Heat fluctuations in Ising models coupled with two different heat baths
Date of Issue2008
School of Physical and Mathematical Sciences
Monte Carlo simulations of Ising models coupled to heat baths at two different temperatures are used to study a fluctuation relation for the heat exchanged between the two thermostats in a time τ. Different kinetics (single-spin-flip or spin-exchange Kawasaki dynamics), transition rates (Glauber or Metropolis), and couplings between the system and the thermostats have been considered. In every case the fluctuation relation is verified in the large τ limit, both in the disordered and in the low temperature phase. Finite-τ corrections are shown to obey a scaling behavior.
