摘要

本文检索了共振非线性薛定谔方程扩展版的守恒定律，用于描述量子流体力学和量子光学中的物理过程。乘法运算法找回了三个基本守恒定律。考虑到行波还原，方程的解析解得以找到。守恒量随后可从模型方程的孤子解中计算得出。

Conservation laws for a perturbed resonant nonlinear Schrödinger equation in quantum fluid dynamics and quantum optics

The current paper retrieves the conservation laws for the extended version of the resonant nonlinear Schrödinger's equation for description of physical processes in quantum fluid dynamics and quantum optics. The method of multipliers recovers three fundamental conservation laws. Analytical solutions of equation are found taking into account traveling wave reduction. The conserved quantities are subsequently computed from the soliton solution of the model equation that is derived in this work too.
