Light–matter interaction in the long-wavelength limit: no ground-state without dipole self-energy Open
Most theoretical studies for correlated light-matter systems are performed within the long-wavelength limit, i.e., the electromagnetic field is assumed to be spatially uniform. In this limit the so-called length-gauge transformation for a …

Matter Wave Lensing to Picokelvin Temperatures Open
Using a matter wave lens and a long time of flight, we cool an ensemble of ^{87}Rb atoms in two dimensions to an effective temperature of less than 50_{-30}^{+50} pK. A short pulse of red-detuned light generates an optical dipole force tha…

Self-bound dipolar droplet: A localized matter wave in free space Open
We demonstrate that a dipolar condensate can be prepared into a three-dimensional wavepacket that remains localized when released in free-space. Such self-bound states arise from the interplay of the two-body interactions and quantum fluct…

Relaxation in a Fuzzy Dark Matter Halo Open
Dark matter may be composed of light bosons, , with a de Broglie wavelength in typical galactic potentials. Such “fuzzy” dark matter (fuzzy dark matter (FDM)) behaves like cold dark matter (CDM) on much larger scales than the de Broglie wa…

Roadmap on structured waves Open
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave. Even the interference of two plane waves, or of a single i…

Entanglement-enhanced matter-wave interferometry in a high-finesse cavity Open
An ensemble of atoms can operate as a quantum sensor by placing atoms in a superposition of two different states. Upon measurement of the sensor, each atom is individually projected into one of the two states. Creating quantum correlations…
