Entanglement features of random neural network quantum states
Neural networks offer a novel approach to represent wave functions for solving quantum many-body problems. But what kinds of quantum states are efficiently represented by neural networks? In this talk...

An operator-algebraic formulation of self-testing
We give a new definition of self-testing for correlations in terms of states on C*-algebras. We show that this definition is equivalent to the standard definition for any class of...

The Complexity and (Un)Computability of Quantum Phase Transitions
The phase diagram of a material is of central importance in describing the properties and behaviour of a condensed matter system. Indeed, the study of quantum phase transitions has formed...

Anakin's story from Star Wars soundtracks
We shall explore the genius of John Williams when it comes to tell stories through his soundtracks. Since the full analysis of Anakin’s life is still a work in progress...

Holographic scattering from quantum error-correction
We revisit the problem of how interactions emerge in quantum gravity. Namely, we show that bulk scattering of multiple particles in the AdS space requires multipartite entanglement on the boundary...

Quantum complexity, irreversibility, learnability and fluctuations.
Quantum complexity is a notion characterizing the universality of the entanglement arising from a quantum evolution. A universal evolution will result in a complex entanglement. At the same time, this...

The Einstein Toolkit
One of the best known open-source tools for studying numerical relativity is the Einstein Toolkit. With it, you can simulate collisions of black holes and neutron stars, and study their...

Symmetries, Duality, and the Unity of Physics
Global symmetries and gauge symmetries have played a crucial role in physics. The idea of duality demonstrates that gauge symmetries can be emergent and might not be fundamental. During the...

Logarithmic Sobolev Inequalities for Quantum Many-Body Systems.
The mixing time of Markovian dissipative evolutions of open quantum many-body systems can be bounded using optimal constants of certain quantum functional inequalities, such as the logarithmic Sobolev constant. For...
