Reply to Comment on `Ratchet universality in the presence of thermal noise'

, 2013
The Comment by Quintero et al (arXiv:1309.1065[nlin.PS])does not dispute the central result of our paper [Phys. Rev. E {87}, 062114 (2013)] which is a theory explaining the interplay between thermal noise and symmetry breaking in the ratchet transport of

Fluctuation theorems: Work is not an observable [PDF]

, 2007
The characteristic function of the work performed by an external time-dependent force on a Hamiltonian quantum system is identified with the time-ordered correlation function of the exponentiated system's Hamiltonian. A similar expression is obtained for

The distribution of work performed on a NIS junction

New Journal of Physics, 2016
We propose an experimental setup to measure the work performed in a normal-metal/insulator/superconducting (NIS) junction, subjected to a voltage change and in contact with a thermal bath.

Randomly Amplified Discrete Langevin Systems

, 1999
A discrete stochastic process involving random amplification with additive noise is studied analytically. If the non-negative random amplification factor $b$ is such that $=1$ where $\beta$ is any positive non-integer, then the steady state probability ...

Driving particle current through narrow channels using classical pump [PDF]

, 2007
We study a symmetric exclusion process in which the hopping rates at two chosen adjacent sites vary periodically in time and have a relative phase difference. This mimics a colloidal suspension subjected to external space and time dependent modulation of

Comment on ''Measurement of Effective Temperatures in an Aging Colloidal Glass'' [PDF]

, 2007
We measure the fluctuations of the position of a silica bead trapped by an optical tweezers during the aging of a Laponite suspension.

Comment on "Generalized exclusion processes: Transport coefficients"

, 2016
In a recent paper Arita et al. [Phys. Rev. E 90, 052108 (2014)] consider the transport properties of a class of generalized exclusion processes. Analytical expressions for the transport-diffusion coefficient are derived by ignoring correlations.

Avalanches in the Weakly Driven Frenkel-Kontorova Model

, 1994
A damped chain of particles with harmonic nearest-neighbor interactions in a spatially periodic, piecewise harmonic potential (Frenkel-Kontorova model) is studied numerically.

Light Cone analysis of relativistic first-order in the gradients hydrodynamics

, 2010
This work applies a Rayleigh-Brillouin light spectrum analysis in order to establish a causality test by means of a frequency cone. This technique allows to identify forbidden and unforbidden regions in light scattering experiments and establishes if a ...

Renormalisation of out-of-equilibrium quantum fields

, 2008
We consider the initial value problem and its renormalisation in the framework of the two-particle-irreducible (2PI) effective action. We argue that in the case of appropriately chosen self-consistent initial conditions, the counterterms needed to ...
