Quantum Brownian motion for periodic coupling to an Ohmic bath
Abstract
We show theoretically how the periodic coupling between an engineered reservoir and a quantum Brownian particle leads to the formation of a dynamical steadystate which is characterized by an effective temperature above the temperature of the environment. The average steadystate energy of the system has a higher value than expected from the environmental properties. The system experiences repeatedly a nonMarkovian behavioras a consequence the corresponding effective decay for long evolution times is always on average stronger than the Markovian one. We also highlight the consequences of the scheme for the ZenoantiZeno crossover which depends, in addition to the periodicity {tau}, also on the total evolution time of the system.

The quantum Brownian motion paradigm provides a unified framework where one can see the interconnection of some basic quantum statistical processes such as decoherence, dissipation, particle creation, noise, and fluctuation. The present paper continues the investigation begun in earlier papers on the quantum Brownian motion in a general environment via the influence functional formalism. Here, the Brownian particle is coupled linearly to a bath of the most general timedependent quadratic oscillators. This bath of parametric oscillators minics a scalar field, while the motion of the Brownian particle modeled by a single oscillator could be used to depict the behavior ofmore »

KuboEinstein relation for quantum Brownian motion in a periodic potential
Using a previously derived general formalism for a dissipative quantum particle in a boson bath, the author proves that when the damping is Ohmic, the KuboEinstein relation between the diffusion constant and the linear mobility D = kTM holds to all orders in V{sub 0} for a periodic potential V(x) = V{sub 0}cos(k{sub 0}x). 
Quantum Brownian motion in a general environment. II. Nonlinear coupling and perturbative approach
We develop a perturbation scheme to treat the dynamics of a quantum Brownian particle (coordinate [ital x]) coupled nonlinearly to a bath of oscillators (coordinates [ital q][sub [ital n]]) with an interaction action in the form [lambda][ital f]([ital x])[ital q][sub [ital n]][sup [ital k]]. We derive the influence functionals for the [ital k]=2,3,4 cases to order [lambda][sup 2] and derive the master equations for the special cases of local dissipation and white noise, as well as the general cases of nonlocal dissipation and colored noise for [ital f]([ital x])=[ital x] and [ital x][sup 2]. We show that a generalized fluctuationdissipationmore » 
Effectiveeigenvalue approach to the nonlinear Langevin equation for the Brownian motion in a tilted periodic potential: Application to the Josephson tunneling junction
The effectiveeigenvalue method is used for a calculation of the impedance of the Josephson tunneling junction for an externally applied smallsignal alternating current in the presence of noise. The accuracy of the method is demonstrated by comparing the exact and approximate calculations. It shows clearly that the effectiveeigenvalue method yields a simple and concise analytical description of the solution of the problem under consideration. 
Motion of Brownian particles in a tilted periodic potential
The Langevin equation for a Brownian particle in a tilted periodic potential (TPP) with weak friction is reduced to two integral equations in energy variables. The dependence of the average velocity of the particle on the slope of the potential is found and a relationship is established between the expression obtained and the currentvoltage characteristic (IVC) of a concentrated Josephson junction.
