Asymptotically locally flat spacetimes and dynamical black flowers in three dimensions
Glenn Barnich, Cédric Troessaert, David Tempo +1
The theory of massive gravity proposed by Bergshoeff, Hohm and Townsend is considered in the special case of the pure irreducibly fourth order quadratic Lagrangian. It is shown tha…
Super-BMS invariant boundary theory from three-dimensional flat supergravity
Glenn Barnich, Laura Donnay, Javier Matulich +1
The two-dimensional super-BMS invariant theory dual to three-dimensional asymptotically flat supergravity is constructed. It is described by a constrained or…
Chern-Simons action for inhomogeneous Virasoro group as an extension of three dimensional flat gravity
Glenn Barnich, Gaston Giribet, Mauricio Leston
We initiate the study of a Chern-Simons action associated to the semi-direct sum of the Virasoro algebra with its coadjoint representation. This model extends the standard Chern-Si…
Notes on conformal invariance of gauge fields
Glenn Barnich, Xavier Bekaert, Maxim Grigoriev
In Lagrangian gauge systems, the vector space of global reducibility parameters forms a module under the Lie algebra of symmetries of the action. Since the classification of global…
Notes on the BMS group in three dimensions: II. Coadjoint representation
Glenn Barnich, Blagoje Oblak
The coadjoint representation of the BMS group, which governs the covariant phase space of three-dimensional asymptotically flat gravity, is investigated. In particular, we clas…
One-loop partition function of three-dimensional flat gravity
Glenn Barnich, Hernan A. Gonzalez, Alexander Maloney +1
In this note we point out that the one-loop partition function of three-dimensional flat gravity, computed along the lines originally developed for the anti-de Sitter case, reprodu…
