Tensor network methods for non-perturbative dynamics of open quantum systems
Thibaut Lacroix, Adam Burgess, Nicola Lorenzoni +11
The description of open quantum system dynamics beyond the perturbative treatment (usually associated with Markovian master equations) is a computationally challenging task due to…
Factorization rule for multitime correlations in non-Markovian open quantum systems
Thomas K. Bracht, Moritz Cygorek
Experiments performed on quantum systems often measure multitime correlation functions. When quantum systems are weakly coupled to their environment, the time evolution of such cor…
Optical signatures of coherence in molecular dimers
Priyankar Banerjee, Adam Burgess, Julian Wiercinski +2
We calculate experimentally measurable signatures of quantum correlations in a coupled molecular dimer that strongly interacts with its vibrational environment. We investigate inte…
Fermionic versus Spin Baths in non-Interacting Transport Models
Muhammad Zia, Moritz Cygorek, Erik M. Gauger +1
We investigate how fermionic anticommutation shapes transport in a noninteracting resonant-level model where a single central site is coupled to an environment. To this end, we com…
Generation and manipulation of photon number wave packets in photonic cavities
Luca Nimmesgern, Moritz Cygorek, Doris E. Reiter +1
Quantum emitters inside optical cavities can create not only fixed photon number states but also photon number wave packets, which are states with a finite photon number distributi…
Time-nonlocal versus time-local long-time extrapolation of non-Markovian quantum dynamics
Moritz Cygorek, Erik M. Gauger
The high numerical demands for simulating non-Markovian open quantum systems motivate a line of research where short-time dynamical maps are extrapolated to predict long-time behav…
