In recent years, the ability of cold atom experiments to explore condensed-matter-related
questions has dramatically progressed. Transport experiments, in particular, have expanded …

An optical cavity enhances the interaction between atoms and light, and the rate of coherent
atom–photon coupling can be made larger than all decoherence rates of the system. For …

The Unruh effect predicts a thermal response for an accelerated detector moving through the
vacuum. Here we propose an interferometric scheme to observe an analogue of the circular …

The development of a fiber-based, tunable optical cavity with open access is reported. The
cavity is of the Fabry-Pérot type and is formed with miniature spherical mirrors positioned on …

We describe an easily implementable method for non-destructive measurements of ultracold
atomic clouds based on dark field imaging of spatially resolved Faraday rotation. The signal …

We employ heterodyne interferometry to investigate the effect of a single organic molecule
on the phase of a propagating laser beam. We report on the first phase-contrast images of …

We review our experiments on quantum information processing with neutral atoms in optical
lattices and magnetic microtraps. Atoms in an optical lattice in the Mott insulator regime …

The fluctuations in thermodynamic and transport properties in many-body systems gain
importance as the number of constituent particles is reduced. Ultracold atomic gases provide …

We dispersively interface an ensemble of 1000 atoms trapped in the evanescent field
surrounding a tapered optical nanofiber. This method relies on the azimuthally asymmetric …

We report on the fast production and weakly destructive detection of a Fermi gas with
tunable interactions in a high finesse cavity. The cavity is used both with far off-resonant light …
