Sudden approximation applied to computation of rotational transition probability and inelastic total cross sections for scattering of polar and nonpolar diatomic molecules by atom

Composition is not research

Copyright © Cambridge University Press 2015Composers in academic institutions are increasingly required to describe their activities in terms of 'research ' - formulating 'research questions', 'research narratives', 'aims' and 'outcomes'. Research plans and funding applications require one to specify the nature of the original contribution that will be made by a piece of music, even before it is composed. These requirements lead to an emphasis on collaborative work, technology and superficial novelty of format. Yet the very idea that musical composition is a form of research is a category error: music is a domain of thought whose cognitive dimension lies in embodiment, revelation or presentation, but not in investigation and description. It is argued here that the idea of composition as research is not only objectively false but inimical to genuine musical originality

Dual vortices in Abelian projected SU(2) in the Polyakov gauge

We study dual Abrikosov vortices in Abelian projected SU(2) gauge theory in the Polyakov gauge. We show that vortices are present in this gauge but they are suppressed with respect to the maximal Abelian gauge. We interpret this difference in terms of the shielding of the electric charge by the charged coset fields.Comment: Talk presented at LATTICE96(topology), 3 pages, latex, 4 eps figures, uses epsfig and espcrc2.sty (included
