What the Reeh-Schielder theorem tells us about relativistic causality, or, Can experimenters in a lab on Earth create a Taj Mahal on the back of the moon?
Wayne Myrvold - Western University
The Reeh-Schlieder theorem says, roughly, that, in any reasonable quantum field theory, for any bounded region of spacetime R, any state can be approximated arbitrarily closely by operating on the vacuum state (or any state of bounded energy) with operators formed by smearing polynomials in the…
Multitude of percolative orders: Infinite cascades of geometric phase transitions
Gennady Chitov - Laurentian University
The evolution of many kinetic processes in 1+1 dimensions results in 2D directed percolative landscapes. The active phases of those models possess numerous hidden geometric orders characterized by distinct percolative patterns. From Monte-Carlo simulations of the directed percolation (DP) and the…
Supersymmetric flavors on curved space and a precision test of AdS/CFT
Christoph Uhlemann - Vrije Universiteit Brussel
Quantum field theory on curved space has long been studied for its interesting phenomenology, and more recently also as a means to obtain non-perturbative results in supersymmetric theories. In this talk I will describe the holographic dual for N=4 SYM coupled to massive N=2 flavors on spaces of…
Kinetic Terms in Massive gravity
Is the graviton a truly massless spin-2 particle, or can the graviton have a small mass? If the mass of the graviton is of order the Hubble scale today, it can potentially help to explain the observed cosmic acceleration. Previous attempts to study massive gravity have been spoiled by the fact that…

Fault-tolerant error correction with the gauge color code
Benjamin Brown - University of Sydney
The gauge color code is a quantum error-correcting code with local syndrome measurements that, remarkably, admits a universal transversal gate set without the need for resource-intensive magic state distillation. A result of recent interest, proposed by Bombin, shows that the subsystem structure of…
BV-BFV Approach to General Relativity
Michele Schiavina - ETH Zurich
We analyse different classical formulations of General Relativity in the Batalin (Frad- kin) Vilkovisky framework with boundary, as a first step in the program of CMR [1] quantisation. Success and failure in satisfying the axioms will allow us to discriminate among the different descriptions…
Representations of truncated shifted Yangians and symplectic duality
Joel Kamnitzer - University of Toronto
We study the representation theory of truncated shifted Yangians. These algebras arise as quantizations of slices to Schubert varieties in the affine Grassmannian. We will describe the combinatorics of their highest weights, which is encoded in Nakajima's monomial crystal. We also prove Hikita's…
