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.

Djordje Radicevic
|
Dualities, anomalies, and all that
|
I will describe some ideas from my recent work that centers on dualities, anomalies, and spin structure-dependence in low-dimensional fermion theories.
|
Aleksander Kubica
|
Cellular-automata 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
|
Non-Fermi Liquid Metals
|
I will give a brief overview of my contributions to the understanding of Non-Fermi 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
|
Sung-Sik Lee
|
State dependent spread of entanglement in relatively local Hamiltonians
|
Understanding dynamical properties of a class of non-local Hamiltonians from which local theories emerge within short-range 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 strongly-interacting 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 Stress-Energy Tensors Near 2D Black Holes
|
We discuss methods to compute the stress-energy 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 multi-scale entanglement renormalization for non-relativistic and relativistic quantum field theories
|
Chong Wang
|
Effective field theory approach to quantum many-body physics
|
Many-body physics is hard. Fortunately the universal aspects of the physics (say at low energy, long wavelength) of a many-body 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 UV-IR 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.
