含复非线性项的薛定谔方程的Cole-Hopf类变换

Cole-Hopf Like Transformation for Schrödinger Equations Containing Complex Nonlinearities

G. Kaniadakis, A. M. Scarfone

摘要:

我们考虑的系统,保存的粒子数和描述的薛定谔方程包含复杂的非线性。在典型系统的情况下,我们研究他们的主要对称性和守恒律。我们引入了一个Cole-Hopf变换的正则和非正则系统,它改变了另一个包含纯实非线性的发展方程,并减少了线性理论的标准形式的连续性方程。这种方法使我们能够治疗,在一个统一的计划,各种各样的规范和非规范的非线性系统,其中一些已经在文献中。pacs{PACS编号:02.30.Jr,03.50.- z,03.65。w,05.45。a,11.30.Na,11.40.Dw

英文摘要:

We consider systems, which conserve the particle number and are described by Schrödinger equations containing complex nonlinearities. In the case of canonical systems, we study their main symmetries and conservation laws. We introduce a Cole-Hopf like transformation both for canonical and noncanonical systems, which changes the evolution equation into another one containing purely real nonlinearities, and reduces the continuity equation to the standard form of the linear theory. This approach allows us to treat, in a unifying scheme, a wide variety of canonical and noncanonical nonlinear systems, some of them already known in the literature. pacs{PACS number(s): 02.30.Jr, 03.50.-z, 03.65.-w, 05.45.-a, 11.30.Na, 11.40.Dw
