Probing Interactions between Ultracold Fermions
G. K. Campbell, M. M. Boyd, J. W. Thomsen +12
At ultracold temperatures, the Pauli exclusion principle suppresses collisions between identical fermions. This has motivated the development of atomic clocks using fermionic isoto…
The absolute frequency of the 87Sr optical clock transition
Gretchen K. Campbell, Andrew D. Ludlow, Sebastian Blatt +10
The absolute frequency of the 1S0-3P0 clock transition of 87Sr has been measured to be 429 228 004 229 873.65 (37) Hz using lattice-confined atoms, where the fractional uncertainty…
Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock
A. D. Ludlow, T. Zelevinsky, G. K. Campbell +16
Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comp…
The XMM-Newton view of the Crab
M. G. F. Kirsch, G. Schoenherr, E. Kendziorra +7
We discuss the current X-ray view of the Crab Nebula and Pulsar, summarising our analysis of observations of the source with the EPIC-pn camera on board the XMM-Newton observatory.…
