PIRSA:13050068  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Energy diffusion from relativistic spontaneous localization
Speaker(s): Daniel Bedingham
Abstract: We discuss energy diffusion due to spontaneous localization (SL) for a relativistically-fast moving particle. Based on evidence from relativistic extensions of SL we argue that non-relativistic SL should remain valid in the particle rest frame. This implies that calculations can be performed by tran... read more

Why look beyond quantum theory?
Speaker(s): Richard Healey
Abstract: Quantum theory does not define its own landscape. We structure the landscape in response to some contemplated inadequacy of quantum theory. Much foundational work has been motivated by perceived conceptual inadequacies associated with non-locality and the measurement problem. By denying the descript... read more

PIRSA:13050070  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Conjugates, Correlation and the Jordan Structure of Finite-Dimensional Quantum Theory
Speaker(s): Alex Wilce
Abstract: The last few years have seen a spate of operational or information-theoreticderivations (or reconstructions") of  nite-dimensional quantum mechanics [1].  These rest of some strong assumptions. In particular, most assume the state of a composite system is entirely determined by the... read more

PIRSA:13050071  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Towards a realist's interpretation of the path integral
Speaker(s): Petros Wallden
Abstract: Having a fundamental spacetime view of physics, appears more justified in attempting to construct a quantum theory of gravity. In this talk, motivated by the latter,  a path integral approach is adopted and an attempt to construct a self-consistent realistic histories formulation of quantum... read more

PIRSA:13050072  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Time, cosmology and quantum foundations
Speaker(s): Lee Smolin
Abstract: I argue that quantum mechanics cannot usefully  be extended to a theory of the whole universe, so the task of quantum foundations is to discover that cosmological theory which reduces to quantum mechanics when restricted to small subsystems of the universe.  I argue that that cosmo... read more

Characterizing quantum non-locality: a histories approach
Speaker(s): Joe Henson
Abstract: Characterising quantum non-locality using simple physical principles has become a hot topic in quantum foundations of late.  In the simpler case of local hidden variable models, the space of allowed correlations can be characterised by requiring that there exists a joint probability distrib... read more
