Cosmological Polytopes
Paolo Benincasa - Max Planck Institute for Physics (Werner Heisenberg Institute)
The properties of physical processes reflect themselves in the structure of the relevant observables. This idea has been largely exploited for the flat space S-matrix, whose analytic structure is determined by locality and unitary, the two pillars which our current understanding of nature is based…

Traces of intertwiners for quantum affine sl_2, affine Macdonald conjectures, and Felder-Varchenko functions
Yi Sun - Columbia University
This talk concerns a family of special functions common to the study of quantum conformal blocks and hypergeometric solutions to q-KZB type equations. In the first half, I will explain two methods for their construction -- as traces of intertwining operators between representations of quantum affine…
Entangling with Topological Quantum Matter
Topological phases of matter serve as one of the most striking examples of the richness and novelty of quantum systems with many degrees of freedom. In contrast to conventional matter, they are characterized by both non-local properties and non-classical notions such as entanglement. I will discuss…

Hyper-invariant tensor networks and holography
Glen Evenbly - Georgia Institute of Technology
PIRSA:17040049 Conference Condensed Matter Quantum Fields and Strings Quantum Gravity Quantum InformationI will propose a new class of tensor network state as a model for the AdS/CFT correspondence and holography. This class shall be demonstrated to retain key features of the multi-scale entanglement renormalization ansatz (MERA), in that they describe quantum states with algebraic correlation…
Tensor network and (p-adic) AdS/CFT
Ling-Yan Hung - Tsinghua University
PIRSA:17040048 Conference Condensed Matter Quantum Fields and Strings Quantum Gravity Quantum InformationWe will describe how the reconstruction of a bulk operator can be organised systematically. With a suitable parametrisation, an analogue of the HKLL formula emerges, involving a smearing function satisfying a Klein Gordon equation in the graph. The parametrisation also allows us to read off…
Dynamics for holographic codes
Tobias Osborne - Leibniz University Hannover
PIRSA:17040047 Conference Condensed Matter Quantum Fields and Strings Quantum Foundations Quantum InformationIn this talk I discuss the problem of introducing dynamics for holographic codes. To do this it is necessary to take a continuum limit of the holographic code. As I argue, a convenient kinematical continuum limit space is given by Jones’ semicontinuous limit. Dynamics are then furnished by a unitary…

Random tensor networks and holographic coherent states
Xiaoliang Qi - Stanford University
PIRSA:17040046 Conference Condensed Matter Quantum Fields and Strings Quantum Foundations Quantum InformationTensor network is a constructive description of many-body quantum entangled states starting from few-body building blocks. Random tensor networks provide useful models that naturally incorporate various important features of holographic duality, such as the Ryu-Takayanagi formula for entropy-area…
Abstract quantum theory
Robert Oeckl - Universidad Nacional Autónoma De Mexico (UNAM)
What is the essence of quantum theory? In the present talk I want to approach this question from a particular operationalist perspective. I take advantage of a recent convergence between operational approaches to quantum theory and axiomatic approaches to quantum field theory. Removing anything…
