Quantum trajectories and open many-body quantum systems [PDF]
, 2014 The study of open quantum systems has become increasingly important in the past years, as the ability to control quantum coherence on a single particle level has been developed in a wide variety of physical systems.

Analytical derivation of equilibrium state for open quantum system.
Journal of Chemical Physics, 2020 Calculation of the equilibrium state of an open quantum system interacting with a bath remains a challenge to this day, mostly due to a huge number of bath degrees of freedom.

Efficient calculation of open quantum system dynamics and time‐resolved spectroscopy with distributed memory HEOM (DM‐HEOM) [PDF]
Journal of Computational Chemistry, 2018 Time‐ and frequency‐resolved optical signals provide insights into the properties of light‐harvesting molecular complexes, including excitation energies, dipole strengths and orientations, as well as in the exciton energy flow through the complex.

Unification of witnessing initial system-environment correlations and witnessing non-Markovianity [PDF]
, 2012 We show the connection between a witness that detects dynamical maps with initial system-environment correlations and a witness that detects non-Markovian open quantum systems.

Krylov complexity in open quantum systems [PDF]
Physical Review Research, 2022 Krylov complexity is a novel measure of operator complexity that exhibits universal behavior and bounds a large class of other measures. In this letter, we generalize Krylov complexity from a closed system to an open system coupled to a Markovian bath ...

A study of quantum correlations in open quantum systems [PDF]
Quantum Information and Computation, 2011 In this work, we study quantum correlations in mixed states. The states studied are modeled by a two-qubit system interacting with its environment via a quantum non demolition (purely dephasing) as well as dissipative type of interaction. The entanglement dynamics of this two qubit system is analyzed.

Exact Open Quantum System Dynamics Using the Hierarchy of Pure States (HOPS). [PDF]
Journal of Chemical Theory and Computation, 2017 We show that the general and numerically exact Hierarchy of Pure States method (HOPS) is very well applicable to calculate the reduced dynamics of an open quantum system.

Non-Markovian Dynamics in Ultracold Rydberg Aggregates [PDF]
, 2016 We propose a setup of an open quantum system in which the environment can be tuned such that either Markovian or non-Markovian system dynamics can be achieved.

Signatures of Many-Body Localization in a Controlled Open Quantum System [PDF]
, 2016 In the presence of disorder, an interacting closed quantum system can undergo many-body localization (MBL) and fail to thermalize. However, over long times, even weak couplings to any thermal environment will necessarily thermalize the system and erase ...
