11:30h     First Talk

Speaker: Carlo Rovelli (CPT & Aix-Marseille University, France)

Title: Dark matter as a quantum gravity phenomenon?

Abstract: If there are enough small (<10^12 Kg) primordial black holes, and if the indications of Loop Quantum Gravity are correct, then there should be dark matter. It should be formed by a dust of semistable black hole remnants, with mass around 10 micrograms, which interact gravitationally only. 

15:00h     Second Talk

Speaker: Etera Livine (ENS de Lyon, France)

Title: Dynamics of Loop Quantum Gravity

Abstract: I will review how to implement the dynamics of spin networks - the quantum states of geometry - in loop quantum gravity, in complementary ways as Hamiltonian evolution and through a path integral formalism. I will show how this dynamics can be studied explicitly on elementary blocks of spin networks and I will discuss the recent advances in the field.
