薛定谔方程作为哈密顿系统、二阶张量流形和量子力学中非线性的新观点

Schrödinger and related equations as Hamiltonian systems, manifolds of second-order tensors and new ideas of nonlinearity in quantum mechanics

J. J. Sławianowski, V. Kovalchuk

摘要:

考虑的是有限维空间中的薛定谔方程作为一个数学物理方程,可从变分原理导出,并可处理的拉格朗日-汉密尔顿形式主义。它提供了一个有趣的例子“力学”奇异拉格朗日,有效地处理的狄拉克形式主义的框架内。我们还讨论了一些修改的“薛定谔”方程,涉及二阶时间导数,并介绍了一种非直接的,非微扰,几何动机的非线性的基础上使标量积的动力学量。我们有理由期待,这可能是描述开放动力系统和解释某些量子“悖论”的一种新方法。

英文摘要:

Considered is the Schrödinger equation in a finite-dimensional space as an equation of mathematical physics derivable from the variational principle and treatable in terms of the Lagrange-Hamilton formalism. It provides an interesting example of "mechanics" with singular Lagrangians, effectively treatable within the framework of Dirac formalism. We discuss also some modified "Schrödinger" equations involving second-order time derivatives and introduce a kind of non-direct, non-perturbative, geometrically-motivated nonlinearity based on making the scalar product a dynamical quantity. There are some reasons to expect that this might be a new way of describing open dynamical systems and explaining some quantum "paradoxes".
