Beyond Large Complex Structure: Quantized Periods and Boundary Data for One-Modulus Singularities
Brice Bastian, Damian van de Heisteeg, Lorenz Schlechter
We study periods in an integral basis near all possible singularities in one-dimensional complex structure moduli spaces of Calabi-Yau threefolds. Near large complex structure poin…
Engineering Small Flux Superpotentials and Mass Hierarchies
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
We study the stabilization of complex structure moduli in Type IIB flux compactifications by using recent general results about the form of the superpotential and Kähler potential…
Modeling General Asymptotic Calabi-Yau Periods
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
In the quests to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures we initiate the general study of asymptotic period vectors of Cala…
Weak Gravity Bounds in Asymptotic String Compactifications
Brice Bastian, Thomas W. Grimm, Damian van de Heisteeg
We study the charge-to-mass ratios of BPS states in four-dimensional supergravities arising from Calabi-Yau threefold compactifications of Type IIB string theory. W…
Symmetries in A-Type Little String Theories, Part II
Brice Bastian, Stefan Hohenegger
We continue our study of symmetries of a class of little string theories of A-type, which are engineered by parallel M5-branes probing a flat transverse space. Extending the an…
Symmetries in A-Type Little String Theories, Part I
Brice Bastian, Stefan Hohenegger
We analyse the symmetries of a class of A-type little string theories that are engineered by parallel M5-branes with M2-branes stretched between them. This paper deals with the…
Dihedral Symmetries of Gauge Theories from Dual Calabi-Yau Threefolds
Brice Bastian, Stefan Hohenegger
Recent studies (arXiv:1610.07916, arXiv:1711.07921, arXiv:1807.00186) of six-dimensional supersymmetric gauge theories that are engineered by a class of toric Calabi-Yau threefolds…
Five-Dimensional Gauge Theories from Shifted Web Diagrams
Brice Bastian, Stefan Hohenegger, Amer Iqbal +1
In previous works (arXiv:1610.07916, arXiv:1711.07921, arXiv:1807.00186) we studied a class of toric Calabi-Yau threefolds which engineer six-dimensional supersymmetric gauge theor…
Beyond Triality: Dual Quiver Gauge Theories and Little String Theories
Brice Bastian, Stefan Hohenegger, Amer Iqbal +1
The web of dual gauge theories engineered from a class of toric Calabi-Yau threefolds is explored. In previous work, we have argued for a triality structure by compiling evidence f…
Triality in Little String Theories
Brice Bastian, Stefan Hohenegger, Amer Iqbal +1
We study a class of eight-supercharge little string theories (LSTs) on the world-volume of M5-branes with transverse space . T…
Dual Little Strings and their Partition Functions
Brice Bastian, Stefan Hohenegger, Amer Iqbal +1
We study the topological string partition function of a class of toric, double elliptically fibered Calabi-Yau threefolds at a generic point in the Kähler moduli space. T…
Five-Brane Webs and Highest Weight Representations
Brice Bastian, Stefan Hohenegger
We consider BPS-counting functions of parallel M5-branes probing a transverse orbifold geometry. These brane web configurations can be dualis…
