Eliminating Infrared Divergences in the Pressure
I. T. Drummond, R. R. Horgan, P. V. Landshoff +1
The pressure of a system in thermal equilibrium is expressed as a mass integral over a sum of thermal propagators. This allows a Dyson resummation and is used to demonstrate that p…
Continuum Derrida Approach to Drift and Diffusivity in Random Media
D S Dean, I T Drummond, R R Horgan
By means of rather general arguments, based on an approach due to Derrida that makes use of samples of finite size, we analyse the effective diffusivity and drift tensors in certai…
Renormalization of Drift and Diffusivity in Random Gradient Flows
D. S. Dean, I. T. Drummond, R. R. Horgan
We investigate the relationship between the effective diffusivity and effective drift of a particle moving in a random medium. The velocity of the particle combines a white noise d…
