Invited talk

Atomic clocks provide precise timing signals critical to modern infrastructure including Communication networks, power infrastructure, and positioning, navigation and timing (PNT) services such as the Global Navigation Satellite System (GNSS). While these clocks have traditionally used microwaves to drive atomic transitions, recent research efforts have utilised lasers due to the promise of...

Contributed Oral

We present an atomtronic toolbox to study quantum transport phenomena and quantum scattering problems using Bose-Einstein condensates (BECs) in spatially and temporally modulated optical potentials. We have recently applied this apparatus to investigating atomic Josephson junctions.

Our platform can apply an arbitrary optical potential to a BEC, using a two-axis acousto-optical deflector...

AIP | Atomic and Molecular Physics (ATMOP)

Contributed Oral

Coherent heterodyne detection methods present an opportunity for improved sensitivity in quantum sensing. Four wave mixing is a commonly used spectroscopic technique, with limited previous applications in magnetometry.
Using alkali vapour in a double lambda configuration we perform four wave mixing over the hyperfine states. By beating the probe and generated conjugate beams together at a...

627. Field Validations of Quantum-Enabled Navigation on Dynamic, Real-World Platforms

AIP | Atomic and Molecular Physics (ATMOP)

Contributed Oral

Quantum sensors utilizing atomic vapours can enable passive, GPS-free navigation through their exquisitely sensitive and stable measurements of inertial quantities and magnetic fields. These quantum measurements make bounded position-fixing possible in environments where GPS is unavailable or untrusted —irrespective of mission duration or distance travelled— through map matching against...

681. Tabletop particle physics with BaOH: Molecular structure theory for next-gen precision measurements of time-reversal symmetry violation

Contributed Oral

Despite decades of indisputable success, the Standard Model (SM) of particle physics is known to be incomplete. Indeed, explaining the observed matter-antimatter asymmetry in the Universe, given equal generation of both during the Big Bang, remains one of the most pressing problems in theoretical physics. While the SM contains a source of charge-parity (CP) violation within the quark mixing...
