Pöschl-teller Paradoxes 3.1 Refined Boundary Conditions
In the well known Pöschl-Teller trigonometric potential well, a PT symmetric regularization x → x− i ε of the “impenetrable” end-point barriers is performed. This leads to the four different solvable generalizations of the model. As a byproduct, the scheme clarifies certain apparent paradoxes encountered in the classically forbidden coupling regime.

متن کامل2 00 1 A new dynamical group approach to the Modified Pöschl - Teller potential
The properties of the wave function for the Modified Pöschl-Teller (MPT) potential are outlined. The ladder operators are constructed directly from the wave functions without introducing any auxiliary parameter. It is shown that these operators are associated to the su(2) algebra. Analytical expressions for the functions sinh(αx) and cosh(αx) α d dx are evaluated from ladder operators. The expa...
متن کاملSe p 20 05 FUNCTION SPACES ASSOCIATED WITH SCHRÖDINGER OPERATORS : THE PÖSCHL - TELLER POTENTIAL
Abstract. We address the function space theory associated with the Schrödinger operatorH = −d2/dx2+V . The discussion is featured with potential V (x) = −λ(λ−1) sechx, which is called in quantum physics the Pöschl-Teller potential. Using biorthogonal dyadic system, we introduce Besov spaces and Triebel-Lizorkin spaces (including Sobolev spaces) associated with H . We then use interpolation meth...
متن کاملComment on ‘ Application of nonlinear deformation algebra to a physical system with Pöschl - Teller potential ’
We comment on a recent paper by Chen, Liu, and Ge (J. Phys. A: Math. Gen. 31 (1998) 6473), wherein a nonlinear deformation of su(1,1) involving two deforming functions is realized in the exactly solvable quantum-mechanical problem with Pöschl-Teller potential, and is used to derive the well-known su(1,1) spectrum-generating algebra of this problem. We show that one of the defining relations of ...
متن کاملPt −symetrically Regularized Eckart, Pöschl-teller and Hulthén Potentials
PT (= parity times time-reversal) symmetry of complex Hamiltonians with real spectra is usually interpreted as a weaker mathematical substitute for Hermiticity. Perhaps an equally important role is played by the related strengthened analyticity assumptions. In a constructive illustration we complexify a few potentials solvable only in s−wave. Then we continue their domain from semi-axis to the ...
