We consider the thermodynamics of rotating and charged asymptotically de Sitter (dS) black
holes. Using Hamiltonian perturbation-theory techniques, we derive three different first-law …

Surface charges and their algebra in interacting Lagrangian gauge field theories are
constructed out of the underlying linearized theory using techniques from the variational …

We review in simple terms the covariant approaches to the canonical formulation of classical
relativistic field theories (in particular gauge field theories and general relativity) and we …

A bstract The main focus of this work is to study magnetic soft charges of the four
dimensional Maxwell theory. Imposing appropriate asymptotic falloff conditions, we compute …

A bstract We derive the asymptotic symmetries of the manifestly duality invariant formulation
of electromagnetism in Minkoswki space. We show that the action is invariant under two …

The semiclassical contribution to the partition function is obtained by evaluating the
Euclidean action improved through suitable boundary terms. We address the question of …

We study electric and magnetic monopoles in static, spherically symmetric and constant
curvature geometries in the context of the inverse electrodynamics model. We prove that this …

We extend the formulation of spin 2 fields on Minkowski space which makes the action
manifestly invariant under duality rotations to the case of interactions with external electric …

A bstract Abelian vector fields non-minimally coupled to uncharged scalar fields arise in
many contexts. We investigate here through algebraic methods their consistent deformations …

A bstract We consider four-dimensional gravity in the presence of a dilatonic scalar field and
an Abelian gauge field. This theory corresponds to the bosonic sector of a Kaluza-Klein …
