周期势场中原子的混沌“旋转门”
A chaotic 'turnstile' for atoms in periodic potentials
摘要:
利用一种新型的混沌棘轮产生的脉冲驻波的光,我们提出了一种机制,这将允许通过一个方向的脉冲光晶格旅行的原子包几乎不受干扰地通过,而强烈加热原子漂移通过相反的方向。导出了扩散能增长的解析公式,并与数值计算结果吻合良好。
英文摘要:
Using a new type of chaotic ratchet generated by pulsed standing waves of light, we propose a mechanism which would allow packets of atoms travelling through a pulsed optical lattice in one direction to pass almost undisturbed, while strongly heating atoms drifting through in the opposite direction. An analytical formula for the diffusive energy growth is derived and shown to give good agreement with numerical calculations.
