2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/216579We investigate the behaviour of tensor fluctuations in Loop Quantum Cosmology, focusing on a class of scaling solutions which admit a near scale-invariant scalar field power spectrum. We obtain the spectral index of the gravitational field perturbations, and find a strong blue tilt in the power spectrum with $n_t \approx 2$. The amplitude of tensor modes are, therefore, suppressed by many orders of magnitude on large scales compared to those predicted by the standard inflationary scenario where $n_t \approx 0$.8 pages, 3 figuresAstrophysicsGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
