Measurement and control of the interaction frequency shift in bosonic optical lattice clocks
J. P. Salvatierra, M. Barbiero, G. Bertaina +3
We report precise measurements of inter-level interactions in a bosonic optical lattice clock based on Sr atoms. We observe a nonlinear density dependence of the clock shift…
Analysis of spin-squeezing generation in cavity-coupled atomic ensembles with continuous measurements
A. Caprotti, M. Barbiero, M. G. Tarallo +2
We analyze the generation of spin-squeezed states via coupling of three-level atoms to an optical cavity and continuous quantum measurement of the transmitted cavity field in order…
Optically loaded Strontium lattice clock with a single multi-wavelength reference cavity
Matteo Barbiero, Davide Calonico, Filippo Levi +1
We report on the realization of a new compact strontium optical clock using a 2-D magneto-optical-trap (2D-MOT) as cold atomic source and a multi-wavelength cavity as the frequency…
A Sideband-Enhanced Cold Atomic Source For Optical Clocks
Matteo Barbiero, Marco G. Tarallo, Davide Calonico +3
We demonstrate the enhancement and optimization of a cold strontium atomic beam from a two-dimensional magneto-optical trap (2D-MOT) transversely loaded from a collimated atomic be…
Production of large Bose-Einstein condensates in a magnetic-shield-compatible hybrid trap
Giacomo Colzi, Eleonora Fava, Matteo Barbiero +3
We describe the production of large Bose-Einstein condensates in a hybrid trap characterized by a weak magnetic field quadrupole and a tightly focused infrare…
Observation of a Spinning Top in a Bose-Einstein Condensate
R. N. Bisset, S. Serafini, E. Iseni +5
Boundaries strongly affect the behavior of quantized vortices in Bose-Einstein condensates, a phenomenon particularly evident in elongated cigar-shaped traps where vortices tend to…
Dynamics and interaction of vortex lines in an elongated Bose-Einstein condensate
Simone Serafini, Matteo Barbiero, Michele Debortoli +5
We study the real-time dynamics of vortex lines in a large elongated Bose-Einstein condensate (BEC) of sodium atoms using a stroboscopic technique. Vortices are spontaneously produ…
