“…The LCAO-based energy bands and DOS have been plotted using DL Visualize software [37]. Except for some fine structures and bandgaps, the overall Original Paper shape of our energy bands is in agreement with the reported data [7][8][9][11][12][13]. Here, we interpret the energy bands (with energy scale as E -E F ) deduced from the FP-LAPW approach in the energy range -6.0 eV to 12.0 eV as shown in Fig.…”

“…Using ab-initio HF pseudopotential linear combination of atomic orbitals (LCAO), Apra et al [6] have reported the electronic structure of AgCl. Regarding computation of electronic structure using full-potential augmented planewave (FP-LAPW) method, Boer and de Groot [7] have used WIEN95 code incorporating the local density approximation (LDA). Okoye [8] has used FP-LAPW with the generalized gradient approximation (GGA) of PerdewBurke-Ernzerhof (PBE) to investigate the pressure dependence of bandgaps in silver halides.…”

We report the band‐structure calculations and the first ever electron momentum densities of AgCl and AgBr. Isotropic Compton profiles of these compounds are measured at an intermediate resolution using a 20 Ci 137Cs Compton spectrometer. We have computed Compton profiles, energy bands, density of states and charge density using Hartree–Fock and density‐functional theories. It is seen that the Hartree–Fock theory‐based Compton line shapes are in a better agreement with the measurements. In addition, we have also derived the energy bands and density of states using the full‐potential linearized augmented plane‐wave method. The Compton data is also analyzed at the equal‐valence‐electron‐density scale. The present data shows that AgBr is more covalent than AgCl, which is in agreement with the present Mulliken's population analysis, valence charge densities and other available ionicity trends.

“…III D, which describe the ''core'' region of the asymptotically flat solitons, we can use the powerful AdS/CFT correspondence machinery to identify the corresponding states in the CFT. The dual CFT for the asymptoticallyAdS 3 S 3 T 4 spaces with radius ' Q 1 Q 5 1=4 is a sigma model with target space a deformation of the orbifold T 4 N =S N [41][42][43], where…”

We construct smooth nonsupersymmetric soliton solutions with D1-brane, D5-brane, and momentum charges in type IIB supergravity compactified on T 4 S 1 , with the charges along the compact directions. This generalizes previous studies of smooth supersymmetric solutions. The solutions are obtained by considering a known family of U1 U1 invariant metrics, and studying the conditions imposed by requiring smoothness. We discuss the relation of our solutions to states in the CFT describing the D1-D5 system and describe various interesting features of the geometry.

“…These operators are expected to be dual to multi-particle states in the dual string theory. In the case of AdS 3 × S 3 × M 4 it was found in [12] that multiparticle states in supergravity were needed to account for the elliptic genus computed from the dual CFT.…”

Giant gravitons, Bogomol’nyi-Prasad-Sommerfield bounds, and noncommutativity

2001

It has been recently suggested that gravitons moving in AdS m × S n spacetimes along the S n blow up into spherical (n−2) branes whose radius increases with increasing angular momentum. This leads to an upper bound on the angular momentum, thus "explaining" the stringy exclusion principle. We show that this bound is present only for states which saturate a BPS-like condition involving the energy E and angular momentum J, E ≥ J/R, where R is the radius of S n . Restriction of motion to such states lead to a noncommutativity of the coordinates on S n . As an example of motions which do not obey the exclusion principle bound, we show that there are finite action instanton configurations interpolating between two possible BPS states. We suggest that this is consistent with the proposal that there is an effective description in terms of supergravity defined on noncommutative spaces and noncommutativity arises here because of imposing supersymmetry.
