1848. Optical atomic clocks for gravitational wave physics

Invited Speaker / Conférencier invité

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 $4s^2{}^1{S}_0\to 4s3d{}^1{D}_2$ 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 nonlinearity

Shohini Ghose (Wilfrid Laurier University)

Theoretical 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...

1710. WITHDRAWN - Testing the feasibility of a solid-state system for a T-violation search experiment

CLOSED - Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

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...
