Thick branes and fermion localization in five-dimensional gravity
A. R. P. Moreira, F. M. Belchior, Shi-Hai Dong +1
We investigate thick-brane configurations in five-dimensional modified teleparallel gravity. In five dimensions, the torsional Gauss-Bonnet invariant contributes d…

Holographic dark energy from a new two-parameter entropic functional
G. G. Luciano, E. N. Saridakis
We formulate an extended holographic dark energy scenario based on a recently proposed two-parameter generalized entropic functional. Unlike constructions that phenomenologically i…

White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
