A manifestly gauge-invariant formulation of the coupling of the Maxwell theory with an
Einstein-Cartan geometry is given, where the spacetime torsion originates from a massless …

We consider BF-type topological field theory coupled to non-dynamical particle and string
sources on spacetime manifolds of the form R1× M 3, where M 3 is a 3-manifold without …

Taking the simple examples of an Abelian 1-form gauge theory in two (1+ 1)-dimensions, a 2-
form gauge theory in four (3+ 1)-dimensions and a 3-form gauge theory in six (5+ 1) …

Gauge theories on manifolds with spatial boundaries are studied. It is shown that
observables localized at the boundaries (edge observables) can occur in such models …

We extend all known black-hole no-hair theorems to space-times endowed with a positive
cosmological constant Λ. Specifically, we prove that static spherical black holes with Λ> 0 …

We show that the Becchi-Rouet-Stora-Tyutin (BRST)/anti-BRST invariant (3+ 1)-dimensional
two-form gauge theory has further nilpotent symmetries (dual BRST/anti-dual BRST) that …

A non-local yet gauge-invariantly massive 2-form model is considered that leads to local and
unitary dynamics upon proper gauge-fixing. Since canonical momenta cannot be defined …

When an antisymmetric tensor potential is coupled to the field strength of a gauge field via a
B∧ F coupling and a kinetic term for B is included, the gauge field develops an effective …

We present a new family of exact black hole configurations, which is a solution to a
generalized Einstein-Maxwell-Dilaton setup in arbitrary dimension. These solutions are …

The addition of mass terms in general breaks gauge symmetries which can be recovered
usually via Stueckelberg fields. The massive BF model describes massive spin-1 particles …
