Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC)
as well as cold matter in general. Twenty years after the first realization of the BEC and 15 …

Many cold atom experiments rely on precise atom number detection, especially in the
context of quantum-enhanced metrology where effects at the single particle level are …

We use an effective one-dimensional Gross-Pitaevskii equation to study bright matter-wave
solitons held in a tightly confining toroidal trapping potential, in a rotating frame of reference …

We experimentally realize a Fabry–Perot-type optical microresonator near the cesium D2
line wavelength based on a tapered optical fiber, equipped with two fiber Bragg gratings that …

We experimentally address the significance of fidelity as a figure of merit in quantum state
reconstruction of discrete (DV) and continuous-variable (CV) quantum optical systems. In …

It is usually considered that the spectrum of an optical cavity coupled to an atomic medium
does not exhibit a normal-mode splitting unless the system satisfies the strong coupling …

Optical cavities are of central importance in numerous areas of physics, including precision
measurement, cavity optomechanics and cavity quantum electrodynamics. The …

Atom sensing based on Faraday rotation is an indispensable method for precision
measurements, universally suitable for both hot and cold atomic systems. Here we …

Using the strong dispersive coupling to a high-cooperativity cavity, we demonstrate fast and
non-destructive number-resolved detection of atoms in optical tweezers. We observe …

We propose a protocol for detecting a single atom in a cavity with the help of the χ (2)
nonlinear medium. When the χ (2) nonlinear medium is driven by an external laser field, the …
