The customary treatments of diffusion-controlled reactions involve some approximate assumptions to reduce the problem to two molecules. It is possible, however, to set up the full hierarchy of equations for the distribution functions for all molecule

The standard way of describing noise in a quantum system consists in attaching to the system a reservoir or bath, which is assumed to be in thermal equilibrium. Subsequently the combined equation of motion is solved to second order in the interaction

In a quantum system damping and noise enter through the coupling with an external large bath. The usual treatments computes the density matrix of the system by expanding in the coupling strength to the bath and averaging over the bath. The result, ho

The problem of diffusion in a medium with non-uniform temperature was first considered by Landauer, and subsequently discussed by a number of authors. The conclusion is that there is no universal diffusion equation; rather its precise form depends on

The electric current through a membrane has been modelled as a transport process of single charged particles through a pore. In this way the average current and the spectral density of the current fluctuations were computed by Barkai et al. in terms

The behavior of a system in contact with a heat bath can be described either by a Langevin equation or by an equation for its density matrix. As both descriptions inevitably involve approximations, it is not evident that their results coincide. It is

The phenomenological approach to the Langevin equation breaks down for quantum systems. It is necessary to take into account explicitly an external bath, which causes the damping and fluctuations. The question then is whether there exists an autonomo
