Heisenberg uncertainty of spatially gated electromagnetic fields

Abstract

Overview

The study introduces a Heisenberg uncertainty relation specifically derived for spatially-gated electric and magnetic field fluctuations.

Findings

• The analysis shows that uncertainty increases as gating sizes decrease, emphasizing the quantum nature of electromagnetic fields in confined spaces.
• The potential to optimize the state of light by minimizing electric field fluctuations at the expense of magnetic fluctuations or vice versa is discussed.
• Alternative methods without gating, such as interacting with a nanostructure, are suggested for realizing spatial confinements and quantum fields.

Conclusion

This study could pave the way for advancements in nonlinear spectroscopy of nanostructures, optical cavities, and detection of chiral signals, all crucial for EMF safety considerations in confined environments.
