Anomaly Nucleation Constrains SU(2) Gauge Theories
James Halverson
We argue for the existence of additional constraints on SU(2) gauge theories in four dimensions when realized in ultraviolet completions admitting an analog of D-brane nucleation.…
Perturbative Corrections to Kahler Moduli Spaces
James Halverson, Hans Jockers, Joshua M. Lapan +1
We propose a general formula for perturbative-in-alpha' corrections to the Kahler potential on the quantum Kahler moduli space of Calabi-Yau n-folds, for any n, in their asymptotic…
Matter From Geometry Without Resolution
Antonella Grassi, James Halverson, Julius L. Shaneson
We utilize the deformation theory of algebraic singularities to study charged matter in compactifications of M-theory, F-theory, and type IIa string theory on elliptically fibered…
New Methods for Characterizing Phases of 2D Supersymmetric Gauge Theories
James Halverson, Vijay Kumar, David R. Morrison
We study the physics of two-dimensional N=(2,2) gauged linear sigma models (GLSMs) via the two-sphere partition function. We show that the classical phase boundaries separating dis…
