光晶格中超冷原子的衍射无限位置测量

Diffraction-Unlimited Position Measurement of Ultracold Atoms in an Optical Lattice

Yuto Ashida, Masahito Ueda

摘要:

研究了一种在光晶格中对超冷原子进行高保真度、空间分辨位置测量的方法。我们表明,原子数分布可以在一个空间分辨率超过衍射极限,通过跟踪多体波函数崩溃到Fock状态的渐进演化非破坏性地确定。我们预言,与玻色子相比,泡利不相容原理加速了费米子波函数的坍缩速率。讨论了我们的超越衍射极限原理在其他成像系统中的可能应用。

英文摘要:

We consider a method of high-fidelity, spatially resolved position measurement of ultracold atoms in an optical lattice. We show that the atom-number distribution can be nondestructively determined at a spatial resolution beyond the diffraction limit by tracking the progressive evolution of the many-body wavefunction collapse into a Fock state. We predict that the Pauli exclusion principle accelerates the rate of wavefunction collapse of fermions in comparison with bosons. A possible application of our principle of surpassing the diffraction limit to other imaging systems is discussed.
