Axion-like particles can form clouds around rotating supermassive black holes through superradiant instability. Via axion-photon coupling, these clouds can imprint time-dependent oscillations on the observed electric vector position angle. I will present constraints on such clouds around M87* and…

The regularisation of entanglement entropy is integral to the possibility of it sourcing the Bekenstein-Hawking entropy. This regularisation ought to come from quantum gravity, which if covariant, can induce a regularisation scheme inapplicable directly on hypersurfaces, but instead suited to…

Modern physics is built upon three fundamental frameworks: quantum theory, general relativity, and information theory. In this talk, I will first introduce the field of relativistic quantum information, an operational framework that studies quantum information in relativistic settings by bringing…

Deformation quantization is a mathematical approach to understanding the quantization of classical mechanical systems. This talk will outline the procedure of deformation quantization and how it connects to the mathematical study of deformation theory. Time permitting, we will discuss some examples…

As a continuation of the canonical formulation of Loop Quantum Gravity, I will present an introduction to its covariant, path‑integral formulation in terms of spinfoams. Starting from the interpretation of spin networks as quantum states of geometry, I will explain how spinfoams arise as histories…

Formulations of gravity as a constrained topological theory not only help us understand its variables and symmetries, but also are especially useful for quantization. In the first part of this talk, I will present the EPRL (Engle-Pereira-Rovelli-Livine) model, which is a spinfoam quantization of the…

As part of deepening my background in Loop Quantum Gravity, I will give a brief introduction to the canonical formulation of the theory. I will outline the motivation for choosing appropriate classical variables—specifically the Ashtekar–Barbero connection and densitized triad—and explain how these…

In this broad-audience talk, I will discuss the basics of gravitational wave theory and the major achievements in the field following the direct observation of the first gravitational wave signal in 2015. Then, I will discuss how gravitational wave data are used to test the validity of general…

This panel discussion brings together researchers to share insights on effective scholarly writing. Each panelist will highlight two well-written papers: one of their own and one by other authors. Through moderated questions and open audience discussion, panelists will discuss what makes these…

This talk will be a brief and interactive introduction to my current research and the cosmological concepts that go along with it. I will assume limited prior knowledge of GR and cosmology so that even students in unrelated fields can learn something interesting.

When dealing with QFTs or with quantum mechanical systems in the thermodynamic limit, one encounters uncountable Hilbert spaces. These are mathematically wilder and physically less realistic than their countable counterparts. In this talk, we will explore how vacua encode a choice to reduce the…
