Candidate theories to explain the anomalous spectroscopic signatures of atomic H in molecular H crystals
Kaden R. A. Hazzard, Erich J. Mueller
We analyze a number of proposed explanations for spectroscopic anomalies observed in atomic hydrogen defects embedded in a solid molecular hydrogen matrix. In particular, we critic…
On-site correlations in optical lattices: band mixing to coupled quantum Hall puddles
Kaden R. A. Hazzard, Erich J. Mueller
We extend the standard Bose-Hubbard model to capture arbitrarily strong on-site correlations. In addition to being important for quantitatively modeling experiments, for example, w…
Explanation of 100-fold reduction of spectral shifts for hydrogen on helium films
Kaden R. A. Hazzard, Erich J. Mueller
We show that helium film-mediated hydrogen-hydrogen interactions account for a two orders of magnitude discrepancy between previous theory and recent experiments on cold collision…
Hyperfine spectra of trapped Bosons in optical lattices
Kaden R. A. Hazzard, Erich J. Mueller
We calculate the interaction induced inhomogeneous broadening of spectral lines in a trapped Bose gas as a function of the depth of a three-dimensional cubic optical lattice. As ob…
