Counting statistics for mesoscopic conductors with internal degrees of freedom.

We consider the transport of electrons passing through a mesoscopic device possessing internal dynamical quantum degrees of freedom. The mutual interaction between the system and the conduction electrons contributes to the current fluctuations, which we describe in terms of full counting statistics. We identify conditions where this discriminates coherent from incoherent internal dynamics and a...

We review the currrent cosmic parameter determinations of relevance to inflation using the WMAP-1year, Boomerang, CBI, Acbar and other CMB data. The basic steps in the pipelines which determine the bandpowers from the raw data from which these estimations are made are summarized. We forecast how the precision is likely to improve with more years of WMAP in combination with future ground-based e...

We consider Bose-Einstein condensation of massive electrically charged scalars in a uniform background of charged fermions. We focus on the case when the scalar condensate screens the background charge, while the net charge of the system resides on its boundary surface. A distinctive signature of this substance is that the photon acquires a Lorentz-violating mass in the bulk of the condensate. ...

The time dependence of nonclassical correlations is investigated for two fields (1, 2) generated by an ensemble of cold Cesium atoms via the protocol of Duan et al. [Nature 414, 413 (2001)]. The correlation function R(t1, t2) for the ratio of cross to auto-correlations for the (1, 2) fields at times (t1, t2) is found to have a maximum value R max = 292±57, which significantly violates the Cauch...
