Dissipative quantum metrology in manybody systems of identical particles
New Journal of Physics, 2014 Estimation of physical parameters is essential in almost any part of science and technology. The enhancement of performance in this task (e.g. beating the standard classical shot-noise limit) using available physical resources is a major goal in ...

Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos
PRX Quantum, 2023 We develop a theory of symmetry in open quantum systems. Using the operator-state mapping, we characterize symmetry of Liouvillian superoperators for the open quantum dynamics by symmetry of operators in the double Hilbert space and apply the 38-fold ...

Quantum ratchets in dissipative chaotic systems [PDF]
Physical Review Letters, 2005 Using the method of quantum trajectories we study a quantum chaotic dissipative ratchet appearing for particles in a pulsed asymmetric potential in the presence of a dissipative environment. The system is characterized by directed transport emerging from

Phase Diffusion in Quantum Dissipative Systems [PDF]
Physical Review A, 2007 We study the dynamics of the quantum phase distribution associated with the reduced density matrix of a system for a number of situations of practical importance, as the system evolves under the influence of its environment, interacting via a quantum ...

Dissipation induced localization-delocalization transition in flat band systems [PDF]
iScienceSummary: The interplay between dissipation and localization in quantum systems has garnered significant attention due to its potential to manipulate transport properties and induce phase transitions.

Quantum current in dissipative systems
New Journal of Physics, 2019 Describing current in open quantum systems can be problematic due to the subtle interplay of quantum coherence and environmental noise. Probing the noise-induced current can be detrimental to the tunneling-induced current and vice versa.

Physical Review Research, 2020 We study the quantum dynamics of many-body systems, in the presence of dissipation due to the interaction with the environment, under Kibble-Zurek (KZ) protocols in which one Hamiltonian parameter is slowly, and linearly in time, driven across the ...

From Geometry to Coherent Dissipative Dynamics in Quantum Mechanics
Quantum Reports, 2021 Starting from the geometric description of quantum systems, we propose a novel approach to time-independent dissipative quantum processes according to which energy is dissipated but the coherence of the states is preserved.

Quantum Nonreciprocal Interactions via Dissipative Gauge Symmetry
PRX Quantum, 2023 One-way nonreciprocal interactions between two quantum systems are typically described by a cascaded quantum master equation, and rely on an effective breaking of time-reversal symmetry (TRS) as well as the balancing of coherent and dissipative ...

Dissipative Properties of Quantum Systems [PDF]
Proceedings of the National Academy of Sciences, 1972 We consider the dissipative properties of large quantum systems from the point of view of kinetic theory. The existence of a nontrivial collision operator imposes restrictions on the possible collisional invariants of the system. We consider a model in which a discrete level is coupled to a set of quantum states and which, in the limit of a large ...
