Stable quantum-correlated many-body states through engineered dissipation
Science, 2023Engineered dissipative reservoirs have the potential to steer many-body quantum systems toward correlated steady states useful for quantum simulation of high-temperature superconductivity or quantum magnetism.

Liouvillian-gap analysis of open quantum many-body systems in the weak dissipation limit
Physical review B, 2023Recent experiments have reported that novel physics emerge in open quantum many-body sys- tems due to an interplay of interactions and dissipation, which stimulate theoretical studies of the many-body Lindblad equation.

Quantum Probability and Infinite Dimensional Analysis, 2010
In the evolution of a quantum system subject to a nonlinear dissipative term of Kostin type the probability amplitudes associated to excited states of the Hamiltonian are damped; this results in a dynamic convergence toward the ground state. In this paper we dicuss how dissipation can replace adiabatic evolution in the search of the ground state of a ...

Quantum reflection and dissipation
Physical Review B, 1987The effect of dissipation on quantum reflection is treated in the weak-coupling limit. For high incident energies, dissipation suppresses quantum reflection. Surprisingly, for intermediate incident energies, the reflection rate is greatly enhanced because of energy fluctuations. The reflection rate increases with temperature as exp(${T}^{n}$), with the

Finite-Time Quantum Dissipation Engineering
ICC 2025 - IEEE International Conference on CommunicationsQDE is an emerging paradigm in which an ancillary quantum system is used to remove entropy from a primary quantum system of interest. As a means for entropy reduction, quantum dissipation engineering (QDE) is useful across the domains of quantum sensing,

Physica Scripta, 1987
Summary: A report is presented on recent work on chaos and the onset of chaos in dissipative quantized systems described by discrete maps. The method of quantization of such maps is described, and the formulation of the quantized maps -- conservative or dissipative -- in terms of `quasistochastic' \(c\)-number maps explained.

Imaging work and dissipation in the quantum Hall state in graphene
Nature, 2019Topology is a powerful recent concept asserting that quantum states could be globally protected against local perturbations1,2. Dissipationless topologically protected states are therefore of major fundamental interest as well as of practical importance ...

The talk reviews some recent developments in the theory of quantum mechanical tunneling. The new phenomena discussed arise from the coupling of the tunneling system to a heat bath of temperature T. The question is how dissipation and thermal fluctuation affect the tunneling rate.
