Neutron stars, pulsars and superfluids
Neutron stars are compact objects formed during the core collapse of a supernova, attaining densities greater than that of an atomic nucleus. The extreme conditions in these objects give rise to many exotic states of matter including superfluidity, superconductivity, color superconductivity, exotic particles such as hyperons and extreme magnetic fields. Neutron stars are observed by astronomers as radio pulsars, binary x-ray pulsars, Magnetars and other objects. Theoretically explaining phenomena such as glitches, timing noise and quasi-periodic oscillations can help us understand the nature these extreme objects and shed light on the state of matter above nuclear densities, a regime that cannot be probed with terrestrial experiment
Atomic Force Microscopy and Microelectromechanical sensors
The invention of the Atomic Force Microscope (AFM) in the 1980’s ushered in a revolution in microscopy, in which the direct interaction of an atomically sharp cantilever tip suspended from a micro-cantilever beam with a sample facilitates imaging to unprecedented resolution. In Microelectromechanical sensor applications (MEMs), single molecule mass spectrometry can be achieved by measuring a small shift in a cantilever's resonance frequencies.
In many AFM and MEMs applications, biological and chemical samples are often of interest, which can only be studied when immersed in a liquid environment.
Detailed theoretical modelling of the fluid and cantilever interaction is required to calibrate these instruments for accurate force reconstruction and imaging.
