In this popular science article we describe, how we managed to cool cesium atoms down to nK temperature range in the Laboratory for cold atoms located at the Jožef Stefan Institute. The cold atoms are a quantum matter that can be used to study quantum phenomena and for a development of new quantum technologies such as quantum sensors.

COBISS.SI-ID: 30369063Optically pumped magnetometers can be adapted for measurements of low frequency or quasi-DC signals to radio-frequency signals used in spectroscopy applications such as NQR and NMR. In comparison to SQUD magnetometers they do not need cryogenic cooling and are thus much easier to maintain.
