Gravity and generalised geometry from a Lie 2-algebroid perspective
Athanasios Chatzistavrakidis, Chris Hull, Larisa Jonke +2
We revisit the problem of defining natural torsion and curvature tensors for generalised connections and of using them to reconstruct the effective action for the massless modes of…
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…
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…
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.…
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…
