Zengshun Jiang, Kewei Sun, Yang Zhao, Konstantin Dorfman
TL;DR
This paper shows how phonon baths affect the transmission properties of metasurfaces in strong light-matter coupling regimes.
Contribution
The study introduces a method to control metasurface dissipation using phonon coupling in strong light-matter interactions.
Findings
Phonon coupling has minimal impact on dissipation in weak light-matter coupling.
Strong coupling significantly influences dissipation dynamics and narrows absorption spectrum linewidth.
Selected phonon modes near the center line control dissipation through few phonon channels.
Abstract
In the strong light–matter coupling regime, the transmission properties of metasurfaces have a remarkable similarity to those of typical two-level systems. In this work, we explore the absorption spectra of a metasurface coupled to a quantum phonon bath using the time-dependent variational principle and the flexible multi-D2 Davydov trial states. In the weak light–matter coupling regime, phonon coupling has minimal impact on system dissipation. However, in the strong coupling regime, it significantly influences dissipation dynamics. Additionally, a phonon bath with a selected number of strongly coupled modes near the phonon center line substantially narrows the absorption spectrum linewidth by controlling dissipation through a few phonon channels. These findings demonstrate the critical role of the phonon bath in shaping metasurface transmission properties, offering a promising approach…
