Subradiance dynamics in a singly-excited chiral-coupled atomic chain
H. H. Jen, M. -S. Chang, G. -D. Lin +1
We theoretically investigate the subradiance dynamics in a nonreciprocal chiral-coupled atomic chain, in which infinite-range dipole-dipole interaction emerges in the dissipation.…

Cooperative light scattering from helical-phase-imprinted atomic rings
H. H. Jen, M. -S. Chang, Y. -C. Chen
We theoretically investigate the light scattering of the super- and subradiant states which can be prepared by the excitation of a single photon which carries an orbital angular mo…

Entanglement and Tunable Spin-Spin Couplings Between Trapped Ions Using Multiple Transverse Modes
K. Kim, M. -S. Chang, R. Islam +3
We demonstrate tunable spin-spin couplings between trapped atomic ions, mediated by laser forces on multiple transverse collective modes of motion. A -type Ising interacti…
