一维Dirac方程中的无反射PT对称势

Reflectionless PT-symmetric potentials in the one-dimensional Dirac equation

Francesco Cannata, Alberto Ventura

摘要:

我们研究了具有局部PT对称势的一维Dirac方程,其离散本征函数和连续渐近本征函数也是PT算子的本征函数:在这些条件下,束缚态谱是实的,势是无反射的,并且在散射过程中保持么正性。没有反射使得考虑不渐近消失的PT对称势也是有意义的。

英文摘要:

We study the one-dimensional Dirac equation with local PT-symmetric potentials whose discrete eigenfunctions and continuum asymptotic eigenfunctions are eigenfunctions of the PT operator, too: on these conditions the bound-state spectra are real and the potentials are reflectionless and conserve unitarity in the scattering process. Absence of reflection makes it meaningful to consider also PT-symmetric potentials that do not vanish asymptotically.
