Webb8 maj 2024 · Introduction. Raman spectroscopy is a characterization technique that detects bond vibrations that change the polarizability of the molecule. It is therefore a non-destructive technique and is suitable for examining both polymers and their additives. In general, Raman spectra can be used for identification purposes by referring to a … Webb13 apr. 2024 · We report continuous Raman sideband cooling of a long ion chain close to the motional ground state beyond the Lamb-Dicke (LD) regime. By driving multiple sideband transitions simultaneously, we show that nearly all axial modes of a 24-ion chain are cooled to the ground state, with an LD parameter as large as …
