Is the Born Rule Unstable in Quantum Gravity?
Speaker(s): Antony Valentini
Abstract: We argue that in quantum gravity there is no stable equilibrium state corresponding to the Born rule. Our main argument rests on the continued controversy over the physical meaning of the Wheeler-DeWitt equation. We suggest that attempts to interpret it are hampered by the conventional assumption th... read more

Testing Quantum Mechanics in the Early Universe
Speaker(s): Antony Valentini
Abstract: Hidden-variables theories account for quantum mechanics in terms of a particular 'equilibrium' distribution of underlying parameters corresponding to the Born rule. In the most well-studied example, the pilot-wave theory of de Broglie and Bohm, it is well established that the Born rule may be unders... read more

Stability of Hidden-Variables Theories: De Broglie Versus Bohm
Speaker(s): Antony Valentini
Abstract: Hidden-variables theories account for quantum mechanics in terms of a particular 'equilibrium' distribution of underlying parameters corresponding to the Born rule. A natural question to ask is whether the theory is stable under small perturbations away from equilibrium. We compare and contrast two ... read more

Beyond the Quantum
Speaker(s): Antony Valentini
Abstract: According to hidden-variables theories, quantum physics is a special 'equilibrium' case of a much wider 'nonequilibrium' physics. We describe the search for that wider physics in a cosmological context. The hypothesis that the universe began in a state of quantum nonequilibrium is shown to have obse... read more

The nature of the wave function in de Broglie's pilot-wave theory

Inflationary cosmology as a probe of primordial quantum mechanics
Speaker(s): Antony Valentini
Abstract: It is shown that inflationary cosmology may be used to test the statistical predictions of quantum theory at very short distances. Hidden-variables theories, such as the pilot-wave theory of de Broglie and Bohm, allow the existence of vacuum states with non-standard field fluctuations (“quantum non... read more
