Hanbury Brown-Twiss Interferometry for Fractional and Integer Mott Phases
Ana Maria Rey, Indubala I. Satija, Charles W. Clark
Hanbury-Brown-Twiss interferometry (HBTI) is used to study integer and fractionally filled Mott Insulator (MI) phases in period-2 optical superlattices. In contrast to the quasimom…

Bogoliubov approach to superfluidity of atoms in an optical lattice
Ana Maria Rey, Keith Burnett, Robert Roth +3
We use the Bogoliubov theory of atoms in an optical lattice to study the approach to the Mott-insulator transition. We derive an explicit expression for the superfluid density base…
