Query: On the logarithmic oscillator as a thermostat   Campisi, Zhan, Talkner and H\"anggi have recently proposed [Campisi] the use
of the logarithmic oscillator as an ideal Hamiltonian thermostat, both in
simulations and actual experiments. However, the system exhibits several
theoretical drawbacks which must be addressed if this thermostat is to be
implemented effectively.
