Abstract

A study conducted by researchers at Central China Normal University in Wuhan, People's Republic of China, explores the effects of various factors on the performance of portable self-oscillating magnetometers. The researchers examined the impact of laser intensity, resonance detuning, radio frequency magnetic field, and atomic cell on the magnetometers' performance. By analyzing the influencing factors on the atomic magnetic resonance signal, the researchers were able to optimize the parameters of the magnetometers. The study provides valuable insights for improving the performance of these devices, which are widely used in fields such as biomedicine and remote sensing. [Extracted from the article]

Abstract

The entanglement property between two two-level atoms interacting with a stochastic field is studied. We analytically prove that when the correlation time κ -1 of the stochastic field is very short compared to the radiative lifetime γ -1 of the atom, the steady-state entanglement between the two atoms can appear. The concurrence characterizing the entanglement degree has also been calculated by using Monte Carlo simulation. It is shown that the correlation time has a strong effect on the entanglement. We also discuss the influence of strength of the stochastic process on the entanglement. The validity of the decorrelation approximation is also investigated. [ABSTRACT FROM AUTHOR]
