具有随机势的非线性Schroedinger方程的双峰态

Double humped states in the nonlinear Schroedinger equation with a random potential

Hagar Veksler, Yevgeny Krivolapov, Shmuel Fishman

摘要:

研究了具有随机势的非线性薛定谔方程(NLSE)中双峰态在波包扩展中的作用,揭示了其扩展机制。与双阱势的NLSE进行了比较。非线性效应对双峰态的影响有两个独立的方面:与其它态的耦合和破坏。这些影响之间的相互作用进行了讨论。

英文摘要:

The role of double humped states in spreading of wave packets for the nonlinear Schroedinger equation (NLSE) with a random potential is explored and the spreading mechanism is unraveled. Comparison with an NLSE with a double-well potential is made. There are two independent affects of the nonlinearity on the double humped states for the NLSE: coupling to other states and destruction. The interplay between these effects is discussed.
