Noise Correlations of Hard-core Bosons: Quantum Coherence and Symmetry Breaking
Ana Maria Rey, Indubala I Satija, Charles W Clark
Noise correlations, such as those observable in the time of flight images of a released cloud, are calculated for hard-core bosonic (HCB) atoms. We find that the standard mapping o…
Theory of Feshbach molecule formation in a dilute gas during a magnetic field ramp
J. E. Williams, N. Nygaard, C. W. Clark
Starting with coupled atom-molecule Boltzmann equations, we develop a simplified model to understand molecule formation observed in recent experiments. Our theory predicts several…
Frequency-dependent polarizabilities of alkali atoms from ultraviolet through infrared spectral regions
M. S. Safronova, Bindiya Arora, Charles W. Clark
We present results of first-principles calculations of the frequency-dependent polarizabilities of all alkali atoms for light in the wavelength range 300-1600 nm, with particular a…
Noise Correlations and Quantum Coherence in Hard-core Bosons in One-dimensional Lattices
Ana Maria Rey, Indubala I Satija, Charles W Clark
Noise correlations, such as those observable in the time of flight images of a released cloud, are calculated for hard-core bosonic (HCB) atoms. We find that the standard mapping o…
Pseudo-fermionization of 1-D bosons in optical lattices
Guido Pupillo, Ana Maria Rey, Carl J. Williams +1
We present a model that generalizes the Bose-Fermi mapping for strongly correlated 1D bosons in an optical lattice, to cases in which the average number of atoms per site is larger…
Ultracold atoms confined in an optical lattice plus parabolic potential: a closed-form approach
Ana Maria Rey, Guido Pupillo, Charles W. Clark +1
We discuss interacting and non-interacting one dimensional atomic systems trapped in an optical lattice plus a parabolic potential. We show that, in the tight-binding approximation…
