Atomic spectroscopy at interfaces (ex OCR)
Topics of interest:
Atomic vapour Spectroscopy in the vicinity of an opics of interestAtomic vapour Spectroscopy in the vicinity of an interface:
Fundamental study of the properties of a free atom in the vicinity of an interface. Casimir-Polder interaction between an atom and a dielectric surface at non-zero temperature in the presence of surface polariton modes.
Sub-micron confinement of alkali atoms within the interstitial regions of an opal (quasi periodic three-dimensional structure of nanospheres), or within ultra-thin vapour cells.
Theoretical study of the interaction between an atom and an optical field with a complex spatial structure at a wavelength scale (Laguerre-Gauss beams, and nano-optics), notably the coupling with nearly forbidden atomic transitions (beyond the electric dipole approximation, and chiral properties).
