8. Effects of non-linear excitation on the propagation of light

Presentation

With the increasing number of nuclear-resonant photons per pulse at x-ray free electron lasers (XFELs), achieving higher excitation levels experimentally becomes feasible. This development makes it particularly compelling to investigate light propagation and dynamics beyond the low-excitation regime (LER) and around population inversion. Thus, in my thesis, we examined the time response of...

3. Exploring nematic behaviour in systems with polar symmetry.

Presentation

Active matter encompasses a wide range of systems, from bird-flocks to bacterial colonies. Two main formalisms describe these systems based on individual particle symmetries: polar and nematic. Each formalism leads to unique behaviours, the most significant being the appearance of half and full integer topological defects for nematic and polar respectively. However, recent advances in the...

9. Gravitational waves lensing by the strong field of a black hole

Presentation

The first detection of gravitational waves (GWs) in 2015 opened the door to GW physics, which has allowed us to test Gravity with unprecedented precision.

When emitted by a source, usually a merging binary of compact objects such as black holes (BHs), gravitational waves propagate moslty unaltered through the cosmos. However, if they encounter objects in their path that are massive/compact...

1. Quantifying the Reduction in Carbon Footprint of Physics-Informed Machine Learning in the Pursuit of Greener Artificial Intelligence Practices

Presentation

This thesis explores the potential reduction in the carbon footprint of machine learning (ML) models by integrating physical constraints into their design. Traditional ML models rely on large datasets and extensive parameter optimization, leading to significant computational costs and associated carbon dioxide (CO₂) emissions. However, by adopting a physics-informed approach, it may be...
