Compact Frequency Standard Based on an Intra-cavity Sample Cold Cesium Atoms
Stella Torres Muller, Daniel Varela Magalhaes, Renato Ferracini Alves +1
We have demonstrated the possibility for a compact frequency standard based on a sample of cold cesium atoms. In a cylindrical microwave cavity, the atoms are cooled and interrogat…
An Ultra-Stable Referenced Interrogation System in the Deep Ultraviolet for a Mercury Optical Lattice Clock
S. T. Dawkins, R. Chicireanu, M. Petersen +5
We have developed an ultra-stable source in the deep ultraviolet, suitable to fulfill the interrogation requirements of a future fully-operational lattice clock based on neutral me…
Doppler-free spectroscopy of the 1S0-3P0 optical clock transition in laser-cooled fermionic isotopes of neutral mercury
M. Petersen, R. Chicireanu, S. T. Dawkins +5
We have performed for the first time direct laser spectroscopy of the 1S0-3P0 optical clock transition at 265.6 nm in fermionic isotopes of neutral mercury laser-cooled in a magnet…
Observation of vortex formation in an oscillating trapped Bose-Einstein condensate
E. A. L. Henn, J. A. Seman, E. R. F. Ramos +7
We report on the observation of vortex formation in a Bose-Einstein condensate of Rb-87 atoms. Vortices are generated by superimposing an oscillating excitation to the trapping pot…
