    • A (0,2) mirror duality 

      Bertolini, Marco; Plesser, M Ronen
      We construct a class of exactly solved (0,2) heterotic compactifications, similar to the (2,2) models constructed by Gepner. We identify these as special points in moduli spaces containing geometric limits described ...
    • A nontrivial critical fixed point for replica-symmetry-breaking transitions 

      Charbonneau, Patrick; Yaida, Sho (2017-04-01)
      The transformation of the free-energy landscape from smooth to hierarchical is one of the richest features of mean-field disordered systems. A well-studied example is the de Almeida-Thouless transition for spin glasses in ...
    • Coarse-graining quivers 

      Narayan, K; Plesser, M Ronen
      We describe a block-spin-like transformation on a simplified subset of the space of supersymmetric quiver gauge theories that arise on the worldvolumes of D-brane probes of orbifold geometries, by sequentially Higgsing the ...
    • Counting Yang-Mills Dyons with Index Theorems 

      Stern, M; Yi, P (Phys.Rev. D, 2017-06-01)
      We count the supersymmetric bound states of many distinct BPS monopoles in N=4 Yang-Mills theories and in pure N=2 Yang-Mills theories. The novelty here is that we work in generic Coulombic vacua where more than one adjoint ...
    • From vortices to instantons on the Euclidean Schwarzschild manifold 

      Nagy, Ákos; Oliveira, Gonçalo (2018-01-18)
      The first irreducible solution of the $\SU (2)$ self-duality equations on the Euclidean Schwarzschild (ES) manifold was found by Charap and Duff in 1977, only 2 years later than the famous BPST instantons on $\rl^4$ were ...
    • Higher genus knot contact homology and recursion for colored HOMFLY-PT polynomials 

      Ekholm, Tobias; Ng, Lenhard
      We sketch a construction of Legendrian Symplectic Field Theory (SFT) for conormal tori of knots and links. Using large $N$ duality and Witten's connection between open Gromov-Witten invariants and Chern-Simons gauge theory, we ...
    • Instantons on multi-Taub-NUT Spaces I: Asymptotic Form and Index Theorem 

      Cherkis, Sergey A; Larrain-Hubach, Andres; Stern, Mark (Journal of Differential Geometry, 2019-12-06)
      We study finite action anti-self-dual Yang-Mills connections on the multi-Taub-NUT space. We establish the curvature and the harmonic spinors decay rates and compute the index of the associated Dirac operator. This is ...
    • Instantons on multi-Taub-NUT Spaces II: Bow Construction 

      Cherkis, Sergey; Larraín-Hubach, Andrés; Stern, Mark
      Unitary anti-self-dual connections on Asymptotically Locally Flat (ALF) hyperk\"ahler spaces are constructed in terms of data organized in a bow. Bows generalize quivers, and the relevant bow gives rise to the underlying ...
    • Invariance Theorems for Supersymmetric Yang-Mills Theories 

      Sethi, S; Stern, M (Adv.Theor.Math.Phys., 2017-06-01)
      We consider quantum mechanical Yang-Mills theories with eight supercharges and a $Spin(5) \times SU(2)_R$ flavor symmetry. We show that all normalizable ground states in these gauge theories are invariant under this flavor ...
    • Mirror Symmetry and Discriminants 

      Aspinwall, Paul S; Plesser, M Ronen; Wang, Kangkang
      We analyze the locus, together with multiplicities, of "bad" conformal field theories in the compactified moduli space of N=(2,2) superconformal field theories in the context of the generalization of the Batyrev ...
    • New G<inf>2</inf>-holonomy cones and exotic nearly Kahler structures on S6 and S3 x S3 

      Foscolo, L; Haskins, M (Annals of Mathematics, 2017-01-01)
      © 2017 Department of Mathematics, Princeton University. There is a rich theory of so-called (strict) nearly Kahler manifolds, almost-Hermitian manifolds generalising the famous almost complex structure on the 6-sphere induced ...
