What discrete states have a continuum limit?
Gemma De Las Cuevas - Universität Innsbruck
PIRSA:15050075 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationRenormalization to low energies is widely used in condensed matter theory to reveal the low energy degrees of freedom of a system, or in high energy physics to cure divergence problems. Here we ask which states can be seen as the result of such a renormalization procedure, that is, which states can…
Tangent field theory
Cédric Bény - Leibniz University Hannover
PIRSA:15050092 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationThe modern understanding of quantum field theory underlines its effective nature: it describes only those properties of a system relevant above a certain scale. A detailed understanding of the nature of the neglected information is essential for a full application of quantum information-theoretic…
Entropic Dynamics: from Entropy and Information Geometry to Quantum Mechanics
Ariel Caticha - State University of New York (SUNY)
PIRSA:15050091 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationOur subject is Entropic Dynamics, a framework that emphasizes the deep connections between the laws of physics and information. In attempting to understand quantum theory it is quite natural to assume that it reflects laws of physics that operate at some deeper level and the goal is to discover what…
Quantum information geometric foundations: beyond the spectral paradigm
Ryszard Kostecki - Slovak Academy of Sciences
PIRSA:15050090 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationIn the last decade there were proposed several new information theoretic frameworks (in particular, symmetric monoidal categories and "operational" convex sets), allowing for an axiomatic derivation of finite dimensional quantum mechanics as a specific case of a larger universe of information…
Quantum phenomena modelled by interactions between many classical worlds
Dirk-André Deckert - Ludwig-Maximilians-Universität München (LMU)
One necessity to avoid the measurement problem in quantum mechanics is a clear ontology. Such an ontology is for instance provided by Bohmian mechanics. In the non-relativistic regime, Bohmian mechanics is a theory about particles whose motion is governed by a velocity field. The latter is generated…
Quantum information and the algebraic structure of quantum gravity

Scanning the Horizon: Information, Holography and Gravity
Robert Myers - Perimeter Institute for Theoretical Physics
PIRSA:15050086 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationIn science, we often see new advances and insights emerging from the intersection of different ideas coming from what appeared to be disconnected research areas. The theme of my seminar will be an ongoing collision between the three topics listed in my title which has been generating interesting new…
Physical records and emergence of information in the gravitationally dominated universe
Tim Koslowski - Technical University of Applied Sciences Würzburg-Schweinfurt
PIRSA:15050085 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationThe second law of thermodynamics appears to be a universal law of physics. This universality suggests that entropy and with it information theory is part of the foundations of physics. In this talk I take the opposite (probably more conservative) approach: I assume that the dynamics of relational…
How far can you stretch classical mechanics?
Daniel Terno - Macquarie University
PIRSA:15050083 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationClassical and quantum theories are very different, but the gap between them may look narrow particularly if the notion of classicality is broadened. For example, if we do not impose all the classical assumptions at the same time, hidden variable theories reproduce the results of quantum mechanics…
Quantum mechanics from first principles
Lee Smolin - Perimeter Institute for Theoretical Physics
PIRSA:15050087 Conference Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationQuantum mechanics is derived from the principle that the universe contain as much variety as possible, in the sense of maximizing the distinctiveness of each subsystem. This is an expression of Leibniz's principles of sufficient reason and the identity of the indiscernible. The quantum state of a…
Entanglement Entropy in AdS3/CFT2: anomalies and fake gaps
Alejandra Castro - University of Cambridge
The concept of quantum entanglement entropy is playing a key role in understanding the mechanism underlying holography. In this talk we will discuss how entanglement can capture non-trivial geometric properties of the bulk spacetime. The goal is to exploit the interplay between anomalies and…
