Asymptotic structure of a massless scalar field and its dual two-form field at spatial infinity

Marc Henneaux, Cédric Troessaert

Journal of High Energy Physics > 2019 > 2019 > 5 > 1-31

Abstract Relativistic field theories with a power law decay in r^−k at spatial infinity generically possess an infinite number of conserved quantities because of Lorentz invariance. Most of these are not related in any obvious way to symmetry transformations of which they would be the Noether charges. We discuss the issue in the case of a massless scalar field. By going to the dual formulation in...

Three-dimensional conformal geometry and prepotentials for four-dimensional fermionic higher-spin fields

Marc Henneaux, Victor Lekeu, Amaury Leonard, Javier Matulich, more

Journal of High Energy Physics > 2018 > 2018 > 11 > 1-28

Abstract We introduce prepotentials for fermionic higher-spin gauge fields in four space-time dimensions, generalizing earlier work on bosonic fields. To that end, we first develop tools for handling conformal fermionic higher-spin gauge fields in three dimensions. This is necessary because the prepotentials turn out to be three-dimensional fields that enjoy both “higher-spin diffeomorphism” and...

article

Hamiltonian structure and asymptotic symmetries of the Einstein-Maxwell system at spatial infinity

Marc Henneaux, Cédric Troessaert

Journal of High Energy Physics > 2018 > 2018 > 7 > 1-23

Abstract We present a new set of asymptotic conditions for gravity at spatial infinity that includes gravitational magnetic-type solutions, allows for a non-trivial Hamiltonian action of the complete BM S₄ algebra, and leads to a non-divergent behaviour of the Weyl tensor as one approaches null infinity. We then extend the analysis to the coupled Einstein-Maxwell system and obtain as canonically...

The action of the (free) theory in six spacetime dimensions

Marc Henneaux, Victor Lekeu, Javier Matulich, Stefan Prohazka

Journal of High Energy Physics > 2018 > 2018 > 6 > 1-35

Abstract The action of the free theory in six spacetime dimensions is explicitly constructed. The variables of the variational principle are prepotentials adapted to the self-duality conditions on the fields. The (3, 1) supersymmetry variations are given and the invariance of the action is verified. The action is first-order in time derivatives. It is also Poincaré invariant but not manifestly so,...

article

Asymptotic symmetries of electromagnetism at spatial infinity

Marc Henneaux, Cédric Troessaert

Journal of High Energy Physics > 2018 > 2018 > 5 > 1-30

Abstract We analyse the asymptotic symmetries of Maxwell theory at spatial infinity through the Hamiltonian formalism. Precise, consistent boundary conditions are explicitly given and shown to be invariant under asymptotic angle-dependent u(1)-gauge transformations. These symmetries generically have non-vanishing charges. The algebra of the canonical generators of this infinite-dimensional symmetry...

Erratum to: The action of the (free) (4, 0)-theory

Marc Henneaux, Victor Lekeu, Amaury Leonard

Journal of High Energy Physics > 2018 > 2018 > 5 > 1-1

There are typos in equations (2.27), (A.15) and (C.22).

BMS group at spatial infinity: the Hamiltonian (ADM) approach

Marc Henneaux, Cédric Troessaert

Journal of High Energy Physics > 2018 > 2018 > 3 > 1-27

Abstract New boundary conditions for asymptotically flat spacetimes are given at spatial infinity. These boundary conditions are invariant under the BMS group, which acts non trivially. The boundary conditions fulfill all standard consistency requirements: (i) they make the symplectic form finite; (ii) they contain the Schwarzchild solution, the Kerr solution and their Poincaré transforms, (iii)...

Deformations of vector-scalar models

Glenn Barnich, Nicolas Boulanger, Marc Henneaux, Bernard Julia, more

Journal of High Energy Physics > 2018 > 2018 > 2 > 1-53

Abstract Abelian vector fields non-minimally coupled to uncharged scalar fields arise in many contexts. We investigate here through algebraic methods their consistent deformations (“gaugings”), i.e., the deformations that preserve the number (but not necessarily the form or the algebra) of the gauge symmetries. Infinitesimal consistent deformations are given by the BRST cohomology classes at ghost...

The action of the (free) (4, 0)-theory

Marc Henneaux, Victor Lekeu, Amaury Leonard

Journal of High Energy Physics > 2018 > 2018 > 1 > 1-29

Abstract The (4, 0) theory in six dimensions is an exotic theory of supergravity that has been argued to emerge as the strong coupling limit of theories having N = 8 supergravity as their low energy effective theory in five spacetime dimensions. It has maximal supersymmetry and is superconformal. Very little is known about this intriguing theory. While the spectrum of fields occurring in its description...

Timelike duality, M′-theory and an exotic form of the Englert solution

Marc Henneaux, Arash Ranjbar

Journal of High Energy Physics > 2017 > 2017 > 8 > 1-15

Abstract Through timelike dualities, one can generate exotic versions of M-theory with different spacetime signatures. These are the M^*-theory with signature (9, 2, −), the M′-theory, with signature (6, 5, +) and the theories with reversed signatures (1, 10, −), (2, 9, +) and (5, 6, −). In (s, t, ±), s is the number of space directions, t the number of time directions, and ± refers to the sign of...

Spacetime locality of the antifield formalism: General theorems illustrated by means of examples

Marc Henneaux

Lecture Notes in Physics > Integrable Models and Strings > 136-147

Some general techniques and theorems on the spacetime locality of the antifield formalism are illustrated in the familiar cases of the free scalar field, electromagnetism and Yang-Mills theory. Common misconceptions in the field are corrected.

Kac-Moody algebras and the structure of cosmological singularities: a new light on the Belinskii-Khalatnikov-Lifshitz analysis

Marc Henneaux

Quantum Mechanics of Fundamental Systems: The Quest for Beauty and Simplicity > CONTRIBUTED PAPERS > 1-11

The unexpected and fascinating emergence of hyperbolic Coxeter groups and Lorentzian Kac-Moody algebras in the investigation of gravitational theories in the vicinity of a cosmological singularity is briefly reviewed. Some open questions raised by this intriguing result, and some attempts to answer them, are outlined.

Quantum Mechanics of Fundamental Systems: The Quest for Beauty and Simplicity > CLOSING > 1-8

In life and work, Claudio Bunster prefers extreme challenges. Bunster, a physicist who contemplates brain-warping theories of space and time, returned to his native Chile from the United States precisely when most intellectuals would have stayed clear - during the middle of the Pinochet dictatorship. Shut out of the universities by the military government, he broke the conventional mold by founding...

In the name of the organizing committee, it is a great pleasure to welcome all of you to Claudio’s Fest, a meeting in which we shall celebrate the scientific work accomplished so far by Claudio. It has become customary to choose the 60th birthday for such celebrations and we have followed the tradition, although we all know that a scientific career does not stop at 60 and that we shall therefore miss...

Quantum Mechanics of Fundamental Systems: The Quest for Beauty and Simplicity

Jorge Zanelli, Marc Henneaux, Springer New York

In life and work, Claudio Bunster (formerly Teitelboim) prefers extreme challenges. Bunster, a physicist who contemplates brain-warping theories of space and time, returned to his native Chile from the United States precisely when most intellectuals would have stayed clear— during the middle of the Pinochet dictatorship (K. Mossman, Proceedings of the National Academy of Sciences) Against this...

Billiard Dynamics of Einstein-Matter Systems Near a Spacelike Singularity

Thibault Damour, Marc Henneaux, Hermann Nicolai

Series of the Centro De Estudios Científicos > Lectures on Quantum Gravity > 207-247

It is shown in detail that the dynamics in the vicinity of a spacelike singularity of the D-dimentional Einstein-dilaton-p-form system can be described, at each spatial point, as a billiard motion in a region of hyperbolic space. This is done within the Hamiltonian formalism. A key rôle is played in the derivation by the Iwasawa decomposition of the spatial metric. We also comment on the strong coupling/small...

Thermaldecay of the Cosmological Constant into Black Holes

Andrés Gomberoff, Marc Henneaux, Claudio Teitelboim, Frank Wilczek

Series of the Centro De Estudios Científicos > Lectures on Quantum Gravity > 329-349

We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle “going over the top of the potential barrier,” rather than tunneling through it. The membranes are endowed with charge associated with the gauge invariance of an antisymmetric gauge potential. In this new process, the membrane collapses into a black hole; thus,...

Higher spin conformal geometry in three dimensions and prepotentials for higher spin gauge fields

Marc Henneaux, Sergio Hörtner, Amaury Leonard

Journal of High Energy Physics > 2016 > 2016 > 1 > 1-30

Abstract We study systematically the conformal geometry of higher spin bosonic gauge fields in three spacetime dimensions. We recall the definition of the Cotton tensor for higher spins and establish a number of its properties that turn out to be key in solving in terms of prepotentials the constraint equations of the Hamiltonian (3 + 1) formulation of four-dimensional higher spin gauge fields. The...

Hypersymmetry bounds and three-dimensional higher-spin black holes

Marc Henneaux, Alfredo Pérez, David Tempo, Ricardo Troncoso

Journal of High Energy Physics > 2015 > 2015 > 8 > 1-25

Abstract We investigate the hypersymmetry bounds on the higher spin black hole parameters that follow from the asymptotic symmetry superalgebra in higher-spin anti-de Sitter gravity in three spacetime dimensions. We consider anti-de Sitter hypergravity for which the analysis is most transparent. This is a osp(1|4) ⊕ osp(1|4) Chern-Simons theory which contains, besides a spin-2 field, a spin-4 field...

Asymptotic symmetries of three-dimensional higher-spin gravity: the metric approach

Andrea Campoleoni, Marc Henneaux

Journal of High Energy Physics > 2015 > 2015 > 3 > 1-64

Abstract The asymptotic structure of three-dimensional higher-spin anti-de Sitter gravity is analyzed in the metric approach, in which the fields are described by completely symmetric tensors and the dynamics is determined by the standard Einstein-Fronsdal action improved by higher order terms that secure gauge invariance. Precise boundary conditions are given on the fields. The asymptotic...
