Abstract
Dynamics under which a system of Ising spins relaxes to a stationary state with Boltzmann–Gibbs measure and which do not fulfil the condition of detailed balance are irreversible and asymmetric. We revisit the problem of the determination of rates yielding such a stationary state for models with single-spin flip dynamics. We add some supplementary material to this study and confirm that Gibbsian irreversible Ising models exist for one- and two-dimensional lattices, but not for the three-dimensional cubic lattice. We also analyse asymmetric Gibbsian dynamics in the limit of infinite temperature. We finally revisit the case of a linear chain of spins under asymmetric conserved dynamics.
