Supersymmetric Poisson and Poisson-supersymmetric sigma models
Thomas Basile, Athanasios Chatzistavrakidis, Sylvain Lavau
We revisit and construct new examples of supersymmetric 2D topological sigma models whose target space is a Poisson supermanifold. Inspired by the AKSZ construction of topological…
Tensor global symmetries and the Stueckelberg mechanism for tensor fields
Athanasios Chatzistavrakidis, Arash Ranjbar, Sara Zeko
We investigate the concept of tensor global symmetries, featuring conserved currents of mixed symmetry and higher spin Nambu-Goldstone bosons. We develop a Stueckelberg mechanism f…
Brane mechanics and gapped Lie n-algebroids
Athanasios Chatzistavrakidis, Toni Kodžoman, Zoran Škoda
We draw a parallel between the BV/BRST formalism for higher-dimensional () Hamiltonian mechanics and higher notions of torsion and basic curvature tensors for generalized co…
Geometric BV for twisted Courant sigma models and the BRST power finesse
Athanasios Chatzistavrakidis, Noriaki Ikeda, Larisa Jonke
We study twisted Courant sigma models, a class of topological field theories arising from the coupling of 3D 0-/2-form BF theory and Chern-Simons theory and containing a 4-form Wes…
Basic curvature and the Atiyah cocycle in gauge theory
Athanasios Chatzistavrakidis, Larisa Jonke
Motivated from target space covariant formulations of topological sigma models and from a graded-geometric approach to higher gauge theory, we study connections on Lie and Courant…
Instances of Higher Geometry in Field Theory
Athanasios Chatzistavrakidis
Generalisations of geometry have emerged in various forms in the study of field theory and quantization. This mini-review focuses on the role of higher geometry in three selected p…
