f…

Correlation Functions From Tensor Network Influence Functionals: The Case of the Spin-Boson Model
Haimi Nguyen, Nathan Ng, Lachlan P. Lindoy +4
We investigate the application of matrix product state (MPS) representations of the influence functionals (IF) for the calculation of real-time equilibrium correlation functions in…
