The single-top production cross section is one third that of the top-pair production cross section at the LHC. During the first year of data taking, assuming an average luminosity of 10cms and a CMS energy of 14 TeV, the determination of the major contributions to the total single-top cross section should be achievable. Comparisons between the measured cross sections and the theoretical predict...

Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by π through interaction with only one photon. Here, we demonstrate a large conditional cross-phase modulation between a signal field, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory. This...

High-resolution TEM is well-suited to characterizing nanocrystals, where lattice fringes serve as a source of structural information [1, 2]. For example, 3D lattice parameters can be measured from 2D lattice fringe images taken at as few as two different specimen orientations [3-6]. Recent work has shown that lattice fringe-visibility maps, a thin-specimen extension of bend-contour and channeli...

We describe a novel technique for performing a single-shot optical cross-correlation in nanowaveguides. Our scheme is based on four-wave mixing between two orthogonally polarized input signals propagating with different velocities due to polarization mode dispersion. The cross-correlation is determined by measuring the spectrum of the idler wave generated by the four-wave mixing process. © 2014...
