Conformal Geometry of Null Infinity, including gravitational waves
Since the seminal work of Penrose, it has been understood that conformal compactifications (or "asymptotic simplicity") is the geometrical framework underlying Bondi-Sachs' description of asymptotically flat space-times as an asymptotic...

On the classification of topological phases
There is a rich interplay between higher algebra (category theory, algebraic topology) and condensed matter. I will describe recent mathematical results in the classification of gapped topological phases of matter...

Reinforcement Learning assisted Quantum Optimization
We propose a reinforcement learning (RL) scheme for feedback quantum control within the quantum approximate optimization algorithm (QAOA). QAOA requires a variational minimization for states constructed by applying a sequence...

Light Hidden Sectors and the Hubble Tension
The inference of the present expansion rate from the Cosmic Microwave Background and other early-time probes (assuming standard cosmology) is in significant tension with several direct measurements of the same...

Engineering and measuring higher-order topology
Recently, a lot of attention has been dedicated to a novel class of topological systems, called higher-order topological insulators (TIs). The reason is that, while a conventional d-dimensional TI exhibits...

COVID-19: Detecting the Dark Matter of the Disease
COVID-19 is a mysterious disease associated with a large number of unanswered questions. In this talk we review what is currently known, what is still a mystery and highlight some...

Emergent criticality in non-unitary random dynamics
In this talk, I will discuss emergent criticality in non-unitary random quantum dynamics. More specifically, I will focus on a class of free fermion random circuit models in one spatial...
