量子雪橇

Quantum toboggans

Miloslav Znojil

摘要:

在所有定义在复坐标轮廓C(s)上的PT-对称势中,“量子滑降”这个名字是为那些C(s)围绕着一个奇点并且至少存在于两个不同的黎曼面上的势保留的。一个丰富的菜单,前瞻性的现象学模型,然后可以通过简单的变量的变化。我们彻底注意到谐振子的例子与分数屏蔽,并强调的存在性和不变性的作用,其准精确状态的不同tobogganic C(s)。

英文摘要:

Among all the PT-symmetric potentials defined on complex coordinate contours C(s), the name "quantum toboggan" is reserved for those whose C(s) winds around a singularity and lives on at least two different Riemann sheets. An enriched menu of prospective phenomenological models is then obtainable via the mere changes of variables. We pay thorough attention to the harmonic oscillator example with a fractional screening and emphasize the role of the existence and invariance of its quasi-exact states for different tobogganic C(s).
