Quantum chaos

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1993
In this paper we present an overview of important recent results in the study of a very controversial topic, the so-called quantum chaos. The theoretical and numerical results are compared with real laboratory experiments with special emphasis on the problem of ionization of hydrogen atoms in external microwave fields.

Quantum bouncer with chaos

Physical Review Letters, 1993
We report for the first time quantum calculations for the so-called bouncer model, the classical analog of which is well known to manifest a chaotic behavior. Three versions of our model are fully tractable quantum mechanically and are potentially a rich source of data for establishing properties of a quantum system of which the classical mechanics can

Quantum signatures of chaos or quantum chaos?

Physics of Atomic Nuclei, 2016
A critical analysis of the present-day concept of chaos in quantum systems as nothing but a “quantum signature” of chaos in classical mechanics is given. In contrast to the existing semi-intuitive guesses, a definition of classical and quantum chaos is proposed on the basis of the Liouville–Arnold theorem: a quantum chaotic system featuring N degrees ...

Quantum Chaos and Randomness

Journal of the Physical Society of Japan, 2004
Summary: In contrast to the classical Hamiltonian mechanics whose chaotic behaviors are now well established, quantum mechanics is still obscure about the origin of its random behavior. It is shown in this paper that in case of the stadium billiard, the fact that the nodal lines are smooth but are randomly oscillating, as first described by Heller, and

Quantum chaology, not quantum chaos

Physica Scripta, 1989
Summary: There is no quantum chaos, in the sense of exponential sensitivity to initial conditions, but there are several novel quantum phenomena which reflect the presence of classical chaos. The study of these phenomena is quantum chaology.

Quantum chaos in gas

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1996
A new approach to the description of gas kinetics is proposed. The approach is based on a fundamental presumption which states that binary collisions of gas atoms, moving in a chaotic way, can serve as ‘‘interior measurements.’’ These ‘‘measurements’’ result in collapses of atomic wave functions.

Finite Quantum Chaos

The American Mathematical Monthly, 2002
Quantum chaos is in part the study of the statistics of energy levels of a quantum system; i.e., the eigenvalues of the Schrodinger operator. Thus physicists began to investigate the spectra of random large matrices. Similarly number theorists and geometers have investigated the statistics of spectra of Laplacians on Riemannian manifolds which is ...
