Raman spectroscopy experiments show that the interaction ... to an electric field is so fast that the response to the phonon motion is adiabatic, that is, can be computed as if at any time the ...

The team performed synchrotron near-field spectroscopy on the thin strontium ... when an infrared photon is coupled with an optical phonon (a.k.a. a phonon that can emit or absorb light), then ...

(i) Coherent Phonon Spectroscopy (CPS), which enables to identify (planetary) materials by their coherent phonon fingerprint via detecting the modulation of the complex dielectric function in the time ...

Phonon renormalization in QDs: Sharp LO phonon sideband structure was observed in CuCl QDs using persistent hole-burning spectroscopy. The LO phonon frequency in the excited state of the QD is reduced ...

Figure 2. Spectroscopy of hBN showing phase (left) and amplitude (center) at different sample locations in the topography image (right). Figure 3. Near-field optical images using a spatio-spectral ...

Spatio-temporal optical control, optical antennas, surface plasmon and phonon polaritons, extreme nonlinear optics, strong light matter interaction. Scanning probe near-field optical microscopy and ...

Phonon-polaritons are a unique type of electromagnetic wave that occurs when light interacts with vibrations in a material's crystal lattice structure. These phonon-polariton waves exhibit several ...
