Topology Change from (Heterotic) Narain T-Duality
Jarah Evslin, Ruben Minasian
We consider Narain T-duality on a nontrivially fibered n-torus bundle in the presence of a topologically nontrivial NS H flux. The action of the duality group on the topology and H…
Contrasting confinement in superQCD and superconductors
Jarah Evslin
The vacuum of supersymmetric gauge theories (SQCD) with N=2 softly broken to N=1 resembles that of a BCS superconductor in that it has a condensate which collimates flux into vorti…
Which BPS Baryons Minimize Volume?
Jarah Evslin, Stanislav Kuperstein
A BPS 3-cycle in a Sasaki-Einstein 5-manifold in general does not minimize volume in its homology class, as we illustrate with several examples of non-minimal volume BPS cycles on…
Geometric Engineering 5d Black Holes with Rod Diagrams
Jarah Evslin
Static solutions of 5-dimensional gravity with two spatial Killing vectors are characterized by their rod structures. In this note we describe how the orbifold singularities and th…
Topological strings live on attractive manifolds
Jarah Evslin, Ruben Minasian
We add to the mounting evidence that the topological B model's normalized holomorphic three-form has integral periods by demonstrating that otherwise the B2-brane partition functio…
Trivializing a Family of Sasaki-Einstein Spaces
Jarah Evslin, Stanislav Kuperstein
We construct an explicit diffeomorphism between the Sasaki-Einstein spaces Y^{p,q} and the product space S^3 \times S^2 in the cases q \le 2. When q=1 we express the Kähler quotien…
