The steady state fluctuation relation for the dissipation function

, 2007
We give a proof of transient fluctuation relations for the entropy production (dissipation function) in nonequilibrium systems, which is valid for most time reversible dynamics. We then consider the conditions under which a transient fluctuation relation

Spectrograph of Electric Field Fluctuation in Toroidal Helical Plasma [PDF]

, 2005
This is a report on fluctuation measurements using twin heavy ion beam probes in CHS. The observation shows that a dozen of coherent modes with intermittent nature coexist in an electron cyclotron heated plasma.

The Fluctuation Theorem

Advances in Physics, 2002
The question of how reversible microscopic equations of motion can lead to irreversible macroscopic behaviour has been one of the central issues in statistical mechanics for more than a century. The basic issues were known to Gibbs. Boltzmann conducted a very public debate with Loschmidt and others without a satisfactory resolution.

Fluctuation Scaling, Taylor’s Law, and Crime

, 2014
Fluctuation scaling relationships have been observed in a wide range of processes ranging from internet router traffic to measles cases. Taylor’s law is one such scaling relationship and has been widely applied in ecology to understand communities ...

Merits and qualms of work fluctuations in classical fluctuation theorems [PDF]

Physical Review E, 2017
Work is one of the most basic notion in statistical mechanics, with work fluctuation theorems being one central topic in nanoscale thermodynamics. With Hamiltonian chaos commonly thought to provide a foundation for classical statistical mechanics, here we present general salient results regarding how (classical) Hamiltonian chaos generically impacts on

Extension of the Fluctuation Theorem [PDF]

Physical Review Letters, 2003
Heat fluctuations are studied in a dissipative system with both mechanical and stochastic components for a simple model: a Brownian particle dragged through water by a moving potential. An extended stationary state fluctuation theorem is derived. For infinite time, this reduces to the conventional fluctuation theorem only for small fluctuations; for ...
