3. Analyzing Neutron Scattering Data on the Excitations in the Spin 1 Haldane System NENP

Poster

A 1D chain of antiferromagnetic spin systems is a critical topic in quantum many-body physics. Theory has predicted that different spins (S) would result in different behaviors. Here, I will focus on the excitations of the Spin 1 Haldane system in the ground state.

In the S=1 system, both experiments and theories indicate that the ground state is topological and that there is a spin gap,...

13. Full Spectrum Modeling in AGN Galaxies Using Penalized Pixel-Fitting

14/06/2024, 15:30

Progress poster

The goal is to create BPT diagrams for nearby Active Galactic Nuclei (AGN). These diagrams, named after Baldwin, Phillips, and Telervich, are a set of nebular emission line diagrams used to distinguish the ionization mechanism of nebular gas. Using these we can map the gas on a large scale within galaxies and identify regions where we have AGN feedback, and help us understand AGNs’ role in the...

10. Investigating physical parameters of protostellar systems

14/06/2024, 15:30

Poster

Over the recent years our ability to model and observe young stars has increased dramatically, enabling the compilation of large catalogues of observed and in silico protostars. We have learned that accretion discs form immediately when a star is born, and that the first planets may form already while the star is still embedded inside a large, cold, and dusty envelope during the first million...

6. SALSA Virtual A virtual neutron scattering instrument

14/06/2024, 15:30

Poster

In this work, we present a digital twin of the stress imaging neutron
scattering instrument SALSA. This digital twin aims to correctly predict
SALSAs neutron beam characteristics at sample position. This twin was
made, by implementing a bent perfect crystal monochromator in the soft-
ware package McStas, and then used McStas to recreate the instrument
setup of SALSA. we then performed...

7. Sub-GeV Dark Matter and Proton Interaction in the Active Galactic Nucleus NGC 1068.

14/06/2024, 15:30

Poster

Observations of high-energy neutrinos from the active galactic nucleus NGC 1068 suggest the acceleration of cosmic rays in the vicinity of the central supermassive black hole (corona) [1]. These high-energy cosmic-rays can collide either with gas or with photon fields, producing charged and neutral pions. The decay of neutral pions leads to a gamma-ray flux, which in other sources has been...

12. Topological Data Analysis of Phase Transitions in Soft Active Matter Systems

14/06/2024, 15:30

Progress poster

This thesis explores the application of algebraic topological methods, particularly persistent homology, in the analysis of models within statistical, condensed matter, and active matter systems. The primary goal is to classify phase transitions in soft active matter systems characterized by topological defects. Building on preliminary studies using the XY-model as a reference, we propose to...
