A population imbalance at different valleys of an electronic system lowers its effective rotational symmetry. We introduce a technique to measure such imbalance - a valley polarization - that exploits the unique fingerprints of this symmetry reductio

We discuss experiments to produce and detect atom correlations in a degenerate or nearly degenerate gas of neutral atoms. First we treat the atomic analog of the celebrated Hanbury Brown Twiss experiment, in which atom correlations result simply from

Brazilian beekeeping has gained prominence since the introduction of the Apís mellifera bees from Africa, a process that led to the hybridization of European species already existing in the country. The crossing between these species of bees promote
