Zero-point vibrational energies of spherical Coulomb crystals.
Thanks to their well-pronounced shell structures, spherical Coulomb crystals possess zero-point vibrational energies {epsilon(SCC)(N)} that are dominated by one component. This shell-additive contribution, which arises from particle motions within individual shells, is readily modeled with a superposition of modified Thomson problems with no adjustable parameters. On the other hand, the negativ...
متن کاملCOMPUTATIONAL ENUMERATION OF POINT DEFECT CLUSTERS IN DOUBLE- LATTICE CRYSTALS
The cluster representation matrices have already been successfully used to enumerate close-packed vacancy clusters in all single-lattice crystals [I, 2]. Point defect clusters in double-lattice crystals may have identical geometry but are distinct due to unique atomic postions enclosing them. The method of representation matrices is extended to make it applicable to represent and enumerate ...
متن کاملNegative Refraction Angular Characterization in One-Dimensional Photonic Crystals
BACKGROUND Photonic crystals are artificial structures that have periodic dielectric components with different refractive indices. Under certain conditions, they abnormally refract the light, a phenomenon called negative refraction. Here we experimentally characterize negative refraction in a one dimensional photonic crystal structure; near the low frequency edge of the fourth photonic bandgap....
متن کاملComparison of One-point and Two-point Methods for Estimation of Infiltration Parameters in Furrow Irrigation
Infiltration is one of the most important hydraulic parameters affecting surface irrigation and one ofthe most difficult parameters in practical field determinations. The infiltration equations are used todescribe water flow hydraulics and surface irrigation systems design. But determination of theparameters in these equations are costly and time consuming. Therefore, some estimating methods ar...
متن کاملPhase Properties of One-Dimensional Quaternary Photonic Crystals
In this paper, properties of reflection phase in one-dimensional quaternary photonic crystals combining dispersive meta-materials and positive index materials are investigated by transfer matrix method. Two omnidirectional band gaps are located in the band structure of considered structure. However, we limit our studies to the frequency range of the second wide band gap. We observe that the val...
