{getToc} $title={Table of Contents}

Summary

The article discusses the potential for open quantum dynamical effects, specifically frequency shifts, to constrain models of light scalar fields, such as chameleons and symmetrons. These effects are studied in the context of atom interferometry experiments.

Highlights

• The article considers the n = -4 chameleon and symmetron models.
• Frequency shifts are calculated using a quantum field theoretical method.
• The results indicate that symmetron-induced frequency shifts have the potential to constrain previously unreachable parts of the parameter space.
• Chameleon-induced frequency shifts are less promising for constraining new regions of the parameter space.
• The calculations assume a constant VEV and mass for the screened scalar fields.
• The article suggests that comparing experiments with different atom species could lead to new constraints.
• The results highlight the potential for open quantum dynamical effects to provide new insights into light scalar field models.

Key Insights

• The article demonstrates the importance of considering open quantum dynamical effects in the study of light scalar field models, as these effects can provide new avenues for constraining these models.
• The symmetron model is found to be more promising for constraining new regions of the parameter space using frequency shifts, particularly for values of μ above 10^4 eV.
• The chameleon model, on the other hand, is less promising for constraining new regions of the parameter space using frequency shifts, as the effects are found to be subleading.
• The article highlights the need for more sophisticated computational methods to confirm or amend the results, particularly for more realistic atomic systems.
• The results suggest that comparing experiments with different atom species could lead to new constraints on light scalar field models, providing a new avenue for experimental exploration.
• The article emphasizes the importance of considering the impact of the experimental setup on the screened scalar fields, particularly in the context of atom interferometry experiments.
• The study of open quantum dynamical effects in light scalar field models has the potential to provide new insights into these models and their potential applications in cosmology and particle physics.
