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: 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: 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: The probe absorption characteristic of a four-level ladder-type system under the influence of two strong coherent radiation fields is analyzed using the density operator method. The study reveals that the two-photon electromagnetically induced transparency (EIT) can be converted into double EIT (DEIT) window with a strong central absorption peak by applying a switching field in addition to the control field. In a thermal vapor, the DEIT window can be transformed into three transparency windows depending on the values of the control and switching Rabi frequencies. The article also demonstrates the conceptualization of a very narrow optical band stop filter using a three-photon excitation scheme and investigates the transient optical response of the medium under both Doppler free and Doppler broadened conditions.

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: 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: A laser frequency stabilization technique is proposed for exciting non-ground state atomic transitions in order to reduce the size, weight, power, and cost requirements of quantum sensing devices. This technique overcomes the challenges posed by large optical cavities and high optical power usage for frequency stabilization, requiring only minimal additional electronics. Experimental results show that Rydberg electric field sensors using this technique can collect data while sacrificing only 0.1% of available bandwidth for frequency stabilization up to 900 Hz.

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: 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: This study presents a comparative theoretical investigation of two-photon and three-photon electromagnetically induced transparency and absorption effects, as well as their associated characteristics. The results show that the control and manipulation of coherent optical responses are richer under three-photon conditions. The dispersion and group index profiles of the medium are studied, and the existence of four-wave mixing processes is also discussed.

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.
