DESCRIPTION:The theory of stochastic thermodynamics connects the macroscop
 ic world of thermodynamics with the dynamical fluctuations that necessaril
 y occur on microscopic scales.  We examine the behaviour associated with l
 arge rare fluctuations in which systems violate ergodicity.  We show that 
 in systems with particular symmetries\, this can lead to peculiar steady s
 tates in which currents flow without dissipation [1\,2].  We also consider
  other examples of rare events that violate ergodicity\, focussing on simp
 le interacting-particle systems [3].\n\n[1] R. L. Jack and R. M. L. Evans\
