The Prandtl-Tomlinson model of friction with stochastic driving
(IOP Publishing, 2018-01)
We consider the classical PrandtlTomlinson model of a particle moving on a corrugated potential, pulled by a spring. In the usual situation in which pulling acts at constant velocity γ, the model displays an average friction ...
Fluctuation-induced casimir forces in granular fluidsPHYSICAL REVIEW LETTERSPHYS REV LETT

Climate mediated exogenous forcing and synchrony in populations of the oak aphid in the UK.
(2009)
Contemporary population dynamics theory suggests that animal fluctuations in nature are the result of the combined forces of intrinsic and exogenous factors. Weather is the iconic example of an exogenous force. The common ...
Domain wall interactions due to vacuum Dirac field fluctuations in 2+1 dimensions
(American Physical Society, 2016-07-29)
We evaluate quantum effects due to a two-component Dirac field in 2+1 spacetime dimensions, coupled to domain-wall-like defects with a smooth shape. We show that these effects induce nontrivial contributions to the ...
Front depinning by deterministic and stochastic fluctuations: A comparison
(American Physical Society, 2019)
Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic ...
