Analysis of the compressibility of a finite symmetrical nucleus in terms of a simple, analytically tractable model

Journal Article Maheswari, V S.U. ; Ramamurthy, V S ; Satpathy, L - Physical Review, C (Nuclear Physics); (United States)

The liquid-drop model type expansion of the finite nuclear compressibility coefficients {ital K}{sub {ital A}} is studied in an energy density formalism, using a leptodermous expansion of the energies. It is found that the effective curvature compressibility coefficient {ital K}{sub {ital c}} is always negative for Skyrme type forces. It is also shown that the unexpectedly large value of about {minus}800 MeV of the surface compressibility coefficient {ital K}{sub {ital s}} found by Sharma {ital et} {ital al}. is an artifact of their analysis procedure.

Bad Metallic Transport in a Modified Hubbard Model

Journal Article Mousatov, Connie H. ; Esterlis, Ilya ; Hartnoll, Sean A. - Physical Review Letters

Strongly correlated metals often display anomalous transport, including T-linear resistivity above the Mott-Ioffe-Regel limit. We introduce a tractable microscopic model for bad metals, by restoring in the well-known Hubbard model—with hopping t and on-site repulsion U—a “screened Coulomb” interaction between charge densities that decays exponentially with spatial separation. This interaction lifts the extensive degeneracy in the spectrum of the t = 0 Hubbard model, allowing us to fully characterize the small t electric, thermal, and thermoelectric transport in our strongly correlated model. Throughout the phase diagram we observe T-linear resistivity above the Mott-Ioffe-Regel limit, together with strong violation of themore »« less

Interplay between parity-time symmetry, supersymmetry, and nonlinearity: An analytically tractable case example

Journal Article Kevrekidis, Panayotis G. ; Cuevas–Maraver, Jesús ; Saxena, Avadh ; ... - Physical Review. E, Statistical, Nonlinear, and Soft Matter Physics

In the present work, we combine the notion of parity-time (PT) symmetry with that of supersymmetry (SUSY) for a prototypical case example with a complex potential that is related by SUSY to the so-called Pöschl-Teller potential which is real. Not only are we able to identify and numerically confirm the eigenvalues of the relevant problem, but we also show that the corresponding nonlinear problem, in the presence of an arbitrary power-law nonlinearity, has an exact bright soliton solution that can be analytically identified and has intriguing stability properties, such as an oscillatory instability, which is absent for the corresponding solutionmore »« less

TRACTABLE POTENTIAL FUNCTIONS AS DERIVED FROM THEORIES OF BONDING FOR METAL CARBONYLS AND METAL CYANIDE COMPLEXES

Technical Report Jones, L H

Various potential functions used ior normal coordinate analyses of molecular vibrations are discussed. In a general quadratic potential function there are too many force constants to determine from the obserwed frequencies. Therefore, a pi-electron interaction valence force field is derived for the octahedral metal hexacarbonyls. The results of application of this treatment to Mo(CO)/sub 6/ are given and shown to be quite satisfactory. The Urey-Bradley Field, which gives satisfactory results for some molecules is shown to be inferior for metal carbonyls. A brief discussion of the modification of this pi IVFF for metal-cyanide complexes is presented. (auth)
