Emergence from irreversibility

Doing time. The emergence of irreversibility

By considering an enterprise to be a system of agents that observe and construct theories about themselves immediately raises issues of closure. These in turn pose questions about the identity and evolution of that which is exhibiting such closure. We address these questions by assigning enterprises to a class of systems whose models are triply articulated. The existential articulation provides...

Irreversibility temperature from magnetic relaxation

Simulation of the magnetic relaxation in a model of hard superconductor reveals a new time scale below the irreversibility temperature. The relaxation in this new time scale, which appears in an intermediate time window, is a power law and is related to self organization of the magnetic flux around the critical current density Jc during the relaxation. Emergence of a new time scale which along ...

Irreversibility and Dephasing from Vacuum Fluctuations

Thermodynamic Irreversibility from high-dimensional Hamiltonian Chaos

This paper discusses the thermodynamic irreversibility realized in high-dimensional Hamiltonian systems with a time-dependent parameter. A new quantity, the irreversible information loss, is defined from the Lyapunov analysis so as to characterize the thermodynamic irreversibility. It is proved that this new quantity satisfies an inequality associated with the second law of thermodynamics. Base...

From Coupled Dynamical Systems to Biological Irreversibility

In the first half of the paper, some recent advances in coupled dynamical systems, in particular, a globally coupled map are surveyed. First, dominance of Milnor attractors in partially ordered phase is demonstrated. Second, chaotic itinerancy in high-dimensional dynamical systems is briefly reviewed, with discussion on a possible connection with a Milnor attractor network. Third, infinite-dime...
