Dissipation in the helium II film
(University of St Andrews, 1980) - ThesisThe theories that have been presented to explain the properties of liquid helium are reviewed. The existence of vortex lines and their importance to the dissipation in helium II are emphasised leading to a summary of the ... -
Continuous-wave optical parametric oscillators pumped by external cavity diode lasers
(University of St Andrews, 2002) - ThesisIn this thesis, high spatial, high spectral quality, ultra stable external cavity diode laser (ECDL) sources and continuous-wave optical parametric oscillators (cw OPOs) are designed, constructed and investigated. The ECDL ... -
Superselection rules, quantisation by parts and point interactions
(University of St Andrews, 2000) - ThesisThis thesis is concerned with the origination and development of mathematical tools, formalisms and idealised physical models, for the analysis of superselection rules and point interactions in quantum theory. We begin by ... -
A paramagnetic resonance spectrometer for the investigation of free radical species in solids at low temperatures
(University of St Andrews, 1961) - Thesis -
Helium II film transfer
(University of St Andrews, 1966) - ThesisHelium, the lightest of the noble gases, is the most difficult of all to liquify. Despite this, since the first liquefaction of helium by Kamerlingh Onnes (1908) the properties of the liquid have been extensively investigated. ...
