Thermodynamics of Time Machines
arXiv:1302.3298
Abstract
In this note, a brief review of the consistent state approach to systems containing closed timelike curves or similar devices is given, and applied to the well known thermodynamic problem of Maxwell's demon. The 'third party paradox' for acausal systems is defined and applied to CTC censorship and black hole evaporation. Some traditional arguments for chronology protection are re-examined.
