Wigner函数在辛映射下的变换

How Wigner Functions Transform Under Symplectic Maps

Alex J. Dragt, Salman Habib

摘要:

结果表明,虽然维格纳和刘维函数变换在线性辛映射下以相同的方式,在一般情况下,他们不变换相同的非线性辛映射。相反,有“量子修正”,其hbar趋于零极限可能非常复杂。在此极限的维格纳函数的行为的例子,以检查在何种程度上相应的刘维尔密度恢复。

英文摘要:

It is shown that, while Wigner and Liouville functions transform in an identical way under linear symplectic maps, in general they do not transform identically for nonlinear symplectic maps. Instead there are ``quantum corrections'' whose hbar tending to zero limit may be very complicated. Examples of the behavior of Wigner functions in this limit are given in order to examine to what extent the corresponding Liouville densities are recovered.
