On a Deformed Holomorphic Chern-Simons Theory

Eirik Høgmoe Kjelsnes, Eirik Eik Svanes, Vegard Undheim

We deform classical holomorphic Chern--Simons theory on a Calabi--Yau three-fold by deforming the complex structure by a deformation parameter $h \in\mathscr{H}^{0,1}(T^{1,0}X)…

Holomorphic supergravity in ten dimensions and anomaly cancellation

Anthony Ashmore, Javier José Murgas Ibarra, Charles Strickland-Constable +1

We formulate a ten-dimensional version of Kodaira-Spencer gravity on a Calabi-Yau five-fold that reproduces the classical Maurer-Cartan equation governing supersymmetric heterotic…

The heterotic moduli space metric

Jock McOrist, Martin Sticka, Eirik Eik Svanes

In this article we dimensionally reduce a heterotic supergravity on a background with Minkowski spacetime using a certain cohomology as a basis for the Kaluza-Klein expansion…

The moduli of the universal geometry of heterotic moduli

Jock McOrist, Martin Sticka, Eirik Eik Svanes

We study the moduli of the universal geometry of heterotic vacua. Universal geometry refers to a family of heterotic vacua fibered over the moduli space. The universal…

Quantum aspects of heterotic systems

Xenia de la Ossa, Magdalena Larfors, Matthew Magill +1

Compactifications of the heterotic string, to first order in the expansion, on manifolds with integrable structure give rise to three-dimensional supergra…

The decoupling of moduli about the standard embedding

Beatrice Chisamanga, Jock McOrist, Sebastien Picard +1

We study the cohomology of an elliptic differential complex arising from the infinitesimal moduli of heterotic string theory. We compute these cohomology groups at the standard emb…

The physical moduli of heterotic G_2 string compactifications

Jock McOrist, Martin Sticka, Eirik Eik Svanes

In previous works, an operator was developed for heterotic compactifications on and , which preserves supersymmetry and w…

Local descriptions of the heterotic SU(3) moduli space

Hannah de Lázari, Jason D. Lotay, Henrique Sá Earp +1

The heterotic system, also known as the Hull--Strominger system, arises from compactifications of heterotic string theory to six dimensions. This paper investigates the loc…

BPS complexes and Chern--Simons theories from -structures in gauge theory and gravity

Julian Kupka, Charles Strickland-Constable, Eirik Eik Svanes +2

We consider a variety of physical systems in which one has states that can be thought of as generalised instantons. These include Yang--Mills theories on manifolds with a torsion-f…

A Heterotic Kähler Gravity and the Distance Conjecture

Javier José Murgas Ibarra, Paul-Konstantin Oehlmann, Fabian Ruehle +1

Deformations of the heterotic superpotential give rise to a topological holomorphic theory with similarities to both Kodaira-Spencer gravity and holomorphic Chern-Simons theory. Al…

Vegard Undheim, Alex Bentley Nielsen, Eirik Eik Svanes

Within the framework of string theory, a number of new fields are possible correcting the Einstein-Hilbert action, including a Kalb-Ramond two-form field. In this work we derive ex…

A heterotic Kodaira-Spencer theory at one-loop

Anthony Ashmore, Javier José Murgas Ibarra, David Duncan McNutt +4

We consider a heterotic version of six-dimensional Kodaira-Spencer gravity derived from the heterotic superpotential. We compute the one-loop partition function and find it can be…

A note on Real line bundles with connection and Real smooth Deligne cohomology

Peter Marius Flydal, Gereon Quick, Eirik Eik Svanes

We define a Real version of smooth Deligne cohomology for manifolds with involution which interpolates between equivariant sheaf cohomology and smooth imaginary-valued forms. Our m…

Heterotic Quantum Cohomology

Jock McOrist, Eirik Eik Svanes

We reexamine the massless spectrum of a heterotic string vacuum at large radius and present two results. The first result is to construct a vector bundle and operator…

Gauging Discrete Symmetries of -theories in Five Dimensions

Bobby Acharya, Neil Lambert, Marwan Najjar +2

We study the gauging of a discrete symmetry in the five-dimensional superconformal theories. We argue that this leads to an infinite sequence of five-dimension…
