Gravitational wave (GW) astronomy has entered a new era with the direct detection of acoustic-band GW signals by laser interferometers. As with the electromagnetic spectrum, observing gravitational waves in a range of different frequency bands will yield complementary insights into the astrophysics of gravitating objects. Gravitational waves at micro-hertz to milli-hertz frequencies can be...

We report on progress towards the construction of an optical atomic clock based on the $4s^{2}\,^{1}S_{0}\rightarrow4s3d\,^{1}D_{2}$ two-photon transition in $^{40}\mathrm{Ca}$ atoms. Two-photon transitions are inherently Doppler and recoil free, which eliminates the need for tight confinement of the atoms during interrogation. This allows for a simplified design that can be made robust,...

1786. Self-assisted complete maximally hyperentangled state analysis via the cross-Kerr nonlinearityShohini Ghose (Wilfrid Laurier University)30/05/2017, 12:15Theoretical Physics / Physique théorique (DTP-DPT)Invited Speaker / Conférencier invité
We present two complete maximally hyperentangled state analysis protocols for photons entangled in the polarization and spatial-mode degrees of freedom. The first protocol is a hyperentangled Bell state analysis scheme for two photons, and the second is a hyperentangled Greenberger-Horne-Zeilinger (GHZ) state analysis scheme for three photons. In each scheme, a set of mutually orthogonal...

A new source of time-reversal symmetry violation (T-violation) is widely believed to be necessary to explain the matter-antimatter asymmetry of the universe. Searches for the existence of permanent electric dipole moments (EDMs) of atomic nuclei can probe new physics sources of T-violation at energy scales that are vastly beyond the reach of colliders. We are evaluating the feasibility of...
