摘要:

研究了相互作用对玻色两粒子量子行走及其空间关联的影响。相互作用和Hanbury-Brown Twiss干扰的综合效应导致了独特的空间相关性,其依赖于相互作用的强度,但不依赖于其符号。结果解释光的两个粒子的光谱和物理的吸引和排斥绑定对。我们在实验上测量了非线性光子晶格中这些效应的弱相互作用极限。最后,我们讨论了利用光晶格中的单原子观察强相互作用极限的实验方法。

英文摘要:

We study the effect of interactions on the bosonic two-particle quantum walk and its corresponding spatial correlations. The combined effect of interactions and Hanbury-Brown Twiss interference results in unique spatial correlations which depend on the strength of the interaction, but not on its sign. The results are explained in light of the two-particle spectrum and the physics of attractively and repulsively bound pairs. We experimentally measure the weak interaction limit of these effects in nonlinear photonic lattices. Finally, we discuss an experimental approach to observe the strong interaction limit using single atoms in optical lattices.
