How Much Can Gravitons Be Squeezed?
Panagiotis Dorlis, Nick E. Mavromatos, Sarben Sarkar +1
Quantum Gravity remains elusive, largely because its observable effects are suppressed by powers of the Planck scale. Direct detection of single gravitons is widely believed to be…
Axions, Black Holes and the Detection of Gravitons: from Astrophysics to Cosmology
Nick E. Mavromatos, Panagiotis Dorlis, Sarben Sarkar +1
We review a novel scenario for the emergence of spin-polarisation entangled squeezed graviton states from superradiant axionic clouds in the neighborhood of astrophysical rotating…
Squeezed gravitons from superradiant axion fields around rotating black holes
Panagiotis Dorlis, Nick E. Mavromatos, Sarben Sarkar +1
We propose, in (3+1)-dimensional spacetimes, a novel astrophysical source of squeezed graviton states, due to superradiant axionic clouds surrounding rotating (Kerr-type) black hol…
Torsion-induced axions in string theory, quantum gravity and the cosmological tensions
Nick E. Mavromatos, Panagiotis Dorlis, Sotirios-Neilos Vlachos
We discuss the role of torsion in string theory on inducing pseudoscalar degrees of freedom (axions), which in turn couple to (gravitational) Chern-Simons (CS) anomalous terms. Suc…
