A Bright Solitonic Matter-Wave Interferometer
Gordon D. McDonald, Carlos C. N. Kuhn, Kyle S. Hardman +6
We present the first realisation of a solitonic atom interferometer. A Bose-Einstein condensate of atoms of rubidium-85 is loaded into a horizontal optical waveguide.…
Precision atomic gravimeter based on Bragg diffraction
P. A. Altin, M. T. Johnsson, V. Negnevitsky +10
We present a precision gravimeter based on coherent Bragg diffraction of freely falling cold atoms. Traditionally, atomic gravimeters have used stimulated Raman transitions to sepa…
Why momentum width matters for atom interferometry with Bragg pulses
Stuart S. Szigeti, John E. Debs, Joseph J. Hope +2
We theoretically consider the effect of the atomic source's momentum width on the efficiency of Bragg mirrors and beamsplitters and, more generally, on the phase sensitivity of Bra…
Cold atom gravimetry with a Bose-Einstein Condensate
J. E. Debs, P. A. Altin, T. H. Barter +6
We present a cold atom gravimeter operating with a sample of Bose-condensed Rubidium-87 atoms. Using a Mach-Zehnder configuration with the two arms separated by a two-photon Bragg…
Optically trapped atom interferometry using the clock transition of large Rb-87 Bose-Einstein condensates
P. A. Altin, G. McDonald, D. Döring +7
We present a Ramsey-type atom interferometer operating with an optically trapped sample of 10^6 Bose-condensed Rb-87 atoms. The optical trap allows us to couple the |F =1, mF =0>\r…
Quantum projection noise limited interferometry with coherent atoms in a Ramsey type setup
D. Döring, G. McDonald, J. E. Debs +5
Every measurement of the population in an uncorrelated ensemble of two-level systems is limited by what is known as the quantum projection noise limit. Here, we present quantum pro…
