My name is Sofia Qvarfort. I am an EPSRC Doctoral Prize Fellow based at Imperial College London and University College London.
My current work involves measurements of gravitational parameters using quantum optomechanical systems, mathematical methods for nonlinear quantum systems and the estimation and measurement of entanglement as generated through gravity.
See my full list of my publications on Google Scholar. What follows is a short summary of my research and research interests.
Optomechanics and gravity
Optomechanical systems have been found to be excellent sensors and have been used for a variety of things. In my research, we looked at whether optomechanical systems can be used to measure gravitational acceleration. We found that they in theory perform as well as other systems, such as conventional gravimeter systems and atom interferometry systems.
Mathematical methods for optomechanical systems
Treating optomechanical systems is difficult, both analytically and numerically. This is mainly due to the non-linear term present in the optomechanical Hamiltonian. In collaboration with David Bruschi, we have developed and applied a toolbox of matheamtical methods that has allowed us to model a family of optomechanical Hamiltonians analytically. We hope that these methods will be of use for a wide range of applications, and we have a bunch of new ideas when it comes to their use.
Modelling and detecting gravitational entanglement
Is gravity a quantum force? One way to find out is by testing whether two systems can entangle by interacting with each other solely through gravity. A proposal by Sougato Bose detailed how this statement can be tested. Many experimental challenges remain, however, and we seek to make the theory more concrete.
