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…
Non-Hermitian optical scattering in cold atoms via four-wave mixing
Xiao Liu, M. Artoni, G. C. La Rocca +1
Nonlinear effects could play a crucial role in addressing optical nonreciprocal behaviors in scattering media. Such behaviors are, however, typically observed within a single trans…
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…
Microscopic Theory of Polariton Lasing via Vibronically Assisted Scattering
Leonardo Mazza, Stéphane Kéna-Cohen, Paolo Michetti +1
Polariton lasing has recently been observed in strongly coupled crystalline anthracene microcavities. A simple model is developed describing the onset of the non-linear threshold b…
Optical non-reciprocity of cold atom Bragg mirrors in motion
S. A. R. Horsley, J. -H. Wu, M. Artoni +1
Reciprocity is fundamental to light transport and is a concept that holds also in rather complex systems. Yet, reciprocity can be switched off even in linear, isotropic and passive…
Revisiting the Bragg reflector to illustrate some modern developments in optics
S. A. R. Horsley, J. -H. Wu, M. Artoni +1
A series of thin layers of alternating refractive index is known to make a good optical mirror over certain bands of frequency. Such a device - often termed the Bragg reflector - i…
Role of anisotropy in the Förster energy transfer from a semiconductor quantum well to an organic crystalline overlayer
S. Kawka, G. C. La Rocca
We consider the non-radiative resonant energy transfer from a two-dimensional Wannier exciton (donor) to a Frenkel exciton of a molecular crystal overlayer (acceptor). We character…
Radiation pressure on a moving body: beyond the Doppler effect
S. A. R. Horsley, M. Artoni, G. C. La Rocca
The dependence of macroscopic radiation pressure on the velocity of the object being pushed is commonly attributed to the Doppler effect. This need not be the case, and here we hig…
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…
Radiation 'damping' in atomic photonic crystals
S. A. R. Horsley, M. Artoni, G. C. La Rocca
The force exerted on a material by an incident beam of light is dependent upon the material's velocity in the laboratory frame of reference. This velocity dependence is known to be…
Exciton-phonon scattering and photo-excitation dynamics in J-aggregate microcavities
P. Michetti, G. C. La Rocca
We have developed a model accounting for the photo-excitation dynamics and the photoluminescence of strongly coupled J-aggregate microcavities. Our model is based on a description…
Nonlinear atom optics and bright gap soliton generation in finite optical lattices
Iacopo Carusotto, Davide Embriaco, Giuseppe C. La Rocca
We theoretically investigate the transmission dynamics of coherent matter wave pulses across finite optical lattices in both the linear and the nonlinear regimes. The shape and the…
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…
