An atom in front of a surface is one of the simplest and fundamental problem in physics. Yet,
it allows testing quantum electrodynamics, while providing potential platforms and interfaces …

We present an experimental measurement of the cooperative Lamb shift and the Lorentz
shift using a nanothickness atomic vapor layer with tunable thickness and atomic density …

We present a computer program and underlying model to calculate the electric susceptibility
of a gas, which is essential to predict its absorptive and dispersive properties. Our program …

Transmission spectroscopy in an ultrathin vapor cell, which has been recently demonstrated
as a new method of sub-Doppler spectroscopy in the optical domain, is revisited. We show …

In a thin cell of dilute vapour, the absorption spectrum exhibits sub-Doppler features due to
the relative enhancement of the slow atom contribution, with respect to the transient nature …

Miniaturizing and integrating atomic vapor cells is widely investigated for the purposes of
fundamental measurements and technological applications such as quantum sensing …

This chapter deals with atom-wall interaction occurring in the “long-range” regime (typical
distances: 1–1000 nm), when the electromagnetic fluctuations of an isolated atom are …

The van der Waals atom-surface attraction, scaling as C 3 z− 3 for z the atom-surface
distance, is expected to be valid in the distance range 1–1000 nm, covering 8–10 orders of …

Atom-light interactions in micro-and nanoscale systems hold great promise for alternative
technologies based on integrated emitters and optical modes. We present the design …

We report on the observation of Rabi oscillations to a Rydberg state on a time scale below 1
ns in thermal rubidium vapor. We use a bandwidth-limited pulsed excitation and observe up …
