Quantum simulations on square and triangular Hubbard models
… correlated region and the structure of the Fermi surface in this region will favor superconducting pairings with a certain type of symmetry. For the cuprate physics, a superconducting dome composed of d-wave pairings has been identified experimentally. We study the Hubbard model on square …

Pressure Tuned Magnetism in d- and f-Electron Materials
… of new states of matter, for example; the marginal Fermi Liquid and non Fermi Liquid states as well high T$_C$ cuprate and magnetically mediated superconductivity. In this thesis I present work on three materials in which it may be possible to tune the system through a magnetic QPT with the …

Characterization of collective phenomena in cuprate superconductors by momentum-resolved electron energy loss spectroscopy
… that extends out to ∼1 eV, consistent with a marginal Fermi liquid description of these materials. In addition, from our measurements of the static component of the charge susceptibility, we have discovered diffuse, short-range charge order in optimally doped Bi2212. Proximity to the charge …

Phenomenological phase-fluctuation model for the underdoped cuprates
… transition, after the inclusion of an additional marginal-Fermi-liquid scattering-rate in the optical conductivity formula. Finally, we calculated the static uniform diamagnetic susceptibility. It turned out that the precursor effects of the fluctuating diamagnetism above T_c are very small and …

Investigations of the Band Structure and Morphology of Nanostructured Surfaces
… I show that suspended graphene behaves as a marginal Fermi-liquid, with a quasiparticle lifetime which scales as (E - EF)-1; comparison with other graphene and graphite data is discussed. Image and surface states formed at the vacuum interface of a single crystal provide another example of a …
