Time Evolution of Simple Quantum-Mechanical Systems. II. Two-State System in Intense Fields
W. R. Salzman · Physical Review Letters · 1971
The Schr\"odinger equation for a two-state quantum-mechanical system with sinusoidal perturbation is numerically integrated with respect to time. From these results a general formula for the induced transition probability (as a function of time, perturbation frequency, and perturbation strength) is extracted.
