WebWe consider the problem of heat transport by vibrational modes between Langevin thermostats connected by a central device. The latter is anharmonic and can be subject to large temperature difference and thus be out of equilibrium. We develop a classical formalism based on the equation of motion method, the fluctuation–dissipation theorem … Web20 hours ago · April 13, 2024, 10:55 AM PDT. By Minyvonne Burke.
