Harmonic Mixing

We investigate the problem of distributing a given amount of heat among three systems under the following conditions: The systems are able to exhibit negative Kelvin temperatures, and heat equalization always fulfills a harmonic mixing rule T = 2T(1) · T(2)/(T(1) + T(2)). Just this happens for spin systems in the high temperature approximation.
