Efficient biphoton generation by a waveguide-coupled single atom
Mao-Hua Wang, Xiao-Jun Zhang, M. Artoni +2
A single atom undergoing spontaneous four-wave mixing near a chiral waveguide can efficiently channel an emitted Stokes-anti-Stokes photon pair into two tightly confined waveguide…

Enhancing ground-state interaction strength of neutral atoms via Floquet stroboscopic dynamics
Y. Wei, M. Artoni, G. C. La Rocca +2
Neutral atom systems are promising platforms for quantum simulation and computation, owing to their long coherence times. However, their intrinsically weak ground-state interaction…

Single-photon manipulations based on optically-controlled chiral couplings in waveguide structures of Rydberg giant atoms
Yao-Tong Chen, Lei Du, Zhihai Wang +3
Two interacting Rydberg atoms coupled to a waveguide realize a giant-atom platform that exhibits the controllable (phase-dependent) chirality where the direction of nonreciprocal p…
