A (0,2) mirror duality
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 replicasymmetrybreaking transitions
(20170401)The transformation of the freeenergy landscape from smooth to hierarchical is one of the richest features of meanfield disordered systems. A wellstudied example is the de AlmeidaThouless transition for spin glasses in ... 
Coarsegraining quivers
We describe a blockspinlike transformation on a simplified subset of the space of supersymmetric quiver gauge theories that arise on the worldvolumes of Dbrane probes of orbifold geometries, by sequentially Higgsing the ... 
Counting YangMills Dyons with Index Theorems
(Phys.Rev. D, 20170601)We count the supersymmetric bound states of many distinct BPS monopoles in N=4 YangMills theories and in pure N=2 YangMills 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
(20180118)The first irreducible solution of the $\SU (2)$ selfduality 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 HOMFLYPT polynomials
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 GromovWitten invariants and ChernSimons gauge theory, we ... 
Instantons on multiTaubNUT Spaces I: Asymptotic Form and Index Theorem
(Journal of Differential Geometry, 20191206)We study finite action antiselfdual YangMills connections on the multiTaubNUT space. We establish the curvature and the harmonic spinors decay rates and compute the index of the associated Dirac operator. This is ... 
Instantons on multiTaubNUT Spaces II: Bow Construction
Unitary antiselfdual 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 YangMills Theories
(Adv.Theor.Math.Phys., 20170601)We consider quantum mechanical YangMills 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
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 S^{6} and S^{3} x S^{3}
(Annals of Mathematics, 20170101)© 2017 Department of Mathematics, Princeton University. There is a rich theory of socalled (strict) nearly Kahler manifolds, almostHermitian manifolds generalising the famous almost complex structure on the 6sphere induced ...
