Flocking: Influence of Metric Versus Topological Interactions
Vijay Kumar, Rumi De
Flocking is a fascinating phenomenon observed across a wide range of living organisms. We investigate, based on a simple self-propelled particle model, how the emergence of ordered…
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…
