In quantum mechanics the operation of spatial inversion is described by equation \\\({\\\bf{P}} \\\Psi (\\\vec{r}) = {m{P}} \\\Psi(- \\\vec{r})\\\) ), where the unitary parity operator P acting on a ► wave function Ψ has only two eigenvalues P=+1 or P=−1 wh...
The parity (or inversion) operator, which changes r to - r , has the alternative interpretation that the coordinate values remain unchanged but the coordinate axes are inverted; that is, the positive x axis of the new frame points along the old negative x axis, and similarly for y and z...

Parity operator and quantization of δ-functions 来自 国家科技图书文献中心 喜欢 0 阅读量: 65 作者: A Grossmann 摘要: In the Weyl quantization scheme, the δ-function at the origin of phase space corresponds to the parity operator. The quantization of a function f (υ) on phase space is...
in quantum mechanics9. A Hamiltonian is called PT symmetric if it commutes with the PT operator, which requires that the real (imaginary) part of the complex potential be an even (odd) function of the coordinates. It was found later that this concept also applies to optical systems due to...

Abstract One of the fundamental axioms of quantum mechanics is associated with the Hermiticity of physical observables1. In the case of the Hamiltonian operator, this requirement not only implies real eigenenergies but also guarantees probability conservation. Interestingly, a wide class of non-Hermitia...

PT symmetry originates from quantum mechanics, where if the Schrodinger operator satisfies the PT symmetry, then its spectrum can be all real. This concept was later introduced into optics, Bose-Einstein condensates, metamaterials, electric circuits, acoustics, mechanical systems and many other fields...
