Collective three-body interactions enable a robust quantum speedup
Haoqing Zhang, Anjun Chu, Chengyi Luo +4
We show that collective three-body interactions (3BIs), implementable with atoms loaded inside an optical cavity, offer a significant advantage for preparing complex multiparti…

Solitons in arbitrary dimensions stabilized by photon-mediated interactions
Haoqing Zhang, Anjun Chu, Chengyi Luo +2
We propose a scheme to generate solitons in arbitrary dimensions, in a matter-wave interferometer, without the need of quantum degeneracy. In our setting, solitons emerge by balanc…

Realization of three and four-body interactions between momentum states in a cavity through optical dressing
Chengyi Luo, Haoqing Zhang, Chitose Maruko +4
Paradigmatic spin Hamiltonians in condensed matter and quantum sensing typically utilize pair-wise or 2-body interactions between constituents in the material or ensemble. However,…
