The dynamics of nonstationary solutions in one-dimensional two-component Bose-Einstein condensates
《Chinese Physics B》2011年第2期60-69,共10页吕彬彬 郝雪 田强 
supported by the National Natural Science Foundation of China (Grant No. 1057411);the Foundation for Researching Group by Beijing Normal University;the Foundation for Outstanding Doctoral Dissertation by Beijing Normal University
This paper investigates the dynamical properties of nonstationary solutions in one-dimensional two-component Bose-Einstein condensates. It gives three kinds of stationary solutions to this model and develops a general...

Discrete breathers in a model with Morse potentials
《Chinese Physics B》2010年第2期381-387,共7页吕彬彬 邓艳平 田强 
supported by the National Natural Science Foundation of China (Grant No. 1057411);the Foundation for Researching Group by Beijing Normal University
Under harmonic approximation, this paper discusses the linear dispersion relation of the one-dimensional chain. The existence and evolution of discrete breathers in a general one-dimensional chain are analysed for two...
