I examine the arguments which have been given for a quantum Langevin equation and a quantum fluctuation-dissipation relations. I argue that there is no reliable derivation of these relations beyond the simple (but important) case where all the equations of motion are linear.

We study the dynamics of two-dimensional surface gravity waves of fluid in a channel. The viscous dissipation in the bulk of the fluid is assumed to be negligible by comparing with the dissipation in the vicinity of the contact line. Capillarity effects are not considered. Dissipation in the vicinity of the contact line is described by contact line dissipation model suggested in de Ruijter et a...

The maxima of the scalar dissipation rate in turbulence appear in the form of sheets and correspond to the potentially most intensive scalar mixing events. Their cross section extension determines a locally varying diffusion scale of the mixing process and extends the classical Batchelor picture of one mean diffusion scale. The distribution of the local diffusion scales is analyzed for differen...

We study the pair production of open strings in constant external electric fields, using a general framework which encodes both relativistic string theory and generic linearly extended systems as well. In the relativistically invariant case we recover previous results, both for pair production and for the effective Born-Infeld action. We then derive a non-relativistic limit where the propagatio...

In this paper we consider the thermoelastic plate equation with localized thermal dissipation of memory type, proposed by Gurtin and Pipkin [3]. We will show that the solution of the corresponding model decays exponentially as time goes to infinity, provided the relaxation function decays exponentially. The mean difference with others thermoelastic system is that the whole system is of hyperbol...
