论文摘要
讨论了在chi驱动的rydberg原子中量子力学和经典演变之间的相互作用。结果表明，该系统允许两种持续的共振激发机制，即连续的两级过渡（梯子攀爬）和持续的经典非线性相位锁定（自动抗量）。详细研究了驱动器和开普勒频率之间的持续$ 1：1 $和$ 2：1 $的共振，并以二小无参数为特征$ p_ {1,2} $，分别代表了问题中的驾驶强度和非线性。量子力学旋转波和经典的单共振近似用于描述此两参数空间中有效的经典或量子力学激发的制度。
The interplay between quantum-mechanical and classical evolutions in a chirped driven Rydberg atom is discussed. It is shown that the system allows two continuing resonant excitation mechanisms, i.e., a successive two-level transitions (ladder climbing) and a continuing classical-like nonlinear phase locking (autoresonance). The persistent $1:1$ and $2:1$ resonances between the driving and the Keplerian frequencies are studied in detail and characterized in terms of two dimensionless parameters $P_{1,2}$ representing the driving strength and the nonlinearity in the problem, respectively. The quantum-mechanical rotating wave and the classical single resonance approximations are used to describe the regimes of efficient classical or quantum-mechanical excitation in this two-parameter space.
