Bright and Dark Solitons in a Periodically Attractive and Expulsive Potential with Nonlinearities Modulated in Space and Time
摘要：
本文研究了具有多种非线性项的非线性薛定谔方程的孤子解。我们解决了一个潜在的吸引力和排斥行为之间的时间振荡的方程，在空间和时间调制的非线性的存在。尽管存在周期性排斥行为的潜在的，结果表明，非线性方程可以支持的明亮和黑暗的类型，这是非常强大的局域激发的多样性。
英文摘要：
This work deals with soliton solutions of the nonlinear Schroedinger equation with a diversity of nonlinearities. We solve the equation in a potential which oscillates in time between attractive and expulsive behavior, in the presence of nonlinearities which are modulated in space and time. Despite the presence of the periodically expulsive behavior of the potential, the results show that the nonlinear equation can support a diversity of localized excitations of the bright and dark type which are remarkably robust.
