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…
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…
Quantum-jump vs stochastic Schrödinger dynamics for Gaussian states with quadratic Hamiltonians and linear Lindbladians
Robson Christie, Jessica Eastman, Roman Schubert +1
The dynamics of Gaussian states for open quantum systems described by Lindblad equations can be solved analytically for systems with quadratic Hamiltonians and linear Lindbladians,…
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…
Tuning quantum measurements to control chaos
Jessica K. Eastman, Joseph J. Hope, André R. R. Carvalho
Environment-induced decoherence has long been recognised as being of crucial importance in the study of chaos in quantum systems. In particular, the exact form and strength of the…
