Quantum Dynamical Systems with Quasi–Discrete Spectrum
نویسنده
چکیده
We study totally ergodic quantum dynamical systems with quasi–discrete spectrum. We investigate the classification problem for such systems in terms of algebraic invariants. The results are noncommutative analogs of (a part of) the theory of Abramov. Supported in part by the National Science Foundation under grant DMS–9801612

LI-YORKE CHAOTIC GENERALIZED SHIFT DYNAMICAL SYSTEMS
In this text we prove that in generalized shift dynamical system $(X^Gamma,sigma_varphi)$ for finite discrete $X$ with at least two elements, infinite countable set $Gamma$ and arbitrary map $varphi:GammatoGamma$, the following statements are equivalent: - the dynamical system $(X^Gamma,sigma_varphi)$ is Li-Yorke chaotic; - the dynamical system $(X^Gamma,sigma_varphi)$ has an scr...
متن کاملSpace Tilings and Substitutions
We generalize the study of symbolic dynamical systems of nite type and ZZ 2 action, and the associated use of symbolic substitution dynamical systems, to dynamical systems with IR 2 action. The new systems are associated with tilings of the plane. We generalize the classical technique of the matrix of a substitution to include the geometrical information needed to study tilings, and we utilize ...
متن کاملAn algorithmic view of pseudochaos
The controversial concept of quantum chaos – the dynamical chaos in bounded mesoscopic quantum systems – is presented as the most important and universal instance of a new generic dynamical phenomenon: pseudochaos. The latter characterizes the irregular behaviour of dynamical systems with discrete energy and/or frequency spectrum, which include classical systems with discrete phase space. The q...
متن کاملQuantum Hamiltonians with Quasi-ballistic Dynamics and Point Spectrum
Consider the family of Schrödinger operators (and also its Dirac version) on l(Z) or l(N) H W ω,S = ∆+ λF (S n ω) +W, ω ∈ Ω, where S is a transformation on (compact metric) Ω, F a real Lipschitz function and W a (sufficiently fast) power-decaying perturbation. Under certain conditions it is shown that H ω,S presents quasi-ballistic dynamics for ω in a dense Gδ set. Applications include potentia...
متن کاملExactly and quasi-exactly solvable 'discrete' quantum mechanics.
A brief introduction to discrete quantum mechanics is given together with the main results on various exactly solvable systems. Namely, the intertwining relations, shape invariance, Heisenberg operator solutions, annihilation/creation operators and dynamical symmetry algebras, including the q-oscillator algebra and the Askey-Wilson algebra. A simple recipe to construct exactly and quasi-exactly...
