Ashley Milsted

Emergent conformal transformations in critical spin chains and
tensor networks

Conformal symmetry emerges in many critical systems. It turns out, conformal *transformations* do too! Also inside some tensor networks.

Paula Mellado

Of honeycomb lattices: classical and quantum spin liquids

TBA

Djordje Radicevic

Dualities, anomalies, and all that

I will describe some ideas from my recent work that centers on dualities, anomalies, and spin structuredependence in lowdimensional fermion theories.

Aleksander Kubica

Cellularautomata decoders with provable thresholds for topological codes

I will discuss a new cellular automaton, the Sweep Rule, which generalizes Toom's rule and can be used to decode errors in topological quantum codes in d ≥ 3 dimensions.

Stefan Kuehn

Approaching Lattice Field Theories with Tensor Networks

I will talk about the challenges and prospects of using tensor networks to numerically study lattice field theories. While the dimensions and systems sizes amenable to tensor network studies are still far from those achieved by conventional Monte Carlo simulations, they offer a promising alternative for scenarios in which Monte Carlo simulations are hindered by the sign problem.

Andres Schlief Carvajal

NonFermi Liquid Metals

I will give a brief overview of my contributions to the understanding of NonFermi Liquid metallic states of matter, my current research and future directions.

Guifre Vidal

Tensor networks and geometry

For the last 10 years MERA has been debated to represent either "hyperbolic space" or "de Sitter spacetime". I will show that it actually corresponds to a path integral on a "light cone", which is neither of those, and how to build euclidean MERA and lorentzian MERA tensor networks that correspond to hyperbolic space and de Sitter spacetime, respectively.

Janet Hung

Tensor network and bulk reconstruction

We describe a few things that we learn about reconstructing the AdS/CFT using tensor networks

SungSik Lee

State dependent spread of entanglement in relatively local Hamiltonians

Understanding dynamical properties of a class of nonlocal Hamiltonians from which local theories emerge within shortrange entangled states.

Jacob Bridgeman

Defects in Topological Phases

I will discuss recent work (with Daniel Barter and Corey Jones) on fusing line and point defects in topological phases (arXiv:1806.01279 and arXiv:1810.09469).

Nick Hunter Jones

Quantum information approaches to chaos and scrambling

Quantum chaos is believed to underlie the dynamics of generic stronglyinteracting systems, but we are still without precise definitions. I'll describe some QI inspired diagnostics of chaotic dynamics.

Roger Melko

How I learned to stop worrying and love the pickle

TBA

Alvaro M. Alhambra

Quantum equilibration in finite time

I will outline previous rigorous results on equilibration and thermalization of quantum systems, sketch the big open problems in the area and show results on the linear response regime

Adam Lewis

Matrix Product State Simulations of StressEnergy Tensors Near 2D Black Holes

We discuss methods to compute the stressenergy tensor near black holes using matrix product states

Martin Ganahl

continuous MPS and continuous MERA: how I mastered the Fourier transform

I will talk about continuous matrix product states and continuous multiscale entanglement renormalization for nonrelativistic and relativistic quantum field theories

Chong Wang

Effective field theory approach to quantum manybody physics

Manybody physics is hard. Fortunately the universal aspects of the physics (say at low energy, long wavelength) of a manybody system are often captured by a much simpler quantum field theory. I will briefly describe some examples in quantum magnetism along this line, focusing on recent progress such as dualities, emergent symmetries, anomalies and UVIR connections.

Yoni BenTov

Thermodynamic interpretation of gravitational shockwaves

I want to understand whether the ‘t Hooft effective action can be derived from geometrical perturbations of the bifurcation surface.

Antony Speranza

Edge modes and entanglement for gravity

I will discuss the problem of defining entanglement entropy in a gravitational theory, and the necessity of introducing edge modes in a subregion to allow the gravitational Hilbert space to factorize. I will comment on some some confusing aspects of this program related to edge modes for diffeomorphisms that move the entangling surface.

Vasudev Shyam

The flow and finite radius holography

I will describe the role of irrelevant deformations such as the operator in holographic theories whose bulk duals are described by gravity regions of AdS space cutoff at finite radius. I will also describe how certain holographic entropy conjectures generalise in this scenario.
