Laser cooling exploits the physics of light scattering to cool atomic and molecular gases to
close to absolute zero. It is the crucial initial step for essentially all atomic gas experiments in …

The invention of first laser in 1960 triggered the discovery of several new families of lasers. A
rich interplay of different lasing materials resulted in a far better understanding of the …

Ultracold atoms in optical lattices have great potential to contribute to a better understanding
of some of the most important issues in many-body physics, such as high-temperature …

We demonstrate site-resolved imaging of individual fermionic Li 6 atoms in a single layer of
a 3D optical lattice. To preserve the density distribution during fluorescence imaging, we …

The Pauli exclusion principle is one of the most fundamental manifestations of quantum
statistics. Here, we report on its local observation in a spin-polarized degenerate gas of …

Ultracold atoms confined to periodic potentials have proven to be a powerful tool for
quantum simulation of complex many-body systems. We confine fermions to one dimension …

Optical clocks benefit from tight atomic confinement enabling extended interrogation times
as well as Doppler-and recoil-free operation. However, these benefits come at the cost of …

We report on Bose-Einstein condensation in a gas of strontium atoms, using laser cooling as
the only cooling mechanism. The condensate is formed within a sample that is continuously …

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 …

Following the bichromatic sub-Doppler cooling scheme on the D 1 line of 40 K recently
demonstrated in Fernandes et al.[Europhys. Lett. 100, 63001 (2012) EULEEJ 0295-5075 …
