I examine the arguments which have been given for quantum fluctuation?dissipation theorems. I distinguish between a weak form of the theorem, which is true under rather general conditions, and a strong form which requires a Langevin equation for its statement. I argue that the latter has not been reliably derived in general. 
Conditions for the validity of the quantum Langevin equation.

This work bases its discussion on a direct, elementary treatment of Senitzky via a generalized Langevin equation as an intermediate step, and test this method by comparison with an exactly soluble model and point out its limitations. Expand
Under which conditions is quantum Brownian motion observable in a microscope
Abstract We investigate under which conditions we can expect to observe quantum Brownian motion in a microscope. Using the fluctuation–dissipation theorem, we investigate quantum Brownian motion inExpand
Brownian motion, quantum corrections and a generalization of the Hermite polynomials
The approximate nonequilibrium theory yields irreversible evolution of the Brownian particle towards thermal equilibrium with the ''heat bath'' and a new family of orthogonal polynomials which generalize the Hermite ones is introduced. Expand
Nonequilibrium quantum anharmonic oscillator and scalar field: high temperature approximations
We treat a relativistic quantum boson gas, described by a scalar quantum field, with quartic self-interaction (ϕ4) in three spatial dimensions: we review the known equilibrium case and present newExpand
Mapping fermion and boson systems onto the Fock space of harmonic oscillators.
It is shown that, whenever linear response theory applies, any generic bosonic or fermionic system at finite temperature T can be mapped onto a fictitious system of free-harmonic oscillators, the first time that such a mapping is explicitly worked out. Expand
We introduce a new model for dark energy in the Universe in which a small cosmological constant is generated by ordinary electromagnetic vacuum energy. The corresponding virtual photons exist at allExpand
Dark energy and Josephson junctions
It has been recently claimed that dark energy can be (and has been) observed in laboratory experiments by measuring the power spectrum SI(ω) of the noise current in a resistively shunted JosephsonExpand


On a quasiclassical Langevin equation
It is shown that the motion of a quantum mechanical particle coupled to a dissipative environment can be described by a Langevin equation where the stochastic force is generalized such that its powerExpand
In a quantum system damping and noise enter through the coupling with an external large bath. The usual treatments computes the density matrix of the system by expanding in the coupling strength toExpand
Irreversibility and Generalized Noise
A relation is obtained between the generalized resistance and the fluctuations of the generalized forces in linear dissipative systems. This relation forms the extension of the Nyquist relation forExpand
Dissipation in Quantum Mechanics. The Harmonic Oscillator
The need for a quantum-mechanical formalism for systems with dissipation which is applicable to the radiation field of a cavity is discussed. Two methods that have been used in this connection areExpand
Quantum noise in a current-biased Josephson junction
Quantum fluctuations in a current-biased Josephson junction, described in terms of the RCSJ model, are considered. The fluctuations of the voltage and phase across the junction are assumed to beExpand
Detection of quantum noise
We discuss the detection of quantum fluctuations in the light of the relationship between time-dependent correlators and measurable properties [L. Van Hove, Phys. Rev 95, 249 (1954)]. Considering theExpand
Electronic noise and fluctuations in solids
This book looks at the physics of electronic fluctuations (noise) in solids. The author emphasizes many fundamental experiments that have become classics: physical mechanisms of fluctuations, and theExpand
Could dark energy be measured in the lab
The experimentally measured spectral density of current noise in Josephson junctions provides direct evidence for the existence of zero-point fluctuations. Assuming that the total vacuum energyExpand
Measurements of quantum noise in resistively shunted Josephson junctions
Measurements have been made of the low-frequency spectral density of the voltage noise in current-biased resistively shunted Josephson tunnel junctions under conditions in which the noise mixed-downExpand
Fluctuation and Noise Letters
Parrondo’s paradox [1–4] shows that the combination of two losing strategies can lead to a winning result. The paradox can be phrased in terms of very simple gambling games in which some unit (say, 1Expand
