In mathematical physics, a Pöschl–Teller potential, named after the physicists Herta Pöschl〔("Edward Teller Biographical Memoir." by Stephen B. Libby and Andrew M. Sessler, 2009 (published in ''Edward Teller Centennial Symposium: modern physics and the scientific legacy of Edward Teller'', World Scientific, 2010. )〕 (credited as G. Pöschl) and Edward Teller, is a special class of potentials for which the one-dimensional Schrödinger equation can be solved in terms of special functions. ==Definition== It is explicitly given by : and the solutions of the time-independent Schrödinger equation : with this potential can be found by virtue of the substitution , which yields : . Thus the solutions are just the Legendre functions with . Moreover, eigenvalues and scattering data can be explicitly computed.〔Siegfried Flügge ''Practical Quantum Mechanics'' (Springer, 1998)〕 In the special case of integer , the potential is reflectionless and such potentials also arise as the N-soliton solutions of the Korteweg-de Vries equation. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Pöschl–Teller potential」の詳細全文を読む スポンサード リンク
