Searching for New Particles with Black Hole Superradiance
Black hole superradiance is a fascinating process in general relativity and a unique window on ultralight particles beyond the standard model. Bosons -- such as axions and dark photons -- with Compton wavelengths comparable to size of astrophysical black holes grow exponentially to form large clouds -

Algorithmic Information, Induction and Observers in Physics
Our universe is of astonishing simplicity: almost all physical observations can in principle be described by a few theories that have short mathematical descriptions. But there is a field of computer science which quantifies simplicity namely algorithmic information theory (AIT). In this workshop we -
Observers in Quantum and Foil Theories
Foil theories sometimes called mathematically rigorous science fiction describe ways the world could have been were it not quantum mechanical. Our understanding of quantum theory has been deepened by contrasting it with these alternatives. So far observers in foil theories have only been modeled -
Open Research: Rethinking Scientific Collaboration
Scientific inquiry in the 21st century is beset with inefficiencies: a flood of papers not read theories not tested and experiments not repeated; a narrow research agenda driven by a handful of high-impact journals; a publishing industry that turns public funding into private profit; the exclusion -
Gauge Theory, Geometric Langlands and Vertex Operator Algebras
The workshop will explore the relation between boundary conditions in four-dimensional gauge theory the Geometric Langlands program and Vertex Operator Algebras. -
The Path Integral for Gravity
Over the past three decades, the idea of a path integral over geometries, describing gravity in various dimensions, has become increasingly central to many areas of theoretical physics, including string and M-theory, holography and quantum aspects of black holes and cosmology. In each of these areas -
Quantum Black Holes in the Sky?
The past decade has witnessed significant breakthroughs in understanding the quantum nature of black holes, with insights coming from quantum information theory, numerical relativity, and string theory. At the same time, astrophysical and gravitational wave observations can now provide an -
Experimental techniques in table-top fundamental physics
In the last few years there has been a resurgence of interest in small scale high sensitivity experiments that look for new forces and new particles beyond the Standard Model. They promise to expand our understanding of the Cosmos and possibly explain mysteries such as Dark matter in a way that is -
Hopf Algebras in Kitaev's Quantum Double Models: Mathematical Connections from Gauge Theory to Topological Quantum Computing and Categorical Quantum Mechanics
-18 talks C17029 Conference/School Condensed Matter Mathematical physics Quantum Foundations Quantum Gravity Quantum InformationThe Kitaev quantum double models are a family of topologically ordered spin models originally proposed to exploit the novel condensed matter phenomenology of topological phases for fault-tolerant quantum computation. Their physics is inherited from topological quantum field theories, while their -
Contextuality: Conceptual Issues, Operational Signatures, and Applications
2017 marks 50 years since the seminal 1967 article of Kochen and Specker proving that quantum theory fails to admit of a noncontextual model. Despite the fact that the Kochen-Specker theorem is one of the seminal results concerning the foundations of quantum theory, there has never been a large -
New Directions in Dark Matter and Neutrino Physics
Continuing investment in fundamental weakly-coupled science, primarily through neutrino experiments and dark matter searches, prompts the question: is the maximum possible scientific information going to be extracted from these experiments? Are there new creative uses of the existing and planned
