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…
Giant-Atom Effects on Population and Entanglement Dynamics of Rydberg Atoms
Yao-Tong Chen, Lei Du, Yan Zhang +4
Giant atoms are attracting interest as an emerging paradigm in the quantum optics of engineered waveguides. Here we propose to realize a synthetic giant atom working in the optical…
Quantum transport in nonlinear Rudner-Levitov models
Lei Du, Jin-Hui Wu, M. Artoni +1
Quantum transport in a class of nonlinear extensions of the Rudner-Levitov model is numerically studied in this paper. We show that the quantization of the mean displacement, which…
Spatial Kramers-Kronig relation and controlled unidirectional reflection in cold atoms
Yan Zhang, Jin-Hui Wu, M. Artoni +1
We propose a model for realizing frequency-dependent spatial variations of the probe susceptibility in a cold atomic sample. It is found that the usual Kramers-Kronig (KK) relation…
Cross-Phase Modulation and Population Redistribution in a Periodic Tripod Medium
K. Slowik, A. Raczynski, J. Zaremba +3
The cross-Kerr effect is studied for two pulses propagating in an atomic medium in a tripod configuration, dressed by a strong standing wave coupling beam. Nonlinear phase shifts f…
Slow group velocity and Cherenkov radiation
I. Carusotto, M. Artoni, G. C. La Rocca +1
We theoretically study the effect of ultraslow group velocities on the emission of Vavilov-Cherenkov radiation in a coherently driven medium. We show that in this case the aperture…
