Dark pair coherent states of the motion of a trapped ion.

We propose a scheme for generating vibrational pair coherent states of the motion of an ion in a two-dimensional trap. In our scheme, the trapped ion is excited bichromatically by three laser beams along different directions in the X-Y plane of the ion trap. We show that if the initial vibrational state is given by a two-mode Fock state, the final steady state, indicated by the extinction of th...

Considering the concept of ”nonlinear coherent states”, we will study the interference effects by introducing the ”superposition of two classes of nonlinear coherent states” which are π 2 out of phase. The formalism has then been applied to a few physical systems as ”harmonious states”, ”SU(1, 1) coherent states” and ”the center of mass motion of trapped ion”. Finally, the nonclassical properti...

In this paper we present a scheme for constructing the coherent states of Klauder-Perelomov’s type for a particle which is trapped in Pöschl-Teller potentials.

0 A pr 1 99 6 The Dispersion - Velocity of Galactic Dark Matter Particles

The self-consistent spatial distribution of particles of Galactic dark matter is derived including their own gravitational potential, as also of that of the visible matter of the Galaxy. In order to reproduce the observed rotation curve of the Galaxy the value of the dispersion velocity of the dark matter particles, v 2 1/2 DM , should be ∼ 600 km s −1 or larger.
