Quantum Analysis of Rydberg Atom Cavity Detector for Dark Matter Axion Search

Quantum analysis is made on the dynamical system consisting of the cosmic axions, photons and Rydberg atoms which are interacting in the resonant cavity. The atomic motion in a continuous incident beam is taken into account properly in order to make a precise estimate of the efficiency of the Rydberg atom cavity detector for dark matter axion search.

Quantum analysis of Rydberg atom cavity detector for dark matter axion search

Quantum calculations are developed on the dynamical system consisting of the cosmic axions, photons and Rydberg atoms which are interacting in the resonant microwave cavity. The time evolution is determined for the number of Rydberg atoms in the upper state which are excited by absorbing the axion-converted and thermal background photons. The calculations are made, in particular, by taking into account the actual experimental situation such as the motion and uniform distribution of the Rydberg atoms in the incident beam and also the spatial variation of the electric field in the cavity. Some e…

Probing new physics using Rydberg states of atomic hydrogen

We consider the role of high-lying Rydberg states of simple atomic systems such as $^1$H in setting constraints on physics beyond the Standard Model. We obtain highly accurate bound states energies for a hydrogen atom in the presence of an additional force carrier (the energy levels of the Hellmann potential). These results show that varying the size and shape of the Rydberg state by varying the quantum numbers provides a way to probe the range of new forces. By combining these results with the current state-of-the-art QED corrections, we determine a robust global constraint on new physics tha…
