Imaging the Mott Insulator Shells using Atomic Clock Shifts
Gretchen K. Campbell, Jongchul Mun, Micah Boyd +5
Microwave spectroscopy was used to probe the superfluid-Mott Insulator transition of a Bose-Einstein condensate in a 3D optical lattice. Using density dependent transition frequenc…
Photon recoil momentum in dispersive media
Gretchen K. Campbell, Aaron E. Leanhardt, Jongchul Mun +4
A systematic shift of the photon recoil due to the index of refraction of a dilute gas of atoms has been observed. The recoil frequency was determined with a two-pulse light gratin…
Dynamical Instability of a Doubly Quantized Vortex in a Bose-Einstein condensate
Y. Shin, M. Saba, M. Vengalattore +6
Doubly quantized vortices were topologically imprinted in Na condensates, and their time evolution was observed using a tomographic imaging technique. The decay into…
