Inelastic light scattering studies of quantum phase transitions in CuxTiSe2 and multiferroic TbMnO3
Abstract In this dissertation, inelastic (Raman) light scattering techniques are used to probe the temperature- and magnetic-field-induced phase transitions of two strongly correlated systems – the magnetoelectric multiferroic TbMnO3 and the layered dichalcogenide TiSe2 . In general, strongly …

Design of Resistivity Instrumentation for a He3 Cryostat and its Application to the Charge Density Wave Superconductor CuxTiSe2
… CDW and SC in the quasi-two dimensional material CuxTiSe2 is an interesting one which might reveal mechanisms in unconventional superconductors. A previous Brock graduate student grew crystals of CuxTiSe2. The precise doping of the samples was not known. In order to determine the doping parameter …

Inelastic Light Scattering Studies of Quantum Phase Transitions in Copper Titanium Diselenium and Multiferroic Terbium Manganese Trioxygen
… CDW state in TiSe2. Our Raman measurements on CuxTiSe2 show that the x-dependent mode softening exhibits identical scaling behavior to thermal mode softening in undoped TiSe2, suggesting that, like thermal mode softening, the x-dependent mode softening is also associated with a critical point. …

Collective modes in strongly correlated electron systems measured with momentum-resolved electron energy-loss spectroscopy
… pairs. As TiSe2 is doped with copper to form CuxTiSe2, the CDW transition temperature is suppressed and a superconducting dome emerges around x = 0.04. Using M-EELS, we find that the electronic mode softens near TC for very low doping values (x ≤ 0.004), but does not soften for doping values …
