It is well known that transport phenomena in condensed matter are strongly dependent on cooperative phenomena and that transport coefficients display anomaleous behavior near phase transitions. The general physical reason for this behavior is that transport coefficients can be expressed in terms of correlations of fluctuations in appropriate fields. Since these correlations decay slowly in time and get long ranged close to phase transitions it is expected that the the transport capacity will be strongly affected as the transition point is approached and the thermal density fluctuations blow up.

The course of this process can be subdivided into several steps, in which a series of resistances have to be overcome. The fraction of these individual resistances in the total resistance can be very different. First, as a result of flow (convective transport) and molecular motion (diffusion transport), the vapour reaches the phase interface. In the next step the vapour condenses at the phase interface, and finally the enthalpy of condensation released at the interface is transported to the cooled wall by conduction and convection. Accordingly, three resistances in series have to be overcome the thermal resistance in the vapour phase, the thermal resistance during the conversion of the vapour into the liquid phase, and finally the resistance to heat transport in the liquid phase.

The roots of QSM theory lie in Mori s statistical mechanical theory of transport processes and Kubo s theory of thermal disturbances. The version of QSM theory given here with its refinements and modem embellishments was used by the author to develop an irreversible thermodynamic theory for photophysical phenomena and a quantum stochastic Fokker-Planck theory for adiabatic and nona-diabatic processes in condensed phases.
