Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
Topological Classification of Symmetry Breaking and Vacuum Degeneracy
Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1
We argue that a general system of scalar fields and gauge fields manifesting vacuum degeneracy induces a principal groupoid bundle over spacetime and that the pattern of spontaneou…
Adjusted Connections I: Differential Cocycles for Principal Groupoid Bundles with Connection
Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1
We develop a new perspective on principal bundles with connection as morphisms from the tangent bundle of the underlying manifold to a classifying dg-Lie groupoid. This groupoid ca…
