U. Leonhardt et al., State reconstruction of wave packets moving in time-dependent potentials and the existence of Wronskian pairs, J PHYS A, 32(2), 1999, pp. 411-418
We determine a class of time-dependent potentials that support the state re
construction of one-dimensional wave packets. For this we extend the projec
tion method (Leonhardt U and Raymer M G 1996 Phys. Rev. Lett. 76 1985) to e
xplicitly time-dependent situations. We require the existence of Wronskian
pairs (regular and irregular wavefunctions) and analyse the consequences on
the possible potentials.
