Thermally induced resonances in a three-body system including a solid surface.
Dispersion energy of a system out of equilibrium containing two molecules and substrate in different thermostats is calculated taking into account nonlocal optical effects. A resonance increase of energy due to three-body interaction in a system out of equilibrium is shown. In particular, dispersion energy of a two-body subsystem of the three-body system out of equilibrium may be essentially larger than the energy of the same subsystem in equilibrium. A necessary condition of the resonance increase is a closeness of eigenfrequencies of the subsystems composing the whole system. It is shown that different nonlocal reflectivities of surface corresponding to different additional boundary conditions lead to similar results in resonance magnification of dispersion interaction of subsystems in a system out of equilibrium.
