STRONG ATOM–PHOTON COUPLING, BOUNDARIES, AND RADIATION–INFORMATION

Vidamor Cabannas

This article develops an expanded critical–propositional analysis of Takao Aoki and collaborators’ 2006 experimental study, “Observation of Strong Coupling between One Atom and a Monolithic Microresonator,” in systematic dialogue with the Theory of Objectivity (TO), developed by Vidamor Cabannas and Denivaldo Silva. Aoki et al. experimentally demonstrated strong coupling between an individual cesium atom and the quantized optical field of a high-quality monolithic toroidal microresonator. Their measurements yielded a maximum atom–field coupling rate g m 0 /2π = (50 ± 12) MHz, larger than both the cavity-field decay rate κ/2π = (17.9 ± 2.8) MHz and the atomic dissipation rate γ/2π = 2.6 MHz. The experiment therefore provides a particularly clear case in which an elemen- tary matter–radiation relation produces measurable, coherent, boundary-dependent consequences at the scale of a single atom and very few photons. The analysis distinguishes three epistemological levels: experimentally estab- lished CQED results, structural compatibility with TO, and specifically TO-dependent ontological claims requiring independent operational tests. Particular attention is given to the Seven Absolute Truths of TO, especially VA4, concerning boundaries or interfaces, and VA7, concerning the transcendent element understood within TO as knowledge or information produced in atomic relations and equivalent to atomic radiation. VA5, concerning triangular observation, and VA6, concerning composition from preceding elements, also exhibit significant structural dialogue with the experiment, whereas VA1 and VA3 remain largely beyond its empirical scope. The article further examines TO’s phenomenic elements, Inductive Effects, cos- mogonic theorem, cosmological Eras, Law of Logical Minimum, and recent program of operational bridges. Aoki et al. are interpreted as providing indirect empirical corroboration for limited phenomenological propositions of TO—particularly the physi- cal efficacy of individual atomic relations, the constitutive role of interfaces, and the capacity of radiation to encode information concerning those relations—but not as demonstrating TO’s modal axioms or cosmological architecture. A concrete CQED-inspired testing program is proposed in which TO would have to specify measurable residual information, boundary-dependent corrections, or other departures from standard cavity quantum electrodynamics. The article concludes that Aoki et al. merit a score of 8.2/10 for their degree of dialogue with TO: strong at the atomic, radiative, informational, and boundary levels, but indirect at the level of modal ontology and highly indirect at the cosmogonic level. Keywords: Theory of Objectivity; cavity quantum electrodynamics; CQED; strong coupling; single atom; microresonator; quantum optics; boundary; information; atomic radiation; transcendent element; Inductive Effects; modal necessity; empirical corrobo- ration; operational bridge.

Cavity QED with chip-based toroidal microresonators

Barak Dayan, T. Aoki, E. Wilcut +8 more

We report the demonstration of strong coupling between single Cesium atoms and a high-Q chip-based microresonator. Our toroidal microresonators are compact, Si chip-based whispering gallery mode resonators that confine light to small volumes with extremely low losses, and are manufactured in large numbers by standard lithographic techniques. Combined with the capability to couple efficiently light to and from these microresonators by a tapered optical fiber, toroidal microresonators offer a promising avenue towards scalable quantum networks. Experimentally, laser cooled Cs atoms are dropped onto a toroidal microresonator while a probe beam is critically coupled to the cavity mode. When an atom interacts with the cavity, it modifies the resonance spectrum of the cavity, leading to rejection of some of the probe light from the cavity, and thus to an increase in the output power. By observing such transit events while systematically detuning the cavity from the atomic resonance, we determine the maximal accessible single-photon Rabi frequency of Ω0/2π ≈ (100 ± 24) MHz. This value puts our system in the regime of strong coupling, being significantly larger than the dissipation rates in our system.
