Scanning electron microscopy of cold gases

, 2015
Ultracold quantum gases offer unique possibilities to study interacting many-body quantum systems. Probing and manipulating such systems with ever increasing degree of control requires novel experimental techniques. Scanning electron microscopy is a high

Imaging the collective excitations of an ultracold gas using statistical correlations

New Journal of Physics, 2014
Advanced data analysis techniques have proved to be crucial for extracting information from noisy images. Here we show that principal component analysis can be successfully applied to ultracold gases to unveil their collective excitations.

Observation of a Halo Trimer in an Ultracold Bose-Fermi Mixture

Physical Review X
The quantum mechanics of three interacting particles gives rise to fundamental and universal phenomena, such as the staircase of Efimov trimers predicted in the context of nuclear physics and observed in ultracold gases.

Gauge fields for ultracold atoms in optical superlattices

, 2010
We present a scheme that produces a strong U(1)-like gauge field on cold atoms confined in a two-dimensional square optical lattice. Our proposal relies on two essential features, a long-lived metastable excited state that exists for alkaline-earth or ...

Many-Body Physics of Low-Density Dipolar Bosons in Box Potentials

Condensed Matter, 2019
Crystallization is a generic phenomenon in classical and quantum mechanics arising in a variety of physical systems. In this work, we focus on a specific platform, ultracold dipolar bosons, which can be realized in experiments with dilute gases.

Focus on out-of-equilibrium dynamics in strongly interacting one-dimensional systems

New Journal of Physics, 2014
In the past few years, there have been significant advances in understanding out-of-equilibrium dynamics in strongly interacting many-particle quantum systems. This is the case for 1D dynamics, where experimental advances—both with ultracold atomic gases
