Braid group and topological phase transitions in nonequilibrium stochastic dynamics.
We show that distinct topological phases of the band structure of a non-Hermitian Hamiltonian can be classified with elements of the braid group. As the proof of principle, we consider the non-Hermitian evolution of the statistics of nonequilibrium stochastic currents. We show that topologically nontrivial phases have detectable properties, including the emergence of decaying oscillations of pa...
متن کاملNonequilibrium phase transitions in models of adsorption and desorption.
The nonequilibrium phase transition in a system of diffusing, coagulating particles in the presence of a steady input and evaporation of particles is studied. The system undergoes a transition from a phase in which the average number of particles is finite to one in which it grows linearly in time. The exponents characterizing the mass distribution near the critical point are calculated in all ...
متن کاملPerturbative nonequilibrium dynamics of phase transitions in an expanding universe
It has long been apparent that the hot, dense matter present in the early universe might undergo a variety of phase transitions [1]. In particular, the “new inflation” scenario of Linde [2] and Albrecht and Steinhardt [3] (modifying an earlier proposal of Guth [4]) suggests that a symmetry-breaking phase transition at the GUT scale would lead to a period of quasi-exponential expansion, perhaps ...
متن کاملPhase Transitions in Nonequilibrium Systems
Collective phenomena in systems far from thermal equilibrium have been a subject of extensive studies in recent years. Usually these systems are driven out of equilibrium by external fields, such as electric field in the case of conductors, pressure gradient in the case of fluids, temperature gradient in the case of heat conductors, chemical potential gradient in the case of growth problems and...
متن کاملZero-range processes: prototypical stochastic models with slow dynamics and nonequilibrium phase transitions
Everyday life and recent experiments suggest that a thermodynamical description of granular media might be feasible. Given that granular media consist of a large number of grains, there is a strong motivation for providing a statistical ground to this hypothetic thermodynamical description. It has been argued by Edwards and collaborators that the dynamics is controled by the mechanically stable...
