Chaotic oscillation in an attractive Bose-Einstein condensate under an impulsive force
(2002-01-01)
For an attractive trapped Bose-Einstein condensate an imaginary three-body recombination loss term and an imaginary linear source term are usually included in the Gross-Pitaevskii (GP) equation for a proper account of ...
The influence of planetary attractions on the solar tachocline
(Elsevier, 2012-05)
We present a physical analysis of the occasionally forwarded hypothesis that solar variability, as shown in the various photospheric and outer solar layer activities, might be due to the Newtonian attraction by the planets. ...

Dynamical properties for a mixed Fermi accelerator model
(2013-10-01)
The behavior of the decay of velocity in a semi-dissipative one-dimensional Fermi accelerator model is considered. Two different kinds of dissipative forces were considered: (i) F-v and; (ii) F-v2. We prove the decay of ...

A simplified Fermi Accelerator Model under quadratic frictional force
(Sociedade Brasileira de Física, 2008-03-01)
Some dynamical properties for a simplified version of a one-dimensional Fermi Accelerator Model under the action of a small dissipation is studied. The dissipation is introduced via a damping force which is assumed to be ...
Hydrophobic surfaces probed by atomic force microscopy

Periodic motions in forced problems of Kepler type
(Birkhauser Verlag Ag, 2011-12)
A Newtonian equation in the plane is considered. There is a central force (attractive or repulsive) and an external force λh(t), periodic in time. The periodic second primitive of h(t) defines a planar curve and the number ...
Chaotic oscillation in an attractive Bose-Einstein condensate under an impulsive force
(2002-04-01)
The chaotic oscillation in an attractive Bose-Einstein condensate (BEC) under an impulsive force was discussed using mean-field Gross-Pitaevskii (GP) equation. It was found that sustained chaotic oscillation resulted in a ...
The New Geography of Jobs
We - re used to thinking of the United States in opposing terms: red versus blue, haves versus have-nots. But today there are three Americas. At one extreme are the brain hubs - cities like San Francisco, Boston, and Durham ...
