We then consider systems in which the pairing species have different chemical potentials, imposed in our case, with different number densities, leading to a finite 'polarization'. This is of much experimental and theoretical ...

Finally, we have calculated the Deybe-Waller factor in solid helium for a range of temperatures and densities, and compared the scaling behavior with the predictions of harmonic theory. The first non-Gaussian contribution ...

Based on Richard P. Feynman's formulation of quantum mechanics, Path Integral Monte Carlo is a computational ab-initio method to calculate finite temperature equilibrium properties of quantum many-body systems. As input, ...

We study two representative problems related to the dynamics of pattern formation in non-linear, dissipative systems far from equilibrium. The first problem addresses the dynamical mechanism of velocity and shape selection ...

The quaternary material aluminum gallium indium prosphide (($\rm Al\sb{x}Ga\sb{1-x})\sb{y}In\sb{1-y}P$) is used in the fabrication of visible lasers and light emitting diodes. There are problems in this material related ...

In the experimental part, we investigate the microstructures resulting under ion-beam mixing in Ag-Cu multilayers. We find that, regardless of the irradiation temperature, extensive grain growth takes place. In the regime ...

Finally, Chapter 5 treats the phase behavior of both additive and non-additive binary hard disk fluid mixtures, for very large size asymmetries. Using a systematic extrapolation in the non-additivity parameter I have been ...

Charge ordering (CO) phase transformations in La1-xCa xMnO3 were studied at Ca doping levels x = 0.33, 0.50, 0.67, 0.75 and 0.77. Temperature-controlled in-situ electron diffraction and high resolution dark field images ...

In Part I of this thesis, we present experimental evidence demonstrating that a metal-insulator (M-I) phase transition can occur separately from the liquid-gas (L-G) transition in the exciton/electron-hole (e-h) gas/e-h ...
