Electronic-structure-induced deformations of liquid metal clusters

Electronic-structure-induced deformations of liquid metal clusters.

Ab initio molecular dynamics is used to study deformations of sodium clusters at temperatures 500 · · · 1100 K. Open-shell Na14 cluster has two shape isomers, prolate and oblate, in the liquid state. The deformation is stabilized by opening a gap at the Fermi level. The closed-shell Na8 remains magic also at the liquid state. Typeset using REVTEX

Calculated electronic profiles for liquid-metal surfaces.

Complex structure-induced deformations of σ-models

We describe a deformation of the principal chiral model (with an evendimensional target space G) by a B-field proportional to the Kähler form on the target space. The equations of motion of the deformed model admit a zero-curvature representation. As a simplest example, we consider the case of G = S × S. We also apply a variant of the construction to a deformation of the AdS3 × S × S (super-)σ-...

Electronic structure of indium phosphide clusters: anion

Ž . Photoelectron spectra for indium phosphide InP cluster anions comprised of up to 27 atoms were measured at a photodetachment wavelength of 266 nm. Results are presented for cluster anions of both stoichiometric and non-stoichiometŽ y y . Ž . ric composition In P , In P ; xs1–13 .
