Strongly orthotropic continuum mechanics
… contribution of this dissertation is a theory of Strongly Orthotropic Continuum Mechanics that is derived entirely from an assertion of geometric strain indeterminacy. Implementable into the finite element method, it can resolve widespread kinematic misrepresentations and offer unique and …

Compactons in strongly nonlinear lattices
In the present work, we study wave phenomena in strongly nonlinear lattices. Such lattices are characterized by the absence of classical linear waves. We demonstrate that compactons – strongly localized solitary waves with tails decaying faster than exponential – exist and that they play a major …

(Strongly) zero-dimensional ordered spaces
… 1988] and [Brummer 1977, 1982]. We also study strongly zero-dimensional ordered topological spaces and their relation with functorial quasi-uniformities. In this respect, our results are influenced by those of [Fora 1984], [Banaschewski and Brummer 1990] and [Kiinzi 1990] for strongly …

Holography and strongly correlated systems
… or holography - to problems associated with strongly coupled quantum field theories under extreme conditions such as finite temperature or density. We first study a strongly coupled field theory at finite temperature. We demonstrate that its low frequency limit is determined by the horizon …

Probes of strongly interacting plasma
… results on the medium/probe interaction in the strongly coupled plasma produced in heavy-ion collisions. Such processes involve physics at multiple energy scales making a consistent theoretical description challenging. We show how insights from various regimes can be combined to extend our …

Strongly coupled fermions on the lattice
… of phase transitions in a variety of other strongly coupled theories of interest to both high energy and condensed matter theorists. The lattice approach to QCD has led to an understanding of quark confinement, chiral symmetry breaking and hadronic physics. Correlation functions of hadronic …

Delocalization phenomena in strongly disordered systems
… we study delocalization mechanisms in strongly disordered systems. We focus on one-dimensional systems where the localizing effects of disorder are strongest. Our explorations of delocalization mechanisms will reveal new insights into the nature of Anderson transitions in the context of …

Microscopic Simulations of Strongly Paired Fermions
Results for the aforementioned observables are also given for the case of low-density neutron matter, which is characterized by a finite effective range and a more complicated interaction. These results are also compared with our cold-atom predictions and also with other many-body approaches to …

Magnetism in strongly correlated electron systems
… two very different examples of magnetism in strongly correlated electron systems, the high-T$\sb{c}$ materials and heavy fermions.

Power transfer through strongly coupled resonances
Using self-resonant coils in a strongly coupled regime, we experimentally demonstrate efficient non-radiative power transfer over distances of up to eight times the radius of the coils. We use this system to transfer 60W with approximately 45% efficiency over distances in excess of two meters. We …

SPIN-ORBIT COUPLING IN STRONGLY CORRELATED SYSTEMS
… it is proposed that spin-orbit coupling can be strongly enhanced by Coulomb interaction in 5f metals. Modest values of the Coulomb interaction can induce up to a four-fold enhancement. In the third case, a model is presented to characterize spin-orbit enhancement in a strongly correlated …

Statistical mechanics of strongly driven Ising systems
This work considers the behavior of the Ising model of a ferromagnet subject to a strong, randomly switching external driving field. A formalism based on the master equation to handle such nonequilibrium systems is introduced and applied to a mean field approximation, and one- and two-dimensional …

Spectral properties of strongly correlated electron systems
… O 2p_{\sigma} and Cu 3d_{x^2-y^2} orbitals are strongly peaked along the CuO_2 plane, i.e. most photoelectrons are emitted at grazing angles. This suggests that surface states play an important role in the observed ARPES spectra, consistent with recent data from Sr_2CuCl_2O_2. We show that a …

Frustrated Magnetism in Strongly Correlated Electron Systems
… and their 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 …

Variational study of strongly correlated electronic models
… interest 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 …
