Reduced density matrix hybrid approach: Application to electronic energy transfer
Timothy C. Berkelbach, Thomas E. Markland, David R. Reichman
Electronic energy transfer in the condensed phase, such as that occurring in photosynthetic complexes, frequently occurs in regimes where the energy scales of the system and enviro…
Reduced density matrix hybrid approach: An efficient and accurate method for adiabatic and non-adiabatic quantum dynamics
Timothy C. Berkelbach, David R. Reichman, Thomas E. Markland
We present a new approach to calculate real-time quantum dynamics in complex systems. The formalism is based on the partitioning of a system's environment into "core" and "reservoi…
Quantum quench spectroscopy of a Luttinger liquid: Ultrarelativistic density wave dynamics due to fractionalization in an XXZ chain
Matthew S. Foster, Timothy C. Berkelbach, David R. Reichman +1
We compute the dynamics of localized excitations produced by a quantum quench in the spin 1/2 XXZ chain. Using numerics combining the density matrix renormalization group and exact…
