the reionization of cosmic hydrogen, left over from the big bang, increased its temperature to > ~ 1. e4 k. this photo - heating resulted in an increase of the minimum mass of galaxies and hence a suppression of the cosmic star formation rate. the affected population of dwarf galaxies included the progenitors of massiv... | arxiv:astro-ph/0510421 |
we suggest a scheme to reconstruct the covariance matrix of a two - mode state using a single homodyne detector plus a polarizing beam splitter and a polarization rotator. it can be used to fully characterize bipartite gaussian states and to extract relevant informations on generic states. | arxiv:quant-ph/0509180 |
let $ n ( x, y ) $ denote the number of integers $ n \ le x $ which are divisible by a shifted prime $ p - 1 $ with $ p > y $, $ p $ prime. improving upon recent bounds of mcnew, pollack and pomerance, we establish the exact order of growth of $ n ( x, y ) $ for all $ x \ ge 2y \ ge 4 $. | arxiv:1604.00281 |
