This does not require the introduction of additional matter fields with ad hoc potentials; rather, it occurs because of a quantum gravity modification of the kinetic part of ordinary matter Hamiltonians. An application of the same mechanism can explain why the present-day cosmological acceleration is so tiny.4 pages, 3 figuresGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - Theorytext
