Universal irreversibility of normal quantum diffusion.

چکیده
Time-reversibility measured by the deviation of perturbed time-reversed motion from the unperturbed motion is examined for normal quantum diffusion exhibited by four classes of quantum maps with contrasting physical nature. Irrespective of the system, there exists a universal minimal quantum threshold above which the system completely loses memory of the past. The time-reversed dynamics as well as the time-reversal characteristics are asymptotically universal curves independent of the details of the systems.

متن کاملThe Quantum Statistical Mechanical Theory of Transport Processes
A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
متن کاملQuantum Irreversibility in Arbitrary Dimension
Some recent ideas are generalized from four dimensions to the general dimension n. Two terms of the trace anomaly in external gravity, the Euler density Gn and 2 R, are relevant to the problem of quantum irreversibility. By adding the divergence of a gauge-invariant current, Gn can be extended to a new notion of Euler density G̃n, linear in the conformal factor. We call it pondered Euler density...
متن کاملQuantum Chaos, Irreversibility, dissipation and dephasing
The main idea of ”Quantum Chaos” studies is that Quantum Mechanics introduces two energy scales into the study of chaotic systems: One is obviously the mean level spacing ∆ ∝ h̄, where d is the dimensionality; The other is ∆b ∝ h̄, which is known as the non-universal energy scale, or as the bandwidth, or as the Thouless energy. Associated with these two energy scales are two special quantum-mecha...
متن کاملSum Rules for Trace Anomalies and Irreversibility of the Renormalization-group Flow
The purpose of my talk is to review exact results for the trace anomalies c and a in the critical limits of supersymmetric theories, which provide non-perturbative evidence that the renormalization-group (RG) flow is irreversible, and then derive universal sum rules for c, a and a in even dimensions, formulate a theory of the irreversibility of the RG flow, recapitulate the arguments and the ev...
