Hypothesis
How do strong vibrational interactions affect the decoherence of molecular polaritons?
Conclusion
Strong vibrational interactions lead to multi-phonon processes that dominate the transition and dephasing rates in molecular polaritons.
Supporting Evidence
- Strong vibrational interactions suppress light-matter coupling.
- Multi-phonon processes dominate over single-phonon processes in strong coupling.
- Dark states act as population traps in the presence of many molecules.
Takeaway
When many molecules are in a cavity, their vibrations can change how they interact with light, making it harder for them to stay in sync.
Methodology
The study uses a variational polaron master equation to derive transition rates, dephasing rates, and Lamb shifts for many molecules in a resonant cavity.
Limitations
The model assumes identical molecules and neglects permanent dipole interactions.
