\nConnecting Atoms and Nanophotonics: Spectroscopy of atoms under confinement<\/p>\n
\u8b1b\u6f14\u5185\u5bb9\uff1a
\n\u00a0\u00a0The talk will describe our activities in Laboratoire de\u3000physique des lasers at Paris13U.-Sorbonne-Paris-Cit\u00e9 (Villetaneuse campus), which combine the power of high resolution laser spectroscopy of atoms with specific effects associated to a confinement at a sub-wavelength scale.
\nThis should make atomic vapours of interest for the\u3000possibilities offered by nanotechnologies. We show that atomic vapours can be confined in micro- or nanocells (thin slice of vapour, and one dimensional confinement), or even to the voids region of an artificial opal of glass
\nnanospheres, hence realizing a three dimensional\u3000confinement. Moreover, in spite of the thermal motion in the atomic vapour, sub-Doppler features are observed even in the frame of linear spectroscopy, which are attributed to transient effects induced by the confinement.<\/p>\n
When exploring a distance to a surface smaller than ~100 nm, the fundamental atom-surface interaction (van der Waals electrostatic regime of the Casimir-Polder\u3000interaction), which is a signature of vacuum fluctuations, induces shifts and distortions of the atomic lineshapes,
\nfrom which this atom-surface interaction can be measured. Our most recent measurements demonstrate a large increase of this interaction with the temperature of the vacuum, owing to a thermal excitation of surface modes, which couple with atomic transitions.<\/p>\n","protected":false},"excerpt":{"rendered":"
