Abstract: | We have studied the quantum and classical motions of a single Paul
trapped ion interacting with a time-periodic laser field. By using
the test-function method, we construct n exact solutions of quantum dynamics that describe the generalized squeezed coherent states with the expectation orbits being the corresponding
classical ones. The space-time evolutions of the exact probability
densities show some wavepacket trains. It is demonstrated analytically that by adjusting the laser intensity and frequency, we can control the center motions of the wavepacket trains. We
also discuss the other physical properties such as the expectation
value of energy, the widths and heights of the wavepackets, and
the resonance loss of stability. |
