High-sensitivity gravity measurements are essential for environmental monitoring, natural resource exploration, and national security. Quantum gravimeters utilizing cold-atom interferometers have demonstrated high levels of accuracy, sensitivity, and long-term stability that outperforms traditional gravimeters based on falling corner cubes. We present improvements to the detection system of...

The matter-antimatter asymmetry is a long standing problem in physics. Sakharov showed that one requirement to explain this asymmetry is CP violation. To date there has not been sufficient CP violation observed in the Standard Model to fulfill this condition. We propose using novel FrAg molecules which are highly sensitive to hadronic CP violating physics to look for the Fr nuclear Schiff...

Hawking radiation is a quantum phenomenon arising from event horizons but is probably impossible to observe in its original astrophysical context. An alternative is to study an analogue system such as a Bose-Einstein condensate (BEC) where event horizons can occur in regions where the BEC flows faster than the speed of sound in the system, and phonons within the condensate play the role of...

Cold atoms in optical lattices can be used as quantum simulators to study the temporal evolution of quantum systems, which has lead to increasing interest in the out-of-equilibrium dynamics of bosons in optical lattices. Adding a second species of bosons introduces a wide range of novel quantum phases and provides a platform to explore analogues of spin systems. We study the Bose-Hubbard model...

817. Emergent Spacetime Geometries in Bose–Einstein Condensates: From Spherical Refocusing to FLRW Analogues

Atomic Bose-Einstein condensates (BECs) provide a versatile platform for simulating curved spacetimes via their emergent acoustic metrics. By tailoring the trapping potential, one can realize inhomogeneous density profiles that generate effective geometries conformal to a sphere or a hyperboloid. In the spherical case, phonons follow closed geodesics and refocus at antipodal points, echoing...

608. Topological Control of Vortices via Dynamical Instabilities

Nonequilibrium driving can generate strongly asymmetric responses even in systems without net bias or static symmetry breaking. We consider a framework for controlling vortices in a Bose–Einstein condensate confined to a ring trap through dynamical instabilities. When the system is periodically driven across an instability threshold, the resulting nonlinear response produces asymmetric growth...
