Simulation of topological superconductors and their competing orders using photon-mediated interactions
Anjun Chu, Joyce Kwan, Eric Yilun Song +3
Realizing and controlling the unconventional pairing featured by topological superconductors remains a central challenge. We introduce a cavity QED quantum simulator that engineers…
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…
A symmetry-protected topological optical lattice clock
Tianrui Xu, Anjun Chu, Kyungtae Kim +4
We theoretically propose a tunable implementation of symmetry-protected topological phases in a synthetic superlattice, taking advantage of the long coherence time and exquisite sp…
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,…
Measurement-induced phase transitions in monitored infinite-range interacting systems
Anna Delmonte, Zejian Li, Gianluca Passarelli +4
A key challenge in observing measurement-induced phase transitions is the mitigation of the post-selection barrier, which causes the reproducibility of specific sequences of measur…
