Cosmological insight into fundamental physics
Abstract: Tamara Davis The last decade of astrophysics has shown more than ever before that cosmology can teach us about the nuts-and-bolts of basic physics. This has been driven by the discovery of the accelerating universe (dark energy) --- the theories being proposed to explain dark energy often invoke ne... read more

PIRSA:10120051  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Scale invariance, Weyl gravity, and Einstein's three objections
Speaker(s): Hans Westman
Abstract: Basic epistemological considerations suggest that the laws of nature should be scale invariant and no fundamental length scale should exist in nature. Indeed, the standard model action contains only two terms that break scale invariance: the Einstein-Hilbert term and the Higgs mass term. We give a s... read more

PIRSA:10120052  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Local scale invariance as an alternative to Lorentz invariance
Speaker(s): Sean Gryb
Abstract: I will present a recent result showing that general relativity admits a dual description in terms of a 3D scale invariant theory. The dual theory was discovered by starting with the basic observation that, fundamentally, all observations can be broken down into local comparisons of spatial configura... read more

PIRSA:10120053  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum limits for measurement of the metric tensor
Abstract: Tony Downes The geometry of space-time can only be determined by making measurements on physical systems. The ultimate accuracy achievable is then determined by quantum mechanics which fundamentally governs these systems. In this talk I will describe uncertainty principles constraining how well we ... read more

PIRSA:10120054  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum information theory in curved spacetime
Speaker(s): Maki Takahashi
Abstract: Maki Takahashi We present a formalism describing the transport of the quantum spin state of massive fermions in curved space-time for the purpose of studying relativistic quantum information phenomena such as entanglement and teleportation. We are concerned with answering the elementary question of... read more

PIRSA:10120055  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Protective Measurement and the Interpretation of the Wave Function
Abstract: Shan Gao We investigate the validity of the field explanation of the wave function by analyzing the mass and charge density distributions of a quantum system. According to protective measurement, a charged quantum system has effective mass and charge density distributed in space, proportional to th... read more

PIRSA:10120056  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A quantization quandary on the canonical road to quantum gravity
Speaker(s): Karim Thebault
Abstract: Karim Thebault Canonical quantization techniques are generally considered to provide one of the most rigorous methodologies for passing from a classical to a quantum description of reality. For classical Hamiltonian systems with constraints a number of such techniques are available (i.e. gauge fixi... read more

PIRSA:10120058  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The complementary contributions of free will, indeterminism and signalling to models of quantum correlations
Speaker(s): Michael Hall
Abstract: To model statistical correlations that violate Bell inequalities (such as singlet state correlations), one must relax at least one of three physically plausible postulates: measurement independence (experimenters can freely choose measurement settings independently of any underlying variables descri... read more

PIRSA:10120059  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum non-locality: how much does it take to simulate quantum correlations?
Speaker(s): Cyril Branciard
Abstract: Quantum correlations cannot be given any classical explanation that would satisfy Bell's local causality assumption. This quite intriguing feature of quantum theory, known as quantum non-locality, has fascinated physicists for years, and has more recently been proven to have interesting applications... read more
