Testing spontaneous wavefunction collapse with quantum electromechanics
Germain Tobar, Stefan Forstner, Arkady Fedorov +1
Theories of spontaneous wavefunction collapse offer an explanation of the possible breakdown of quantum mechanics for macroscopic systems. However, the challenge of resolving predi…
Microphotonic Forces From Superfluid Flow
D. L. McAuslan, G. I. Harris, C. Baker +4
In cavity optomechanics, radiation pressure and photothermal forces are widely utilized to cool and control micromechanical motion, with applications ranging from precision sensing…
Laser cooling and control of excitations in superfluid helium
G. I. Harris, D. L. McAuslan, E. Sheridan +3
Superfluidity is an emergent quantum phenomenon which arises due to strong interactions between elementary excitations in liquid helium. These excitations have been probed with gre…
Position Estimation of a Parametrically Driven Optomechanical System
Alex Szorkovszky, Andrew C. Doherty, Glen I. Harris +1
We study the position estimation of a mechanical oscillator undergoing both detuned parametric amplification and continuous quantum measurement. This model, which can be utilised t…
Mechanical squeezing via parametric amplification and weak measurement
Alex Szorkovszky, Andrew C. Doherty, Glen I. Harris +1
Nonlinear forces allow motion of a mechanical oscillator to be squeezed below the zero-point motion. Of existing methods, mechanical parametric amplification is relatively accessib…
