旋转超流体流体动力学方程的严格推导
Rigorous derivation of the hydrodynamical equations for rotating superfluids
摘要:
利用一种改进的WKB方法,我们给出了具有转动强迫的非线性Schroedinger方程解的严格半经典分析。这为旋转超流体的流体动力学系统提供了一个严格的证明。特别地,当极限流体动力学系统具有全局光滑解时,全局时间半经典收敛成立,并且我们还讨论了描述旋转超流体的几个物理量的半经典动力学.
英文摘要:
Using a modified WKB approach, we present a rigorous semi-classical analysis for solutions of nonlinear Schroedinger equations with rotational forcing. This yields a rigorous justification for the hydrodynamical system of rotating superfluids. In particular it is shown that global-in-time semi-classical convergence holds whenever the limiting hydrodynamical system has global smooth solutions and we also discuss the semi-classical dynamics of several physical quantities describing rotating superfluids.
