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 … Webb28 mars 2024 · The classical model for the scattering of light in Raman spectroscopy is a process in which the oscillating electric field ( E →) from a specific frequency of light () induces a dipole moment ( μ → i n d u c e d) in a molecule. The magnitude of the dipole moment depends on the molecules polarizability ( α ). (5.9.1) μ → i n d u c e d ...
