Field-dependent anisotropic magnetoresistance and planar Hall effect in epitaxial magnetite thin films
N. Naftalis, A. Kaplan, M. Schultz +4
A systematic study of the temperature and magnetic field dependence of the longitudinal and transverse resistivities of epitaxial thin films of magnetite (Fe3O4) is reported. The a…
Atom-Optics Billiards: Non-linear dynamics with cold atoms in optical traps
Ariel Kaplan, Mikkel Andersen, Nir Friedman +1
We present a new experimental system (the ``atom-optics billiard'') and demonstrate chaotic and regular dynamics of cold, optically trapped atoms. We show that the softness of the…
Hyperfine Spectroscopy of Optically Trapped Atoms
A. Kaplan, M. F. Andersen, T. Grünzweig +1
We perform spectroscopy on the hyperfine splitting of Rb atoms trapped in far-off-resonance optical traps. The existence of a spatially dependent shift in the energy levels…
Decay of Quantum Correlations in Atom Optics Billiards with Chaotic and Mixed Dynamics
M. F. Andersen, A. Kaplan, T. Grünzweig +1
We perform echo spectroscopy on ultra cold atoms in atom optics billiards, to study their quantum dynamics. The detuning of the trapping laser is used to change the ``perturbation'…
Revivals of Coherence in Chaotic Atom-Optics Billiards
M. F. Andersen, T. Grünzweig, A. Kaplan +1
We investigate the coherence properties of thermal atoms confined in optical dipole traps where the underlying classical dynamics is chaotic. A perturbative expression derived for…
Suppression of Dephasing of Optically Trapped Atoms
M. F. Andersen, A. Kaplan, T. Grünzweig +1
Ultra-cold atoms trapped in an optical dipole trap and prepared in a coherent superposition of their hyperfine ground states, decohere as they interact with their environment. We d…
