Helium-3 nanoscopic NMR

May 23, 2013 – 2:00 pm
  • Magnetic fingerprints of superfluid helium-3 - With their SQUIDs, low-temperature specialists of the Physikalisch-Technische Bundesanstalt have made it possible for the magnetic moments of atoms of the rare isotope 3He to be measured with extreme sensitivity. With the aid of these sensors, highly sensitive nuclear resonance spectrometers were developed which have now provided deep insights into the state of matter at extremely low temperatures. The results have been published in the current edition of the magazine Science.(10.1126/science.1233621)

    New "pendulum" for the ytterbium clock

    March 11, 2012 – 5:00 pm

    New "pendulum" for the ytterbium clock - At the Physikalisch-Technische Bundesanstalt, the optical Ytterbium clock has experienced an increase in accuracy. It is exact to 17 digits after the decimal point now. The scientists have succeeded in exciting a quantum-mechanically strongly "forbidden" transition of this ion and - in particular - in measuring it with extreme accuracy. The results are published in the scientific journal Physical Review Letters: N. Huntemann et al: High-accuracy optical clock based on the octupole transition in 171Yb+, Phys. Rev. Lett. DOI 108,090801 (2012)
