Gravitational Cheshire effect: Nonminimally coupled scalar fields may not curve spacetime
Eloy Ayón-Beato, Cristián Martínez, Ricardo Troncoso +1
It is shown that flat spacetime can be dressed with a real scalar field that satisfies the nonlinear Klein-Gordon equation without curving spacetime. Surprisingly, this possibility…
11D Supergravity as a gauge theory for the M-algebra
Mokhtar Hassaine, Ricardo Troncoso, Jorge Zanelli
The eleven-dimensional gravitational action invariant under local Poincare transformations is given by the dimensional continuation of the Euler class of ten dimensions. Here we sh…
Vacuum Energy in Odd-Dimensional AdS Gravity
P. Mora, R. Olea, R. Troncoso +1
A background-independent, Lorentz-covariant approach to compute conserved charges in odd-dimensional AdS gravity, alternative to the standard counterterms method, is presented. A s…
