Granular Gases

"Granular Gases" are diluted many-particle platforms within which the suggest loose course of the debris is way higher than the common particle dimension, and the place particle collisions ensue dissipatively. The dissipation of kinetic strength may end up in results akin to the formation of clusters, anomalous diffusion and attribute surprise waves to call yet a couple of.

Highlights regimen supernova polarimetry and new insights into center cave in and thermonuclear explosions.

Molecular Magnets: Physics and Applications

This publication presents an summary of the actual phenomena chanced on in magnetic molecular fabrics over the past twenty years. it really is written by way of major scientists having made crucial contributions to this lively zone of study. the most themes of this e-book are the foundations of quantum tunneling and quantum coherence of single-molecule magnets (SMMs), phenomena which transcend the physics of person molecules, similar to the collective habit of arrays of SMMs, the physics of one-dimensional single–chain magnets and magnetism of SMMs grafted on substrates.

This is the minimum number of terms that can reveal the essential structure of a CC treatment of properties. , for the polarizability tensor α), as illustrated later in this section. In the CC theory,2,30,31 the exact wavefunction jΨ iCC of a system is À Á jΨ iCC ¼ exp + T^ jΦ0 i, where jΦ0i is an HF reference wavefunction and T^ is the excitation (cluster) operator. T^ is expressed as T^ ¼ T^ 1 + T^ 2 + ⋯ + T^ n ⋯, where T^ 1 , T^ 2 , …T^ n are single-, double-, … where ^ ðλÞ , λH i¼1 i i XNλ Nμ X ^ ðμÞ , μH i¼1 i i and 39 Parallel Linear-Response Coupled-Cluster-Theory Module n-excitation operators from jΦ0i.

10) and (12), can be evaluated with the CC diagrammatic techniques discussed in Refs. 78,79. , the μi Þ previously discussed ΔDpq, ΔΓ pqsr, ΔDðpqμi Þ , and ΔΓ ðpqsr ) and an 44 Ajith Perera and Jorge A. Morales MO-response density matrix term,75,80 which is calculated by solving a CPHF-type equation. As discussed in Section 1, this latter part is not included in the response treatment of the polarizabilities reported and discussed in Section 3. 44 Various types of first-order and second-order properties can be calculated with the CC response treatment expounded above.

Computational Details, Results, and Discussion 4. , 201346), we present a new massively parallel linear-response CC module to calculate up to second-order properties. This module benefits from the parallel-computing environment in the ACES III program, which includes the super instruction processor and the super instruction architecture language. This implementation is based on a CC response treatment of properties that is discussed in detail. While this module is applicable to any of the aforesaid properties, we illustrate its use through the calculation of the second-order static dipole polarizability tensors and their related average polarizabilities and polarizability anisotropies of large molecules.
