Coherent states for FLRW space-times in loop quantum gravity
Elena Magliaro, Antonino Marciano, Claudio Perini
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaître-Robertson-Walker type on which they are peaked. The da…
Big Bounce in Dipole Cosmology
Marco Valerio Battisti, Antonino Marciano
We derive the cosmological Big Bounce scenario from the dipole approximation of Loop Quantum Gravity. We show that a non-singular evolution takes place for any matter field and tha…
Testing gravitational parity violation with coincident gravitational waves and short gamma-ray bursts
Nicolas Yunes, Richard O'Shaughnessy, Benjamin J. Owen +1
Gravitational parity violation is a possibility motivated by particle physics, string theory and loop quantum gravity. One effect of it is amplitude birefringence of gravitational…
Nonquantum Gravity
Stephen Boughn
One of the great challenges for 21st century physics is to quantize gravity and generate a theory that will unify gravity with the other three fundamental forces of nature. This pa…
Aspects of Graviton Detection: Graviton Emission and Absorption by Atomic Hydrogen
Stephen Boughn, Tony Rothman
Graviton absorption cross sections and emission rates for hydrogen are calculated by both semi-classical and field theoretic methods. We point out several mistakes in the literatur…
