Role of different type of sub-systems in doubly driven Lambda-system in 87Rb
Kanhaiya Pandey
The well known Lambda-system using two ground state hyperfine levels, F=1 and F=2 of 5S1/2 and one hyperfine level, F=2 of excited state of 5P3/2 of 87Rb has been recently studied…
Trapping and detection of single atoms using a spherical mirror
Arpan Roy, Andrew Bah Shen Jing, Murray D. Barrett
We fabricate a miniature spherical mirror for tightly focusing an optical dipole trap for neutral atoms. The mirror formation process is modelled to predict the dimensions for part…
Dipole-Dipole coupled double Rydberg molecules
Martin Kiffner, Hyunwook Park, Wenhui Li +1
We show that the dipole-dipole interaction between two Rydberg atoms can give rise to long range molecules. The binding potential arises from two states that converge to different…
Spectroscopy on a single trapped 137Ba+ ion for nuclear magnetic octupole moment determination
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We present precision measurements of the hyperfine intervals in the 5D3/2 manifold of a single trapped Barium ion, 137 Ba+ . Measurements of the hyperfine intervals are made betwee…
Self-Organization Threshold Scaling for Thermal Atoms Coupled to a Cavity
K. J. Arnold, M. P. Baden, M. D. Barrett
We make a detailed experimental study of the threshold for the self-organization of thermal 87Rb atoms coupled to a high-finesse cavity over a range of atom numbers and cavity detu…
Reconfigurable self-sufficient traps for ultracold atoms based on a superconducting square
M. Siercke, K. S. Chan, B. Zhang +3
We report on the trapping of ultracold atoms in the magnetic field formed entirely by persistent supercurrents induced in a thin film type-II superconducting square. The supercurre…
