Characterizing Multimode Effects in a Guided Matterwave Gyroscope
Jessica K. Eastman, Ellen Zheng, Stuart S. Szigeti +1
We theoretically investigate the performance of a compact matterwave vortex gyroscope formed by a two-component Bose-Einstein condensate in a toroidal potential. Unlike conventiona…
Atom Interferometry with Transverse Optical Modes
Ryan Husband, Ryan J. Thomas, Yosri Ben-Aïcha +10
We experimentally demonstrate atom interferometry using the transverse phase profile of an optical mode. As proof-of-principle, we use the helical phase windings of Hypergeometric…
Vortex Propagation in Orbital Angular Momentum Beams and the Effects of a Limited Aperture
Ryan Husband, Jessica Eastman, Ryan J. Thomas +4
When generating light with orbital angular momentum by imprinting orbital phase onto a standard Gaussian beam, it is often assumed that the propagation of the generated spatial mod…
Quantum Tunnelling and Thermally Driven Transitions in a Double Well Potential at Finite Temperature
Robson Christie, Jessica Eastman
We explore dissipative quantum tunnelling, a phenomenon central to various physical and chemical processes, using a double-well potential model. This paper aims to bridge gaps in u…
The effects of amplification of fluctuation energy scale by quantum measurement choice on quantum chaotic systems: Semiclassical analysis
S. Greenfield, Y. Shi, J. K. Eastman +2
Measurement choices in weakly-measured open quantum systems can affect quantum trajectory chaos. We consider this scenario semi-classically and show that measurement acts as nonlin…
Controlling chaos in the quantum regime using adaptive measurements
Jessica K. Eastman, Stuart S. Szigeti, Joseph J. Hope +1
The continuous monitoring of a quantum system strongly influences the emergence of chaotic dynamics near the transition from the quantum regime to the classical regime. Here we pre…
