One-dimensional hydrogen atom
… structures. These resonant structures are nearly one-dimensional and whose electronic distributions are highly extended along the field, and which may have enormous electric dipole moments. Such one-dimensional hydrogen atoms are ideal tools for studying a number of physical phenomena and …

One-Dimensional Fractal Wave Equations
We study one-dimensional wave equations defined by a class of fractal Laplacians. These Laplacians are defined by fractal measures generated by iterated function systems with overlaps, such as the well-known infinite Bernoulli convolution associated with golden ratio and the 3-fold convolution of …

One dimensional pollutant transport model
… the development of a numerical model for one-dimensional pollutant transport in a porous medium. A computer program POLUTE1D has been developed. The numerical model is based on the flow and mass transport equations and the finite element method has been used for its formulation. The …

Quasi-One-Dimensional Ultracold Fermi Gases
… Using phase separation as a guide, we probe the dimensional crossover between 1D and 3D. The phase separation in 1D is inverted from that in 3D, which provides a unique characteristic to distinguish between the dimensions. By varying the tunneling between tubes and the atomic interactions in a 2D …

Transport imaging in the one dimensional limit
… modeling and initial characterization. One dimensional structures are being integrated into forefront electronics due to their inherent advantages in size, packing density and power consumption. In this work the one dimensional equation for steady state minority carrier recombination …

One-dimensional bosonization approach to higher dimensions
… to theoretical studies of strongly interacting one-dimensional and quasi one-dimensional electron systems. The properties of one-dimensional electron systems can be studied within the bosonization technique, which presents fermions as collective bosonic density excitations. The power of this …

Aquatic toxicity of one dimensional carbon nanomaterials
This study determined the toxicity of one dimensional carbon nanomaterials (CNMs) to amphipods, midge, oligochaetes and juvenile mussels in water and sediment. As-produced or modified carbon nanotubes (CNTs) and silicon carbide nanowires (SiCNW) were selected to represent CNMs. Sediment tests were …

Studies of Integrable One-Dimensional Quantum Systems
… I use the Bethe Ansatz (BA) to study various one-dimensional models. I first go through some background on the BA (both the coordinate and algebraic forms). I start the study by using the BA to compare bound state occurrences between the 2-particle XXZ, Bose–Hubbard, and Fermi– Hubbard models. …

One-Dimensional Radial Flow Turbomachinery Performance Modeling
The Two-Element In Series (TEIS) and Two-Zone models have been used successfully for over twenty years to model test data for radial flow compressors and pumps. The models can also be used to predict the performance of new machines provided that the model inputs can be accurately specified. …

Correlation in the One Dimensional Electron Gas
Our calculations are quantitatively exact which allows us to compare with recent experiments [Steinberg et al., Phys. Rev. B 77, 113307 (2006)], by introducing an accurate model for the screening in the experiment and explicitly including the finite length of the sample in our simulations. We find …

Computation of the one-dimensional unwrapped phase
… the discrete-time Fourier transform (DTFT) of a one-dimensional finite-length signal is explored. The phase of the DTFT is not unique, and may contain integer multiple of 27r discontinuities. The unwrapped phase is the instance of the phase function chosen to ensure continuity. This thesis …

Correlations in the one-dimensional Hubbard model
Correlation effects in the one-dimensional Hubbard model are studied by application of the L-resolvent method. The calculations are well beyond one-particle mean field approximation. All correlations involving two neighboring sites are included exactly and higher order correlations are …
