Spectroscopy of correlated nanowires
… dissertation is concerned with spectroscopy of correlated nanowires, in particular carbon nanotubes and La_{2/3}Sr{1/3}MnO_3 (LSMO) nanowires. The technique of nonequilibrium superconducting tunnel spectroscopy is performed on carbon nanotube devices, and after subsequent deconvolution, the …

Monte Carlo explicitly correlated methods
… of instantaneous correlation through expensive correlated methods. The methods that have been developed to account for the incompleteness of the basis set, the R12/F12 methods, create high dimensional integrals that need to be separated with the resolution of the identity, are limited in their …

Spatially Correlated Model Selection (SCOMS)
In this dissertation, a variable selection method for spatial data is developed. It is assumed that the spatial process is non-stationary as a whole but is piece-wise stationary. The pieces where the spatial process is stationary are called regions. The variable selection approach accounts for two …

Distortion-Tolerant Communications with Correlated Information
… in wireless communication systems are often correlated in the spatial and/or temporal domains, and the correlation can be used to facilitate system designs and to improve system performance. First, the optimum</p> <p>node density, i.e., the optimum number of nodes in a unit area, is …

Engineering Band Structures in Correlated Oxides
The electronic structure of short period digital superlattices of two different phases depends strongly on the superlattice architecture. We have fabricated digital superlattices of super cells consisting of N layers of LaMnO3 and N layers of SrTiO 3, N=1, 2, 3, 8, and measured their optical …

Towards force-correlated ultrasound volume elastography
… images to measure organ volumes; and force-correlated three-dimensional elasticity maps. In order to allow for the simultaneous collection of tissue elasticity and compressive force, a shear wave elasticity enabled ultrasound probe was integrated with a load cell which measured the …

Correlated exciton dynamics in semiconductor nanostructures
… positively charged vacancy. Excitons can become correlated with other excitons, mutually influencing one another and exhibiting collective properties. The focus of this dissertation concerns the origins, effects, and control of correlated excitons in semiconductor nanostructures. Correlated …

Correlated evolution in experimental populations of yeast
… of lineages. Finally, I compared the direct and correlated responses to selection in both glucose and galactose in a nested reciprocal selection experimental design. This analysis revealed that (1) better adapted clones paid a larger cost of adaptation than poorly adapted ones; (2) direct and …

SPIN-ORBIT COUPLING IN STRONGLY CORRELATED SYSTEMS
… spin-orbit enhancement in a strongly correlated two-dimensional system. By our calculation, it is shown that a possible nonlinear Rashba effect can emerge in such a system. It can explain the presence of giant Rashba constants in some two-dimensional devices.

Spectral properties of strongly correlated electron systems
We investigate the single particle static and dynamic properties at zero temperature within the Hubbard an three-band-Hubbard model for the superconducting copper oxides. Based on the recently proposed self-energy functional approach (SFA) [M.Potthoff, Eur. Phys. J. B 32 429 (2003)], we present an …

Frustrated Magnetism in Strongly Correlated Electron Systems
… corresponding excitations in several strongly correlated electron systems, where exotic orderings can be induced as a result of magnetic frustration and quantum fluctuations. We show that emergent spin textures can arise close to a magnetic field-induced quantum critical point, when the single …

Variational study of strongly correlated electronic models
… in understanding the physics of strongly correlated electronic models. In particular the two simplest models for strongly correlated electrons, namely the Hubbard and t−J models, have been the subject of in- tensive studies. In a milestone paper of 1987, P.W. Anderson proposed that a …
