Effective Photonic Modes and Quantization Volume for Cavity Quantum Electrodynamics
Michael A. D. Taylor, Pengfei Huo · 2024
Cavity light-matter coupling strength scales inversely on quantization volume, yet strong coupling occurs in Fabry-Perot cavities with macroscopic mirrors. We demystify this apparent contradiction by transforming the Hamiltonian into effective photonic modes, showing mirror-size independence.
