Bridging the gap : stellar and gas kinematics from integral field spectroscopy and cosmological simulations
(University of St Andrews, 2021-06-21) - ThesisWe are now in an era of spatially resolved spectroscopic observations for thousands of galaxies. Labelled integral field spectroscopy, a natural product is detailed kinematics of both stars and gas enabling accurate ... -
Semiconductor diode lasers for picosecond pulse generation
(University of St Andrews, 2002) - ThesisThis thesis describes ultrashort pulse production techniques for semiconductor diode lasers. Three methodologies have been considered: active modelocking, gainswitching and forced Q-switching. The advantages and disadvantages ... -
Quantum interference effects : electromagnetically induced transparency and focusing
(University of St Andrews, 1997) - ThesisTheoretical and experimental studies of steady state quantum interference effects within an atomic vapour have been carried out. These include the effects of Electromagnetically Induced Transparency (E.I.T.), Electromagnetically ... -
Supersymmetric quantum field theories from induced representations
(University of St Andrews, 1989) - ThesisThis thesis investigates the application of the method of induced representations in supersymmetric quantum field theories. First, the main features of the theory of induced representations of Lie groups, Lie algebras and ... -
Theoretical treatments of phase transitions in systems of polyatomic molecules
(University of St Andrews, 1971) - ThesisAs is well known, the microscopic and macroscopic properties of a system of molecules may he linked by means of the canonical partition function of statistical mechanics. In principle, a knowledge of the intermolecular ...
