A first step towards the inflationary trans-planckian problem treatment in Loop Quantum Cosmology
Killian Martineau, Aurélien Barrau, Julien Grain
For most initial conditions, cosmologically relevant physical modes were trans-planckian at the bounce time, often by many magnitude orders. We improve the usual loop quantum cosmo…

Julien Grain, Vincent Vennin
An appealing feature of inflationary cosmology is the presence of a phase-space attractor, "slow roll", which washes out the dependence on initial field velocities. We investigate…
