Probing the Circular Unruh Effect with Cavity-Controlled Lamb Shifts
Yan Peng, Jiawei Hu, Hongwei Yu
The Unruh effect predicts that accelerated observers perceive the inertial vacuum as populated by particles, providing a flat-spacetime analogue of Hawking radiation. Its direct ob…
Acceleration-induced spectral blind spots in stimulated atomic transitions
Jiawei Hu, Hongwei Yu
Stimulated transitions are among the most fundamental processes in light-matter interaction, underlying resonant absorption and emission in atomic systems. Here we show that unifor…
Significant modifications of Lamb shift at small centripetal accelerations
Yan Peng, Jiawei Hu, Hongwei Yu
We investigate the Lamb shift of centripetally accelerated atoms coupled to electromagnetic vacuum fluctuations. Focusing on a very small orbital radius (so that the tangential spe…
Extensive manipulation of transition rates and substantial population inversion of rotating atoms inside a cavity
Yan Peng, Yuebing Zhou, Jiawei Hu +1
We investigate the transition rates of a centripetally accelerated atom inside a high-quality cavity and show that they can be extensively tuned by adjusting the cavity resonance a…
Spontaneous excitation of a centripetally accelerated atom coupled to electromagnetic vacuum fluctuations near a reflecting boundary
Yan Peng, Jiawei Hu, Hongwei Yu
We investigate the rate of change of the mean atomic energy for centripetally accelerated atoms interacting with electromagnetic vacuum fluctuations near a reflecting boundary, usi…
Molecular entanglement as a signature of the Unruh effect
Yuebing Zhou, Jiawei Hu, Hongwei Yu
The Unruh effect predicts that a uniformly accelerated observer perceives the vacuum seen by an inertial observer as a thermal bath at a temperature proportional to its proper acce…
