BellTest and CHSH experiments with more than two settings

Autor: R M Basoalto, I C Percival

Publikováno v: Journal of Physics A: Mathematical and General. 36:7411-7423

Strong nonlocality allows signals faster than light. Weak nonlocality is a statistical property of classical events for which there is no realistic local theory. This requires the violation of at least one general Bell inequality. The theory of ideal

Mixed classical-quantal representation for open quantum systems

Autor: I. C. Percival, Gernot Alber, T Steimle

Publikováno v: Journal of Physics A: Mathematical and General. 28:L491-L496

For all but the simplest open quantum systems, quantum trajectory Monte Carlo methods, including quantum jump and quantum state diffusion (QSD) methods, have besides their intuitive insight into the measurement process a numerical advantage over dire

Localization of wide-open quantum systems

Autor: I C Percival

Publikováno v: Journal of Physics A: Mathematical and General. 27:1003-1020

In a wide-open quantum system, the effect of the Hamiltonian is negligible by comparison with the effect of the environment. For open systems, this is the opposite limit to closed or isolated systems. The quantum state diffusion model provides equati

Local realism, detection efficiencies, and probability polytopes

Autor: Yann Disser, I. C. Percival, J. Wilms, Gernot Alber

Publikováno v: Physical Review A. 78

We present a detailed investigation of minimum detection efficiencies, below which local realism cannot be violated by any quantum system of any dimension in bipartite Bell experiments. Lower bounds on these minimum detection efficiencies are determi

Decoherence of quantum wavepackets due to interaction with conformal spacetime fluctuations

Autor: W. L. Power, I. C. Percival

One of the biggest problems faced by those attempting to combine quantum theory and general relativity is the experimental inaccessibility of the unification scale. In this paper we show how incoherent conformal waves in the gravitational field, whic

Classical theory of the static Stark effect for weak fields

Autor: A de Kertanguy, I C Percival, D Richards

Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 14:641-656

The classical theory is presented for an atom with one excited electron subject to Coulomb attraction and the long-range potential of a polarisable core. The electric field must not be so strong as to mix states of different principal quantum number.

Classical theory of transitions between degenerate states of excited hydrogen atoms in plasmas

Autor: D Richards, I C Percival

Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 12:2051-2065

The authors present a general classical theory of transitions between degenerate states of hydrogen-like atoms and ions, with particular application to multiple overlapping collisions with the charged particles of an isotropic plasma. They classify i

Variational principles for the invariant toroids of classical dynamics

Autor: I C Percival

Publikováno v: Journal of Physics A: Mathematical, Nuclear and General. 7:794-802

Kolmogorov (1957), Arnol'd (1973) and Moser (1962) proved that invariant toroids of N dimensions occupy a finite volume of the 2N-dimensional phase space of nearly integrable bounded systems of N degrees of freedom. Variational principles are stated

Vibrational excitation and the Feynman correspondence identity

Autor: A P Clark, I C Percival

Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 8:1939-1952

A method, based on evolution operators and aided by diagrams is used to obtain a semiclassical expression for the transition probabilities in the time-dependent formulation of scattering theory. As a consequence of the Feynman correspondence identity
