Phases of flux vacua and their quantum symmetries
Dan Israel, Ilarion V. Melnikov, Yann Proto
We present a torsional linear sigma model with (0,2) supersymmetry that realizes, in its large radius phase, a five-dimensional heterotic flux vacuum, and we use the linear sigma m…
Topology change and heterotic flux vacua
Dan Israel, Ilarion V. Melnikov, Ruben Minasian +1
We investigate the interrelation between topology and Narain T-duality of heterotic flux vacua. We present evidence that all 5 and 4-dimensional Minkowski space heterotic flux back…
A Worldsheet Approach to Heterotic Flux Backgrounds
Dan Israel, Yann Proto
Heterotic backgrounds with torsion preserving minimal supersymmetry in four dimensions can be obtained as orbifolds of principal bundles over . We consider a worldsheet…
Moduli spaces of non-geometric type II/heterotic dual pairs
Yoan Gautier, Dan Israel
We study the moduli spaces of heterotic/type II dual pairs in four dimensions with N=2 supersymmetry corresponding to non-geometric Calabi-Yau backgrounds on the type II side and t…
Heterotic Hyper-Kahler Flux Backgrounds
Nick Halmagyi, Dan Israel, Matthieu Sarkis +1
We study Heterotic supergravity on Hyper-Kahler manifolds in the presence of non-trivial warping and three form flux with Abelian bundles in the large charge limit. We find exact,…
Threshold corrections in heterotic flux compactifications
Carlo Angelantonj, Dan Israel, Matthieu Sarkis
We compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of N=2 non-Kähler heterotic compactifications with three-form flux, consist…
Dressed elliptic genus of heterotic compactifications with torsion and general bundles
Dan Israel, Matthieu Sarkis
We define and compute the dressed elliptic genus of N = 2 heterotic compactifications with torsion that are principal two-torus bundles over a K3 surface. We consider the most gene…
The Abelian Heterotic Conifold
Nick Halmagyi, Dan Israel, Eirik Eik Svanes
We study heterotic supergravity on the conifold and its Z2 orbifold with Abelian gauge fields and three-form flux. At large distances, these solutions are locally Ricci-flat, have…
New supersymmetric index of heterotic compactifications with torsion
Dan Israel, Matthieu Sarkis
We compute the new supersymmetric index of a large class of N=2 heterotic compactifications with torsion, corresponding to principal two-torus bundles over warped K3 surfaces with…
Asymmetric Gepner models in type II
Dan Israel, Vincent Thiery
We describe new four-dimensional type II compactifications with N=2 supersymmetry, based on asymmetric Gepner models for K3 x T^2. In more than half of these models, all the K3 mod…
T-Duality in Gauged Linear Sigma-Models with Torsion
Dan Israel
(0,2) gauged linear sigma models with torsion, corresponding to principal torus bundles over warped CY bases, provide a useful framework for getting exact statements about perturba…
Gauge Threshold Corrections for N = 2 Heterotic Local Models with Flux, and Mock Modular Forms
Luca Carlevaro, Dan Israel
We determine threshold corrections to the gauge couplings in local models of N=2 smooth heterotic compactifications with torsion, given by the direct product of a warped Eguchi-Han…
Rolling tachyons for separated brane-antibrane systems
Dan Israel, Flavien Kiefer
We consider tachyon condensation between a D-brane and an anti-D-brane in superstring theory, when they are separated in their common transverse directions. A simple rolling tachyo…
String Theory on Warped AdS_3 and Virasoro Resonances
Stéphane Detournay, Dan Israel, Joshua M. Lapan +1
We investigate aspects of holographic duals to time-like warped AdS_3 space-times--which include Gödel's universe--in string theory. Using worldsheet techniques similar to those th…
Brane Dynamics and 3D Seiberg Duality on the Domain Walls of 4D N=1 SYM
Adi Armoni, Amit Giveon, Dan Israel +1
We study a three-dimensional U(k) Yang-Mills Chern-Simons theory with adjoint matter preserving two supersymmetries. According to Acharya and Vafa, this theory describes the low-en…
Double-Scaling Limit of Heterotic Bundles and Dynamical Deformation in CFT
Luca Carlevaro, Dan Israel, Marios Petropoulos
We consider heterotic string theory on Eguchi-Hanson space, as a local model of a resolved A_1 singularity in a six-dimensional flux compactification, with an Abelian gauge bundle…
D-branes at multicritical points
Matthias R. Gaberdiel, Dan Israel, Eliezer Rabinovici
The moduli space of c=1 conformal field theories in two dimensions has a multicritical point, where a circle theory is equivalent to an orbifold theory. We analyse all the conforma…
