The holographic supersymmetric Renyi entropy in five dimensions

We compute the supersymmetric Renyi entropy across an entangling three-sphere for five-dimensional superconformal field theories using localization. For a class of USp(2N) gauge theories we construct a holographic dual 1/2 BPS black hole solution of Euclidean Romans F(4) supergravity. The large N limit of the gauge theory results agree perfectly with the supergravity computations.Comment: 19 page

Localization on Three-Manifolds

We consider supersymmetric gauge theories on Riemannian three-manifolds with the topology of a three-sphere. The three-manifold is always equipped with an almost contact structure and an associated Reeb vector field. We show that the partition function depends only on this vector field, giving an explicit expression in terms of the double sine function. In the large N limit our formula agrees with a recently discovered two-parameter family of dual supergravity solutions. We also explain how our results may be applied to prove vortex-antivortex factorization. Finally, we comment on the extension of our results to three-manifolds with non-trivial fundamental group.Comment: 34 pages; v2: discussion of vortex factorization added; v3: minor correction

The Pub, the People, the Place, the Passions, and the Principles: The Social and Personal Context of Engagement in a Collective Action

Towards the end of 2006 the owners of a small, historic public house withdrew from sale the locally produced beer that had been sold there for many years. Pub regulars instigated a boycott in an attempt to have the beer reinstated. Following a four-month widely supported boycott and considerable media coverage, the pub company owners returned the local beer to the pub. This paper reports on a selection of the experiences of some of those taking an active role in the boycott. Following intensive semi-structured interviews, we extracted a number of themes from participants’ accounts. We identify potentially important factors in the “causal net,” explaining their involvement in the boycott. Affective experience, collective interests, and deontological considerations [the obligation to do the right thing even if doing so could be personally damaging] emerge as important dimensions of people’s discussion of their participation. The findings are discussed in relation to theoretical perspectives bearing on an understanding of action choices
