Coherence of matter-wave, high-frequency potential atomic guide, transport and convergence of cold atoms, and fifth forces due to scalar field and dark energy.
 His recent work focuses on detecting a scalar fifth force under laboratory conditions, and obtaining a scalar fifth force via a symmetry-breaking coupling function.
PhD in Physics from Zhongshan (Sun Yat-Sen) University in 2002.
Honors & Achievements
 He has been exploring how experiments using cold atoms may detect a scalar fifth force (https://arxiv.org/abs/1702.03050) and how a novel conceptualization of cosmic evolution—relying on a symmetry-breaking coupling function—may prove to be consistent with the most updated Planck 2018 results.
 He has proposed an approach—applying the symmetry-breaking coupling function—that may evade the two NO-GO theorems (Chameleon no-go theorem and Weinberg’s no-go theorem).
