Time crystallinity in open quantum systems [PDF]
Quantum, 2020 Time crystals are genuinely non-equilibrium quantum phases of matter that break time-translational symmetry. While in non-equilibrium closed systems time crystals have been experimentally realized, it remains an open question whether or not such a phase ...

QuTiP: An open-source Python framework for the dynamics of open quantum systems [PDF]
Computer Physics Communications, 2011 Article history: We present an object-oriented open-source framework for solving the dynamics of open quantum systems written in Python. Arbitrary Hamiltonians, including time-dependent systems, may be built up from operators and states defined by a ...

Exponentially Accelerated Approach to Stationarity in Markovian Open Quantum Systems through the Mpemba Effect. [PDF]
Physical Review Letters, 2021 Ergodicity breaking and slow relaxation are intriguing aspects of nonequilibrium dynamics both in classical and quantum settings. These phenomena are typically associated with phase transitions, e.g., the emergence of metastable regimes near a first ...

Identifiability of open quantum systems [PDF]
Physical Review A, 2014 We provide a general framework for the identification of open quantum systems. By looking at the input-output behavior, we try to identify the system inside a black box in which some Markovian time-evolution takes place. Due to the generally irreversible nature of the dynamics, it is difficult to assure full controllability over the system.

Operator Growth in Open Quantum Systems. [PDF]
Physical Review Letters, 2022 The spreading of quantum information in closed systems, often termed scrambling, is a hallmark of many-body quantum dynamics. In open systems, scrambling competes with noise, errors, and decoherence.

Using the Environment to Understand non-Markovian Open Quantum Systems [PDF]
Quantum, 2021 Tracing out the environmental degrees of freedom is a necessary procedure when simulating open quantum systems. While being an essential step in deriving a tractable master equation it represents a loss of information. In situations where there is strong

"What Is Life?" : Open Quantum Systems Approach
, 2022 Recently, the quantum formalism and methodology have been used in application to the modelling of information processing in biosystems, mainly to the process of decision making and psychological behaviour (but some applications in microbiology and ...

Floquet States in Open Quantum Systems [PDF]
Annual Review of Condensed Matter Physics, 2022 In Floquet engineering, periodic driving is used to realize novel phases of matter that are inaccessible in thermal equilibrium. For this purpose, the Floquet theory provides us a recipe for obtaining a static effective Hamiltonian.
