On the Cohomology of the Noncritical -string
E. Bergshoeff, J. de Boer, M. de Roo +1
We investigate the cohomology structure of a general noncritical -string. We do this by introducing a new basis in the Hilbert space in which the BRST operator splits into a `…
Twistor-like Formulation of Super p-Branes
E. Bergshoeff, E. Sezgin
Closed super (p+2)-forms in target superspace are relevant for the construction of the usual super p-brane actions. Here we construct closed super (p+1)-forms on a {\it worldvolume…
Gravitational Lenses and Unconventional Gravity Theories
Jacob D. Bekenstein, Robert H. Sanders
We study gravitational lensing by clusters of galaxies in the context of the generic class of unconventional gravity theories of the scalar--tensor type. For positive energy scalar…
Colors and color gradients in bulges of galaxies
M. Balcells, R. F. Peletier
We have obtained surface photometry in U, B, R and I for a complete optically selected sample of 45 early-type spiral galaxies, to investigate the colors and color gradients of spi…
Polaronic Self-Localization Effects in the Three Band Peierls Hubbard Model
A. Dobry, A. Greco, J. Lorenzana +1
We have studied the three-band Peierls-Hubbard model describing the Cu-O layers in high-T superconductors by using Lanczos diagonalization and assuming infinite mass for the io…
Nucleon polarization in three-body models of polarized \bbox{^6}Li
N. W. Schellingerhout, L. P. Kok, S. A. Coon +1
Just as $^3\roarrow{\rm He}$ can be approximately characterized as a polarized neutron target, polarized \Li6D has been advocated as a good {\em isoscalar} nuclear target for the e…
