…we work with highly magnetic Erbium and Dysprosium atoms, which we cool to Nanokelvin temperatures in oder to explore the fascinating physics of the quantum world.

All our experiments are carried out at pressures of 10^(-11) mbar. In order to achieve these ultrahigh vacuums, carefully designed chambers need to be machined and assembled.

In order to trap and cool Erbium and Dysprosium in magneto optical traps, we use one of their narrow-linewidth transitions. These transitions need yellow laser light for Erbium and red one for Dysprosium.

In order to investigate quamtumphysics, we need high power lasers to trap atoms.  In our experiments we utilise for example green light to realise an optical lattice in which the atoms can be arranged on a periodic crystal structure.
