DOI: 10.1021/acs.jctc.2c00851
Abstract: Quantum dynamics (QD) simulation is a powerful tool for interpreting ultrafast spectroscopy experiments and unraveling their microscopic mechanism in out-of-equilibrium excited state behaviors in various chemical, biological, and material systems. Although state-of-the-art numerical QD approaches… read more here.

DOI: 10.1038/s41598-017-01844-8
Abstract: To date, studies of the quantum Zeno and anti-Zeno effects focus on quantum systems that are weakly interacting with their environment. In this paper, we investigate what happens to a quantum system under the action… read more here.

Abstract: The structure of the initial system-environment state is fundamental to determining the nature and characteristics of the evolution of such an open quantum system. The usual assumption is to consider that the initial system-environment state… read more here.

DOI: 10.1103/physreva.96.022109
Abstract: We consider the dynamics of a collisional model in which both the system and environment are embodied by spin-$1/2$ particles. In order to include non-Markovian features in our model we introduce interactions among the environmental… read more here.

DOI: 10.1103/physreva.98.052344
Abstract: An evolution between a system and its environment which leads to pure dephasing of the system may either be a result of entanglement building up between the system and the environment or not (the second… read more here.

Dynamics of open quantum systems with initial system-environment correlations via stochastic unravelings
Sign Up to like & getrecommendations! Published in 2025 at "Physical Review A"
DOI: 10.1103/q353-4232
Abstract: In standard treatments of open quantum systems, the reduced dynamics is described starting from the assumption that the system and the environment are initially uncorrelated. This assumption, however, is not always guaranteed in realistic scenarios… read more here.
