Time-evolution of a Schrödinger electron driven by a localized oscillating potential

POSTER

Abstract

We have obtained a semi-analytical solution of the Schrödinger equation for a massive particle in the presence of a harmonic time-dependent ∼ cos (ω t) single-point ∼ δ(x) potential. We present a detailed analysis for determining the dependence of the wave function on the amplitude and frequency of the oscillatory potential, and the chosen initial conditions for the particle wave function. We have considered separately when either the potential is negative and leads to a bound state or ispositive thus yielding scattering. Our derived results could be interpreted as being related to the dynamics of an electronic Floquet state subjected to a localized laser-induced dressing field.
