Optical cooling and trapping of tripod-type atoms with rectified radiation forces
Laser cooling and trapping Rectified radiation forces
font style='font-size:12px;'>
2010/10/27
A new scheme of three-dimensional (3D) all-optical (nonmagnetic) cooling and trapping of reso-
nant atoms, based on using of so-called rectified radiation forces in non-monochromatic light fields is ...
Collapse and stable self-trapping for Bose-Einstein condensates with 1/r^b type attractive interatomic interaction potential
Bose-Einstein condensates particles interatomic interaction potential
font style='font-size:12px;'>
2010/4/2
We consider dynamics of Bose-Einstein condensates with long-range attractive interaction proportional to $1/r^b$ and arbitrary angular dependence. It is shown exactly that collapse of Bose-Einstein co...

Collisionless mirror mode trapping
font style='font-size:12px;'>
2009/11/13
We investigate trapping of mirror modes in a magnetic slab. This model is a simplification of a real situation in front of the magnetopause where mirror waves may become trapped in a region close to t...
RF trapping and acceleration in CSNS/RCS
chopping beam loss bunching factor
font style='font-size:12px;'>
2009/8/14
In this paper, two injection scenarios with different chopping rate are discussed. The waveforms of the RF voltage are studied and optimized, respectively. Some suggestions are made, concerning choppi...

In this paper, we establish optimal conditions for maximal energy transfer efficiency using solutions for multilevel systems and interpret these analytical solutions with more intuitive kinetic networ...
Energy Trapping near the Equator in a Numerical Ocean Model
Energy Trapping Equator Numerical Ocean Model
font style='font-size:12px;'>
2009/2/16
The trapped equatorial standing modes described theoretically by Gent (1979) are reproduced in a single vertical-mode numerical ocean model. integrations are carried out in domains whose longitudinal ...
Long-Wave Trapping by Oceanic Ridges
Long-Wave Trapping Oceanic Ridges
font style='font-size:12px;'>
2009/2/10
Long waves are affected by bottom topography and under certain conditions may be trapped along topographical contours which then act as wave guides transmitting wave energy for great distances with li...
Trapping of Waves by a Constant Slope internal Interface in a Two-Layer Ocean
Constant Slope perturbation equation Two-Layer Ocean
font style='font-size:12px;'>
2009/2/7
It is well known that “edge” and “continental shelf” waves can be trapped by a constant slope nearshore bottom; in a two-layer ocean of great constant depth, a constant slope internal interface, as we...
Ultralong trapping of light using double spin coherence gratings
Ultralong light double spin coherence gratings
font style='font-size:12px;'>
2010/4/8
Ultralong trapping of light has been observed in an optically dense three-level solid medium interacting with a pair of counterpropagating coupling fields. Unlike the light trapping based on standing-...
Trapping of a Coastal Density Front by the Bottom Boundary Layer
Coastal Density Front Bottom Boundary Layer Trapping
font style='font-size:12px;'>
2008/12/16
The dynamics of a surface-to-bottom density front on a uniformly sloping continental shelf and the role of density advection in the bottom boundary layer are examined using a three-dimensional, primit...
Coastal Trapping and Funneling Effects on Storm Surges in the Meghna Estuary in Relation to Cyclones Hitting Noakhali–Cox’s Bazar Coast of Bangladesh
Coastal Trapping Bangladesh Meghna Estuary Funneling Effects
font style='font-size:12px;'>
2008/11/5
Studies are described that use a fine-resolution numerical model and incorporate the islands and detailed bottom topography of the Meghna estuary. They show that depending on the characteristics of th...
CH~4氢抽提反应的非绝热trapping型的动力学研究
