Summary: This study demonstrates the three-photon Autler-Townes (AT) spectroscopy in a cold cesium Rydberg four-level atom and investigates the positions of AT peaks and AT splittings, as well as their dependence on the characteristics of the coupling lasers. The research finds that AT splitting γ(AB) mainly comes from the first photon coupling, while γ(BC) mainly comes from the second photon coupling. The simulated results show good agreement with the theoretical simulations considering spectral line broadening.

Summary: The effects of laser polarization, magnetic fields, laser intensities, and the optical density of the thermal Rb-87 medium on Rydberg-state electromagnetically-induced-transparency (EIT) were investigated. The study found that high-contrast Rydberg EIT can be achieved under optimized conditions, and this technique can be used as a quantum sensor to detect electromagnetic fields in the environment.

Summary: The experimental results show that the value of the second-order autocorrelation function of the transmitted light significantly varies at different positions within the pulse and during the transients of the pulse; the falling edge of the transmitted pulse displays much lower values compared to the rest of the pulse.

Summary: In this study, electromagnetically induced transparency (EIT) and Autler-Townes splitting in Rydberg rubidium atoms were investigated using a six-level excitation scheme. Experimental results for various excitation parameters were presented, along with two theoretical models capturing different aspects of the observed atomic spectra. Both the six-level model and the more complex eight-level model showed very good agreement with the experimental data.

Summary: This experiment successfully demonstrated the formation of a one-dimensional electromagnetically induced optical lattice in Rydberg atomic vapors and verified the spatially modulated susceptibility of the lattice. This research not only opens the door for exploring Rydberg-atom physics and related applications based on strong interaction in photonic lattices, but also provides a convenient periodic environment for controlling beam dynamics with Rydberg atoms.

Summary: The phase noise of incident light fields can be converted into amplitude noise through absorption and dispersion effects in media under electromagnetically induced transparency, sensitive to two-photon detuning. This effect can be utilized for a different type of Rydberg spectroscopy. Experimental measurements of the phase noise spectrum (PNS) with Rydberg atoms in a cesium vapor cell have been presented, along with the proposal and demonstration of a modulation-enhanced PNS approach for microwave field measurements.

Summary: We demonstrate the use of an auxiliary microwave field to extend the bandwidth sensitivity of Rydberg-atom-based microwave electrometry. By shifting the atomic energy levels with an appropriate auxiliary microwave field, resonance with the target microwave field can be achieved for Rydberg-Rydberg transitions of interest, increasing the measurement sensitivity by a factor of 10 compared to without the auxiliary field.

Summary: In this study, coherent population transfer of Rydberg atoms in Rb-85 is achieved using a dual-microwave driven four-step excitation scheme, with observations of electromagnetically induced transparency, Autler-Townes splitting, and CPT with different energy level configurations. The effects of power and frequency detuning of microwave fields are explored to demonstrate diverse population dynamics. A theoretical model based on the density-matrix is proposed and numerically solved to understand the entire coherent mechanism. Compared to mono-microwave processes, the dual-microwave approach offers optimal coherent transfer evolution with multiple tunable parameters.

Summary: Coherent control of the collective optical properties of an array of quantum emitters can be achieved by driving a single ancilla atom to a Rydberg state. This allows for spatial control over the optical response and enhances light-matter coupling at the level of single quanta. These results represent progress towards realizing quantum coherent metasurfaces, controlled atom-photon entanglement, and deterministic engineering of quantum states of light.

Summary: This study investigates the telecom-wavelength spectra of a Rydberg state in an atomic vapor using a three-photon excitation scheme. By pumping rubidium-85 atoms to a specific state and driving a transition to the Rydberg state, the probe spectra are analyzed over different power levels of the pump lasers. The results, along with a simulation based on a theoretical model, provide important insights for future experiments connecting fiber optics and radio transmission via Rydberg atoms.

Summary: A mechanism for improving the sensitivity of microwave electric field measurement is presented using dual-MW-dressed electromagnetically induced transparency in a Rb-85 atomic coherent system. By introducing an auxiliary MW field and adjusting its frequency and power, the sensitivity of MW E-field measurement is improved by about two orders of magnitude. This mechanism is applicable for all frequency bands covered by Rydberg energy levels and opens up a novel pathway for high-sensitivity MW E-field measurement with Rydberg atoms.

Summary: A scheme for measuring microwave electric fields using bichromatic electromagnetically induced transparency (EIT) in Rydberg atoms is proposed. The absorption spectrum of the excited state transition driven by a bichromatic control field shows three EIT windows. When a microwave field is applied, the EIT windows split and six transmission peaks appear. The distance between the transmission peaks in the spectrum is sensitive to the microwave field strength, allowing for the measurement of the microwave electric field.

Summary: We compare the sensitivity of co-linear three-photon electromagnetically induced transparency (EIT) to radio frequency electric fields in Cs-133 Rydberg atoms against the conventional two-photon system. By modeling the atomic systems, we find that the three-photon system has narrower linewidths but does not align with the regions of best sensitivity. Additionally, we calculate the expected sensitivity for the two-photon Rydberg sensor and find that it is over an order of magnitude better than the current measured values, accounting for additional noise sources and quantum efficiency of photo-detectors.

Summary: Resonant transmission through a dielectric-loaded slot embedded in a thick conducting diaphragm in a rectangular waveguide was studied using an analytical approximation, revealing ordinary and extremely narrowband resonances associated with different modes in the slot. The theoretical predictions were confirmed through numerical simulation and experimental measurement, while additional sharp resonances were observed in measurements on dielectrics consisting of multiple pieces, providing potential applications in sensors and material property measurement.
