TOPIC: Detection of valence bond order of ultracold atoms in optical lattices by off-resonant scattering of cavity photons
Ultracold atoms loaded on optical lattices can provide unprecedented
experimental systems for the quantum simulations and manipulations
of many quantum phases and quantum phase transitions between these phases.
However, so far, how to detect these quantum phases and phase
transitions effectively and non-destructively remain an
outstanding challenge. We show that cavity enhanced off-resonant light
scattering from ultra-cold atoms loaded on optical
lattices can provide such a method. It can be used to detect not only
the well known superfluid and
Mott insulating phases and the superfluid to Mott transition,
but also other important phases such as charge density wave,
valence bond solid and several kinds of supersolids in one, two and
three dimensional optical lattices and quantum phases transitions
between these phases.
