On the unexpected geometrical origin of the algebra of symmetries
O. Ramírez, Y. Bonder
The fundamental symmetries in gravity and gauge theories, formulated using differential forms, are gauge transformations and diffeomorphisms. These symmetries act in distinct ways…
Unimodular gravity as an initial value problem
J. E. Herrera, Y. Bonder
Unimodular gravity is a compelling modified theory of gravity that offers a natural solution to the cosmological constant problem. However, for unimodular gravity to be considered…
Are inertial vacua equivalent in Lorentz-violating theories? Does it matter?
Bruno Arderucio Costa, Yuri Bonder, Benito A. Juárez-Aubry
Several approaches to quantum gravity suggest violations of Lorentz symmetry as low-energy signatures. This article uses a concrete Lorentz-violating quantum field theory to study…
Energy nonconservation and relativistic trajectories: Unimodular gravity and beyond
Y. Bonder, J. E. Herrera, A. M. Rubiol
Energy conservation has the status of a fundamental physical principle. However, measurements in quantum mechanics do not comply with energy conservation. Therefore, it is expected…
On the Hamiltonian of gravity theories whose action is linear in spacetime curvature
Yuri Bonder
A straightforward method to compute Hamilton's density for theories that are linear in the spacetime curvature is provided. It is shown that the lapse function and shift vector sti…
Bell's nonlocality and gravity
Yuri Bonder, Johas D. Morales
The experimental results that test Bell's inequality have found strong evidence suggesting that there are nonlocal aspects in nature. Evidently, these nonlocal effects, which conce…
