| Abstract | |
We present an analytic method, based on the Bohmian equations for quantum mechanics, for approaching the phase-retrieval problem in the following formulation: by knowing the probability density <mml:mfenced close={''}|{''} open={''}|{''}>psi <mml:mfenced close={''}){''} open={''}({''}>r -></mml:mover>,t</mml:mfenced></mml:mfenced>2 and the energy potential V<mml:mfenced close={''}){''} open={''}({''}>r -></mml:mover>,t</mml:mfenced> of a system, how can one determine the complex state psi <mml:mfenced close={''}){''} open={''}({''}><mml:mover accent={''}true{''}>r<mml:mo stretchy={''}false{''}>-></mml:mover><mml:mo>,t</mml:mfenced>? We illustrate our method with three classic examples involving Gaussian states, suggesting applications to quantum state and Hamiltonian engineering. (AU) | |
