SUMMARY

The discussion centers on solving the Poschl-Teller potential problem in quantum mechanics. Participants emphasize the necessity of solving the differential equation associated with the potential, leading to a wavefunction expressed as a combination of exponential terms. Specifically, the wavefunction is derived as Φ = Exp[-ikx](tanh x + ik) + Exp[i k x](tanh x - ik). This formulation is crucial for understanding the behavior of quantum states in the context of the Poschl-Teller potential.

The Attempt at a Solution



Because there is no wavefunction specified, is it sufficient to show A+A- = (ε+1) and hence perform the expansion [(-d/dx)+tanh(x)][(d/dx)+tanh(x)]?

whoops, can mods move to advance physics forum
 
You should solve the differential equation, you'll see that \Phi goes as Exp[-ikx](tanh x + ik) + Exp[i k x] (tanh x - ik )
