The effects of the residual proton-neutron interactions on bandcrossing features are studied by means of shell model calculations for nucleons in a high-j intruder orbital. The presence of an odd-nucleon shifts the frequency of the alignment of two nucleons of the other kind along the axis of rotation. It is shown that the anomalous delayed crossing observed in nuclei with aligning neutrons and...

For each real number Λ a Lie algebra of nonlinear vector fields on three dimensional Euclidean space is reported. Although each algebra is mathematically isomorphic to gl(3, R), only the Λ = 0 vector fields correspond to the usual generators of the general linear group. The Λ < 0 vector fields integrate to a nonstandard action of the general linear group; the Λ > 0 case integrates to a local Li...

Tony Thomas presented us with a challenge in setting up this workshop—to make the connection between quark and hadronic degrees of freedom. I have accepted this challenge and will go even further by attempting to make contact between the physics of Tony Thomas and that of Ulf Meissner! My point of contact will be the study of low energy baryon phyics, studied a number of years ago by Tony and h...

We derive an effective local operator produced by certain wormhole instantons in a theory containing a massless Wess-Zumino multiplet coupled to N=1 su-pergravity. The induced interactions are D terms, and hence will not lead to spontaneous supersymmetry breaking. We conclude that supersymmetry suppresses wormhole-induced matter couplings.
