The interaction between a hydrogen atom and circularly polarized light leads to a complex nonlinear oscillator equation, whose solution describes the electron's perturbed orbit as a sum of epicyclical motions.
תקציר
The paper investigates the dynamics of a hydrogen electron under the influence of a circularly polarized light field. It uses Clifford algebra Cl2,0 to derive a complex nonlinear differential equation that describes the perturbation of the electron's initial circular orbit.
Key highlights:
- The unperturbed electron orbit is described by a rotating vector in the complex plane, rotating at the Kepler frequency ω0.
- The perturbation equation is similar to but different from the standard Lorentz oscillator equation, with differences in the acceleration, damping, and spring-like terms.
- The perturbation equation is nonlinear due to the presence of a complex conjugate term, which has no analog in the Lorentz model.
- The solution for the perturbed orbit is expressed as a sum of five exponential Fourier terms, corresponding to the eccentric, deferent, and three epicycles in Copernican astronomy.
- At resonant light frequencies (ω/ω0 = 0, 1, 2), the electron's orbit becomes divergent but approximates a Keplerian ellipse.
- At other light frequencies, the orbits are non-divergent with periods that are integer multiples of π/ω0, depending on the frequency ratio ω/ω0.
- As the frequency ratio ω/ω0 approaches ±∞, the orbit approaches the unperturbed circular orbit.
