First-principle approach to the superpositions of gravitational fields in atom interferometry
Understanding the fundamental nature of gravity at the interface with quantum theory is a major open question in theoretical physics. Recent progress in experiments has enabled probing the interaction of...

Causality and Ideal Measurements of Smeared Fields in Quantum Field Theory
The usual quantum mechanical description of measurements, unitary kicks, and other local operations has the potential to produce pathological causality violations in the relativistic setting of quantum field theory (QFT)...

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...

Toys can't play: physical agents in Spekkens' theory
Information is physical, and for a physical theory to be universal, it should model observers as physical systems, with concrete memories where they store the information acquired through experiments and...

Phenomenological thermodynamics with multiple quantities of interest
Joint work (in progress) with Ladina Hausmann, Nuriya Nurgalieva and Renato Renner We can classify contemporary approaches to thermodynamics in roughly four camps: (1) Top-down microscopic approaches. These are for...

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...

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...
