Adiabatically-induced Kawaguchi geometry and jerk in quantum-classical systems
Athanasios Chatzistavrakidis, Larisa Jonke, Ryan Requist
Adiabatically eliminating the quantum degrees of freedom in a mixed quantum-classical system produces an effective force in the classical equation of motion. The elimination can be…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
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…
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…
