Density functional explorations of quadrupole coupling constants for BN, BP, AlN, and AlP graphene–like structures
Stabilizations and atomic level quadrupole coupling constant (CQ) properties have been investigated for graphene–like monolayers (G–monolayers) of boron nitride (BN), boron phosphide (BP), aluminum nitride (AlN), and aluminum phosphide (AlP) structures. To this aim, density functional theory (DFT) calculations have been performed to optimize the model structures and also to evaluate the CQ para...

متن کاملChaotic Coupling Constants
We examine some novel physical consequences of the general structure of moduli spaces of string vacua. These include (1) finiteness of the volume of the moduli space and (2) chaotic motion of the moduli in the early universe. To fix ideas we examine in detail the example of the (conjectural) dilaton-axion “S-duality” of four-dimensional string compactifications. The facts (1) and (2) together m...
متن کاملHyperfine Coupling Constants
The IH hyperfine coupling constants of free radicals and ions have been successfully studied by our newly modified s-p· separation type INDO-MO method->, and the most of our calculated coupling constants are significantly better than the corresponding results of the conventional INDO-MO method."" The nuclear hyperfine coupling constant is assumed to be directly proportional to the 2s spin densi...
متن کاملDynamical Gauge Coupling Constants
In string theory the coupling parameters are functions of moduli fields. The actual values of the coupling constants are then dynamically determined through the vacuum expextation values of these fields. We review the attempts to connect such theories to low energy effective field theories with realistic gauge coupling constants. This includes a discussion of supersymmetry breakdown, the questi...
