Divergences in open quantum systems
Journal of High Energy Physics, 2018 We show that for cubic scalar field theories in five and more spacetime dimensions, and for the T = 0 limit of the Caldeira-Leggett model, the quantum master equation for long-wavelength modes initially unentangled from short-distance modes, and at ...

Quantum dynamics in open quantum-classical systems [PDF]
Journal of Physics: Condensed Matter, 2015 Often quantum systems are not isolated and interactions with their environments must be taken into account. In such open quantum systems these environmental interactions can lead to decoherence and dissipation, which have a marked influence on the properties of the quantum system.

Entanglement Degradation in Two Interacting Qubits Coupled to Dephasing Environments
Entropy, 2023 One of the main obstacles toward building efficient quantum computing systems is decoherence, where the inevitable interaction between the qubits and the surrounding environment leads to a vanishing entanglement.

Energy transport in open quantum systems [PDF]
, 2014 This thesis is concerned with modelling the dynamics of open quantum systems in several different contexts. Of principal interest is the manner in which the environment can modify, or even dominate, a system’s quantum behaviour in order to facilitate the

Transitionless quantum driving in open quantum systems
New Journal of Physics, 2014 We extend the concept of superadiabatic dynamics, or transitionless quantum driving, to quantum open systems whose evolution is governed by a master equation in the Lindblad form.

Krylov complexity in open quantum systems
Physical Review Research, 2023 Krylov complexity is a measure of operator complexity that exhibits universal behavior and bounds a large class of other measures. In this paper, we generalize Krylov complexity from a closed system to an open system coupled to a Markovian bath, where ...

Adaptive variational simulation for open quantum systems [PDF]
QuantumEmerging quantum hardware provides new possibilities for quantum simulation. While much of the research has focused on simulating closed quantum systems, the real-world quantum systems are mostly open.

Quantum localization in open chaotic systems [PDF]
Physical Review E, 2008 We study a quasi-Floquet state of a $δ$-kicked rotor with absorbing boundaries focusing on the nature of the dynamical localization in open quantum systems. The localization lengths $ξ$ of lossy quasi-Floquet states located near the absorbing boundaries decrease as they approach the boundary while the corresponding decay rates $Γ$ are dramatically ...

Local Spin and Open Quantum Systems: Clarifying Misconceptions, Unifying Approaches [PDF]
, 2020 We now show that Clark and Davidson local spins operators are perfectly defined subsystem operators if a fragment is taken as an open quantum system (OQS).
