Anomaly in Open Quantum Systems and its Implications on Mixed-State Quantum Phases [PDF]
PRX QuantumIn this paper, we develop a systematic approach to characterize the ′t Hooft anomaly in open quantum systems. Owing to nontrivial couplings to the environment, symmetries in such systems manifest as either strong or weak type.

Effective-Hamiltonian Theory of Open Quantum Systems at Strong Coupling [PDF]
PRX Quantum, 2022 We present the reaction-coordinate polaron-transform (RCPT) framework for generating effective Hamiltonian models to treat nonequilibrium open quantum systems at strong coupling with their surroundings.

Mpemba effects in nonequilibrium open quantum systems [PDF]
Physical Review ResearchThe Mpemba effect was originally referred to as the faster icing of a higher-temperature system than a lower-temperature system, and was later generalized to anomalous decays of both classical and quantum observables to equilibrium states.

Simulation of open quantum systems by automated compression of arbitrary environments [PDF]
Nature Physics, 2021 Studies of the dynamics of open quantum systems are limited by the large Hilbert space of typical environments, which is too large to be treated exactly.

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.

Quantum Simulation of Open Quantum Systems Using a Unitary Decomposition of Operators. [PDF]
Physical Review Letters, 2021 Electron transport in realistic physical and chemical systems often involves the nontrivial exchange of energy with a large environment, requiring the definition and treatment of open quantum systems.

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.

Designing open quantum systems with known steady states: Davies generators and beyond [PDF]
QuantumWe provide a systematic framework for constructing generic models of nonequilibrium quantum dynamics with a target stationary (mixed) state. Our framework identifies (almost) all combinations of Hamiltonian and dissipative dynamics that relax to a steady
