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…
Wehrl entropy, coherent states and quantum channels
Peter Schupp
We review Wehrl's definition of a semiclassical entropy in terms of coherent states and give an introductory overview of Lieb's conjecture, its proof (including earlier results), g…
Axion gravitodynamics, Lense-Thirring effect, and gravitational waves
Athanasios Chatzistavrakidis, Georgios Karagiannis, George Manolakos +1
We investigate physical implications of a gravitational analog of axion electrodynamics with a parity-violating gravitoelectromagnetic theta term. This is related to the Nieh-Yan t…
A gravitational action with stringy and fluxes via deformed differential graded Poisson algebras
E. Boffo, P. Schupp
We study a deformation of a -graded Poisson algebra where the functions of the phase space variables are complemented by linear functions of parity odd velocities. The deformati…
Torsion-induced gravitational term and gravitoelectromagnetism
Athanasios Chatzistavrakidis, Georgios Karagiannis, Peter Schupp
Motivated by the analogy between a weak field expansion of general relativity and Maxwell's laws of electrodynamics, we explore physical consequences of a parity violating term…
Graded Geometry and Tensor Gauge Theories
Athanasios Chatzistavrakidis, Georgios Karagiannis, Peter Schupp
We review the construction of Lagrangians for higher spin fields of mixed symmetry in the framework of graded geometry. The main advantage of the graded formalism in this context i…
