A two-year intercomparison of CW focusing wind lidar and tall mast wind measurements at Cabauw
Steven Knoop, Fred Bosveld, Marijn de Haij +1
A two-year measurement campaign of the ZephIR 300 vertical profiling continuous-wave (CW) focusing wind lidar has been carried out by the Royal Netherlands Meteorological Institute…
Wind LiDAR measurement campaign at CESAR Observatory in Cabauw: preliminary results
Steven Knoop, Willem Koetse, Fred Bosveld
A two-year verification campaign of the ZephIR~300 vertical profiling wind LiDAR has recently been started by the Royal Netherlands Meteorological Institute (KNMI) at the CESAR Obs…
An ultracold, optically trapped mixture of {87}Rb and metastable {4}He atoms
Adonis Silva Flores, Hari Prasad Mishra, Wim Vassen +1
We report on the realization of an ultracold (<25~muK) mixture of rubidium ({87}Rb) and metastable triplet helium ({4}He) in an optical dipole trap. Our scheme involves laser cooli…
Quantum-State Controlled Penning Ionization Reactions between Ultracold Alkali and Metastable Helium Atoms
Adonis Silva Flores, Wim Vassen, Steven Knoop
In an ultracold, optically trapped mixture of Rb and metastable triplet He atoms we have studied trap loss for different spin-state combinations, for which interspecies…
Simple method for producing Bose-Einstein condensates of metastable helium using a single beam optical dipole trap
Adonis Silva Flores, Hari Prasad Mishra, Wim Vassen +1
We demonstrate a simple scheme to reach Bose-Einstein condensation (BEC) of metastable triplet helium atoms using a single beam optical dipole trap with moderate power of less than…
Ab initio interaction potentials and scattering lengths for ultracold mixtures of metastable helium and alkali-metal atoms
Dariusz Kȩdziera, Łukasz Mentel, Piotr S. Żuchowski +1
We have obtained accurate ab initio quartet potentials for the diatomic metastable triplet helium + alkali-metal (Li, Na, K, Rb) systems, using all-electron restricted open-shell c…
