Experimental consequences of mottness in high-temperature copper-oxide superconductors
It has been more than two decades since the copper-oxide high temperature superconductors were discovered. However, building a satisfactory theoretical framework to study these compounds still remains one of the major challenges in condensed matter physics. In addition to the mechanism of …

The doping and magnetic field dependence of the heat capacity of yttrium barium copper oxide superconductors
… contrast to what is observed in conventional superconductors when impurities are introduced. In order to make quantitative comparisons with various models and experiments, the heat capacity has been mathematically fit taking into account the effects of fluctuations and finite-size scaling. The …

Electronic light scattering in the layered cuprates
Light scattering studies of copper oxide superconductors and the parent insulator materials were performed. Dynamics of the copper oxygen planes were probed with plane-polarized photons, whereas plane-plane coupling was probed with the photons polarized perpendicular to the layers. In both cases …

Investigation of superconducting and non-superconducting phases of Na₀Ì£₃CoO₂·1.3H₂0
… and possible insight into the high-T[sub]c copper oxide superconductors as well as the possibility of other rich physical phenomenon. In this thesis, experimental evidence is presented illustrating the existence and properties of a previously unknown non-superconducting phase of …

Electronic structure and energetics of Fe-based superconductors: Effects of chemical and magnetic disorder in (Ba-X)(Fe-Y)2As2
The Fe-based superconductors (Fe-SCs) have reinvigorated the community of high-Tc researchers worldwide. Like copper-oxide superconductors (Cu-SCs), they are layered compounds in proximity to an antiferromagnetic (AFM) state. The Fe-SC systems are amenable to controlled chemical doping/alloying, …
