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…
Two-Sphere Partition Functions and Gromov-Witten Invariants
Hans Jockers, Vijay Kumar, Joshua M. Lapan +2
Many N=(2,2) two-dimensional nonlinear sigma models with Calabi-Yau target spaces admit ultraviolet descriptions as N=(2,2) gauge theories (gauged linear sigma models). We conjectu…
Nonabelian 2D Gauge Theories for Determinantal Calabi-Yau Varieties
Hans Jockers, Vijay Kumar, Joshua M. Lapan +2
The two-dimensional supersymmetric gauged linear sigma model (GLSM) with abelian gauge groups and matter fields has provided many insights into string theory on Calabi--Yau manifol…
N=1 Sigma Models in AdS_4
Allan Adams, Hans Jockers, Vijay Kumar +1
We study sigma models in AdS_4 with global N=1 supersymmetry and find that they differ significantly from their flat-space cousins -- the target space is constrained to be a Kahler…
6D supergravity without tensor multiplets
Vijay Kumar, Daniel S. Park, Washington Taylor
We systematically investigate the finite set of possible gauge groups and matter content for N = 1 supergravity theories in six dimensions with no tensor multiplets, focusing on no…
Global aspects of the space of 6D N = 1 supergravities
Vijay Kumar, David R. Morrison, Washington Taylor
We perform a global analysis of the space of consistent 6D quantum gravity theories with N = 1 supersymmetry, including models with multiple tensor multiplets. We prove that for th…
