Thermal equilibrium and statistical thermometers in special relativity
(American Physical Society, 2007)
There is an intense debate in the recent literature about the correct generalization of Maxwell’s velocity distribution in special relativity. The most frequently discussed candidate distributions include the Jüttner ...

Very large stochastic resonance gains in finite sets of interacting identical subsystems driven by subthreshold rectangular pulses
(American Physical Society, 2007)
We study the phenomenon of nonlinear stochastic resonance (SR) in a complex noisy system formed by a finite number of interacting subunits driven by rectangular pulsed time periodic forces. We find that very large SR gains ...

Comment on “Markovian approximation in a coarse-grained description of atomic systems” [J. Chem. Phys.125, 204101 (2006)]
(American Institute of Physics, 2008)
The authors concluded that the coarse-graining dynamics of a one-dimensional chain of oscillators interacting through Lennard–Jones potentials is Markovian, in contrast with the situation observed for harmonic lattices. ...

Stochastic resonance with weak monochromatic driving: Gains above unity induced by high-frequency signals
(European Physical Society, 2007)
We study the effects of a high-frequency (HF) signal on the response of a noisy bistable system to a low-frequency subthreshold sinusoidal signal. We show that, by conveniently choosing the ratio of the amplitude of the ...
