Surface-Induced Spectral Broadening during Efficient Two-Photon Excitation of Cold Atoms near an Optical Nanofiber
Yuan Jiang, Xiaodong Qi, Nicolás Vera Paz +5
We report the experimental observation of the Cs 6S to 6D single-frequency two-photon transition at low excitation power using an optic…
The Specification as Quality Gate: Three Hypotheses on AI-Assisted Code Review
Christo Zietsman
The dominant industry response to AI-generated code quality problems is to deploy AI reviewers. This paper argues that this response is structurally circular when executable specif…
Voltage and power-frequency electric field measurements with Rydberg-atom interferometry
Yingying Han, Changfa He, Zhenxiong Weng +3
We present a Rydberg-atom interferometry-based technique for voltage measurement between electrodes embedded in an atomic vapor cell, enabling the detection of weak voltages ($<0.1…
Phase-sensitive Rydberg-atom interferometry with Floquet electromagnetically induced transparency
Yingying Han, Changfa He, Peng Xu +3
We design a phase-sensitive Rydberg-atom interferometry by implementing Floquet electromagnetically induced transparency (FEIT). The FEIT mixes the sidebands of a Rydberg state ind…
Ferromagnetic Traps for Quasi-Continuous Operation of Optical Nanofiber Interfaces
Ruijuan Liu, Jinggu Wu, Yuan Jiang +2
A soft ferromagnetic plate uniformizes Tesla-level fields generated by attached permanent magnets, producing a smooth and electronically tunable surface field on the opposite side.…
Exceptional nexus in Bose-Einstein condensates with collective dissipation
Chenhao Wang, Nan Li, Jin Xie +6
In multistate non-Hermitian systems, higher-order exceptional points and exotic phenomena with no analogues in two-level systems arise. A paradigm is the exceptional nexus (EX), a…
Dynamical beats of short pulses in waveguide QED
Dianqiang Su, Yuan Jiang, Silvia Cardenas-Lopez +4
We study temporal oscillations, known as dynamical beats, developed by a propagating pulse due to its interaction with a near-resonant collective medium of Cs atoms randoml…
Optomechanical feedback cooling of a 5 mm-long torsional mode
Dianqiang Su, Yuan Jiang, Pablo Solano +3
We report three orders of magnitude optical cooling of the fundamental torsional mode of a 5 mm-long, 550 nm diameter optical nanofiber. The rotation of the nanofiber couples to th…
