Scattering and intrinsic irreversibility
The search of a physical explanation for the evolution towards equilibrium of quantum systems has a great interest for quantum statistical mechanics. For many years a great number of papers were devoted to this problem. The microscopic explanation of the approach to equilibrium was related to the so called ’intrinsic irreversibility’ of quantum systems. B.Misra, I.Prigogine, M.Courbage [1] [2] ...
متن کاملIntrinsic irreversibility of Markovian chains.
We show that for a large class of stationary Markov processes the total variation distance between the final equilibrium distribution and that at a given time is a strongly monotonic vanishing function. We illustrate this for basic paradigmatic processes and discuss how, for systems susceptible to a canonical description, this can be interpreted as a statistical arrow of time that exists beside...
متن کاملIntrinsic randomness and intrinsic irreversibility in classical dynamical systems.
We continue our previous work on dynamic "intrinsically random" systems for which we can derive dissipative Markov processes through a one-to-one change of representation. For these systems, the unitary group of evolution can be transformed in this way into two distinct Markov processes leading to equilibrium for either t--> + infinity or t--> - infinity. To lift the degeneracy, we first formul...
متن کاملExtrinsic and Intrinsic Irreversibility in Probabilistic Dynamical Laws
Two distinct conceptions for the relation between reversible, time-reversal invariant laws of nature and the irreversible behavior of physical systems are outlined. The standard, extrinsic concept of irreversibility is based on the notion of an open system interacting with its environment. An alternative, intrinsic concept of irreversibility does not explicitly refer to any environment at all. ...
متن کاملIntrinsic Irreversibility and Sz.-Nagy-Foiaş Dilation Theory
An exact theory of irreversibility was proposed by Misra, Prigogine and Courbage (MPC) based on a non-unitary similarity transformation Λ mapping reversible dynamics into irreversible ones. In this work a characterization of the irreversible dynamics induced by the MPC theory, the structure of the reversible evolutions admitting such type of change of representation and a prototype for the tran...
