WebDec 14, 2016 · Monitoring Electron-Photon Dressing in WSe 2 Optical pumping of solids creates a nonequilibrium electronic structure where electrons and photons combine to form quasiparticles of dressed electronic states. The resulting shift of electronic levels is known as the optical Stark effect, visible as a red shift in the optical spectrum. Here we show … WebApr 22, 2024 · This electron-phonon coupling results in a so-called phonon dressing of many-body states which in turn impacts on the facilitation dynamics. In our theoretical study we focus on a scenario in which all energy scales are sufficiently separated such that a perturbative treatment of the coupling between electronic and vibrational states is possible.
WebPhonon interactions in solid-state photonics systems cause intrinsic quantum decoherence and often present the limiting factor in emerging quantum technology. Due to recent … Webmomentum-dependent electron–phonon coupling in SnSe, as is expected from Fröhlich coupling in a polar lattice (16). However, the ultrafast diffuse scattering signals also show clear signatures of the “phonon dressing” (lattice distortion) that drives photo-carrier localization and polaron formation (Fig. 1 D–F), even
WebUsing a two-temperature model, we illustrate that phonon dressing can effectively break the original spatial symmetries and consequently alter the optical selection rules. We provide a geometrical interpretation for this effect.
