Master-equation treatment of nonlinear optomechanical systems with optical loss
Sofia Qvarfort, Michael R. Vanner, P. F. Barker +1
Open-system dynamics play a key role in the experimental and theoretical study of cavity optomechanical systems. In many cases, the quantum Langevin equations have enabled excellen…
Optimal estimation of time-dependent gravitational fields with quantum optomechanical systems
Sofia Qvarfort, A. Douglas K. Plato, David Edward Bruschi +4
We study the fundamental sensitivity that can be achieved with an ideal optomechanical system in the nonlinear regime for measurements of time-dependent gravitational fields. Using…
Quantum metrology with optomechanical systems in the nonlinear regime
Sofia Qvarfort
This thesis focuses on the mathematical description and application of nonlinear cavity optomechanical systems. The first part is concerned with solving the dynamics of the standar…
Hydrogenic entanglement
Sofia Qvarfort, Sougato Bose, Alessio Serafini
Is there any entanglement in the simplest ubiquitous bound system? We study the solutions to the time-independent Schrödinger equation for a Hydrogenic system and devise two entang…
