Non-Perturbative Renormalization Group Analysis of the Ohmic Quantum Dissipation
, 2003 We analyze quantum tunneling with the Ohmic dissipation by the non-perturbative renormalization group method. We calculate the localization susceptibility to evaluate the critical dissipation for the quantum-classical transition, and find considerably ...

On the concept of effective temperature in current carrying quantum critical states
, 2009 Quantum criticality has attracted considerable attention both theoretically and experimentally as a way to describe part of the phase diagram of strongly correlated systems.

Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations
Physical Review Research, 2020 The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the approach to equilibrium of closed quantum many-body systems. So far, however, experimental studies have focused on the relaxation dynamics of observables as described by ...

Entanglement generation between distant spins via quasilocal reservoir engineering
Physical Review Research, 2023 The generation and preservation of entanglement is a central goal in quantum technology. Traditionally, dissipation in quantum systems is thought to be detrimental to entanglement, however dissipation can also be utilized as a means of generating ...

Hierarchical theory of quantum dissipation: Partial fraction decomposition scheme [PDF]
, 2009 We propose a partial fraction decomposition scheme to the construction of hierarchical equations of motion theory for bosonic quantum dissipation systems.

, 1995 We address the question of the microscopic origin of dissipation in collective motion of a quantum many--body system in the framework of a parametric random matrix approach to the intrinsic dynamics. We show that the fluctuation--dissipation theorem is generally violated and, moreover, energy diffusion has a markedly non--Gaussian character and the ...

Efficient simulation of non-Markovian system-environment interaction
New Journal of Physics, 2016 In this work, we combine an established method for open quantum systems—the time evolving density matrix using orthogonal polynomials algorithm—with the transfer tensors formalism, a new tool for the analysis, compression and propagation of non-Markovian

Effects of a dissipative coupling to the momentum of a particle in a double well potential
Physical Review Research, 2020 Double well potentials offer the possibility of coherent state preparation and therefore constitute important building blocks in the analysis of quantum information and quantum engineering devices.

Mutual friction and diffusion of two-dimensional quantum vortices
Physical Review Research, 2023 Dissipation of quantum vortex motion is fundamental to superfluid dynamics and quantum turbulence, yet there is currently a large gap between theory and experiments with ultracold atoms.
