Developing a simulation tool to investigate a novel trapped two-state Bose-Einstein condensate Ramsey interferometer driven by dipole oscillations and gravitational sag
Anushka Thenuwara, Andrei Sidorov
We propose and explore the feasibility of a novel Ramsey interferometer created by a trapped two-state Bose-Einstein condensate (BEC) driven by dipole oscillations and gravitationa…
Ramsey interferometry in three-level and five-level systems of Bose-Einstein condensates
Anushka Thenuwara, Andrei Sidorov
Our work here presents the analytical expressions for a typical Ramsey interferometric sequence for a three- and a five-level system. The analytical expressions are derived startin…
Phase diffusion in trapped-atom interferometers
Valentin Ivannikov, Andrei I. Sidorov
We evaluate the performance and phase diffusion of trapped Rb atoms in an atom-chip sensor with Ramsey interferometry and Hahn's spin echo in the time and phase domains. We…
Trapping ultracold atoms at 100 nm from a chip surface in a 0.7-micrometer-period magnetic lattice
Yibo Wang, Tien Tran, Prince Surendran +6
We report the trapping of ultracold 87Rb atoms in a 0.7 micron-period 2D triangular magnetic lattice on an atom chip. The magnetic lattice is created by a lithographically patterne…
Probing degenerate two-level atomic media by coherent optical heterodyning
A. M. Akulshin, R. J. McLean, A. I. Sidorov +1
We analyze how light-induced coherent population oscillations and ground-state Zeeman coherence in an atomic medium with degenerate two-level transitions can modify spectra of appl…
Probing Zeeman coherence in nearly degenerate two-level atomic vapour with four-wave mixing
A. M. Akulshin, A. I. Sidorov, R. J. McLean +1
We present results of a study of four-wave mixing in Rb vapour with highly nonlinear susceptibility, using both homodyne and heterodyne detection. We demonstrate that the spectra h…
