These observed doublet splittings, some as large as 70 kHz, were later...Go to contribution page

An essential part of the analysis is to understand the energy distribution and spectra of the recoil ions. After the $\beta$ decay...Go to contribution page

The 15N isotopic variety could be very important since it allows the knowledge of the 14N/15N ratio in the universe. Although lists of...Go to contribution page

Mrs Nafiseh Sang-Nourpour (Institute for Quantum Science and Technology, University of Calgary, Alberta T2N 1N4, Canada ; Photonics Group, Research Institute for Applied Physics and Astronomy, University of Tabriz, Tabriz 51665-163, Iran)17/06/2015, 14:30Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)We introduce a general theory for describing modes and characteristics of linear, homogeneous, isotropic waveguide materials and metamaterials with slab and cylindrical geometries. Our theory accommodates exotic media such as double-negative-index and near-zero-index metamaterials as special cases, and we demonstrate that our general theory exhibits electromagnetic duality that would...Go to contribution page

Nicolas Quesada (University of Toronto)17/06/2015, 14:45Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)Frequency conversion (FC) is one of the most common nonlinear processes used in quantum optics. This process has the property that the Hamiltonian that governs it does not commute with itself at different times, and hence time ordering becomes an important aspect in the description of its dynamics. Recently, it has been shown that the Magnus expansion provides an appropriate description of...Go to contribution page

Mr Ish Dhand (University of Calgary)17/06/2015, 15:00Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)We combine single- and two-photon interference procedures for characterizing any multichannel passive linear optical interferometer accurately and precisely. Accuracy is achieved by accounting for systematic errors due to spatiotemporal and polarization mode mismatch and estimating those mismatch parameters through calibrating on one known beam splitter. Enhanced precision is achieved by curve...Go to contribution page
