10. Improving Neutrino Oscillation Measurements by using the Earth’s layer structure

31/03/2023, 13:00

Presentation

One persisting question of the Standard Model and particle physics is the Neutrino Mass Ordering. Even though we know that neutrinos have masses, we do not know how these masses are ordered from lowest to highest. Because of the quantum-mechanical nature of neutrinos and their reluctance to interact, measurements of their properties are difficult and convoluted. I will show how the earth’s...

6. Exploring Demographic Drift: A Redshift Dependent Two-Population Model of Type Ia Supernovae and Its Implications for Dark Energy

31/03/2023, 13:20

Presentation

Type Ia supernovae have played a significant role in measuring the acceleration of the Universe's expansion and the existence of dark energy. However, understanding the nature of the supernovae and the impact of population, originating from two distinct progenitor channels (single- and double-degenerate), changes over cosmic time is crucial to accurately measuring these phenomena. In this...

3. Effective bond theory for frustrated magnets

31/03/2023, 13:40

Presentation

Frustrated magnets are a class of materials where competing interactions between magnetic moments leads to complex behavior. As this complex behavior emerges from relatively simple rules, studying these materials can give us insight into how competing interactions can lead to the plethora of phenomena we see in strongly correlated materials, as well as insight into the nature of magnetic...

5. Structural properties of kagome-layered crystals

31/03/2023, 14:20

Presentation

Recently, a family of kagome metals, AV3Sb5, has been synthesized and found to display superconductivity at low temperatures. Before the onset of superconductivity, a new phase appears at which the material seems to undergo a structural transition which causes the unit cell to double in size. Evidence has been found suggesting that this phase transition is not just a normal structural...

18. Classifying the first large clean neutrino sample in real data from the IceCube Neutrino Observatory using a Graph Neural Network

31/03/2023, 14:40

Presentation

The IceCube Neutrino Observatory (IceCube) uses a cubic kilometre of the Antarctic ice sheet to detect neutrinos. IceCube carries out neutrino oscillation measurements using atmospheric neutrinos. Furthermore, it contributes to multi-messenger astronomy, searching for the extragalactic origins of neutrinos. All this interesting research relies on accurate neutrino classification and...

1. Spectral Integrability In Twisted N = 4 Super Yang-Mills Theory

31/03/2023, 15:00

Presentation

$\mathcal{N}=4$ Super Yang-Mills theory has been hailed as the "hydrogen atom of the 21st century", owing to it's similarity to Quantum Chromodynamics (QCD) albeit with much larger symmetry allowing for simplification of otherwise extremely difficult computations.
The model is believed to be "Integrable", meaning that it is well behaved and solveable to all orders in pertubation theory,...

13. Mechanisms behind Induced Polarization Effects in Water and Brines Confined in Clay Minerals Oriented Films

31/03/2023, 15:20

Presentation

The dynamic behavior of water molecules in soils has been extensively studied throughout the years and the understanding of the diffusion processes that occur are of primary importance especially when it comes to waste manage- ment. The main goal of this master project is to study how water molecules confined in clay minerals are moving regarding to salinity and how an electric field...
