Signatures of phase transition in binary neutron star mergers
(2025)Binary neutron star (BNS) mergers are a promising testing ground for warm highly dense states of matter. During a binary merger, densities are expected to easily exceed the nuclear saturation density. This invites the ... -
The Role of Matter Loops and Kinetic Mixing in Higgs Portal Inflation
(2025)Cosmological inflation has emerged as a cornerstone of modern cosmology because it elegantly accounts for the Universe’s large scale homogeneity, flatness and the nearly scale invariant spectrum of primordial fluctuations, ... -
Beyond the horizon
(2025)This paper investigates holographic reconstructions of black hole interiors. It begins by presenting the historical evolution of the black hole information paradox, highlighting the main challenges in achieving a coherent ... -
Cosmological Perturbations Induced by Ultralight Scalar Dark Matter: A Quantum Field Theoretic Perspective.
(2025)The inhomogeneities in the early universe grow during the matter-dominated era, eventually giving rise to the large-scale structures we observe today. This growth is primarily driven by dark matter, which, at the onset ... -
The influence of bioturbation on geochemical cycles at Blakeney salt marsh, Norfolk: an analysis using lipid biomarkers
(2025)A redox dichotomy is seen in the pond sediments of the salt marshes in East Anglia, Norfolk, U.K. At Blakeney salt marsh, ponds contain two sediment types: bioturbated sediments are iron-rich and contain burrowing organisms, ... -
Soliton solutions for the electron flow in graphene.
(2025)In the past decades, graphene is a material of great interest. Due to its purity, electrons can move through the lattice with very low resistance. Therefore the well known Navier Stokes equations can be applied to model ... -
Probabilistic Path Integrals in Quantum and Statistical Physics
(2025)In this thesis, we explore the mathematical techniques for rigorously constructing path integral measures in quantum mechanics, statistical field theory, and relativistic quantum field theory. We begin with the quantum ... -
Mutual information in deformed conformal field theories
(2025)The operator product expansion of twist operators within the replica trick framework has become a central tool for computing entanglement entropies in conformal field theories. Recent advances have successfully applied ... -
Potentiodynamic Microscopy Of Battery Materials
(2025)This thesis presents the development and application of a custom-built electro modulation optical microscope for operando monitoring of lithium battery material charging and discharging processes, contributing to the goals ... -
Ends of topoi
(2025) -
Suspension of operads
(2025)We study the suspension of operads, specifically in the ∞-categories of spectra and pointed spaces, arising in the literature in the context of Koszul duality. In the stable case, we investigate a conjectured characterising ... -
Étale Homotopy Theory
(2025)In this thesis the étale homotopy type of a scheme is constructed, using modern higher category theory and shape theory. This is an invariant of a scheme. This then is compared to the orginal definition from the 60's and ... -
The Sum of Reciprocals of Divisors of Lucas Sequences
(2025)In this thesis we extend results on reciprocal sums of divisors of Lucas sequences due to Pollack, Engberg and Agrawal to results that are similar in spirit for reciprocal sums of divisors of companion Lucas sequences. ... -
Waterproof for Bewijzen in de Wiskunde
(2025)Waterproof is a proof assistant developped at Eindhoven University of Technology. It is used to teach students at Analysis I, how to proof mathematical statements. Waterproof will be implemented at the Bachelors course ... -
Accelerometry data as a potential tool to help understand rare diseases
(2025)The Wilhelmina Children’s Hospital (WKZ) provides care for a wide range of patients, including some with ultra rare diseases. Using as much data as possible is essential in treatment of such conditions. This exploratory ... -
On the equivariant Whitehead towers of BO and BU.
(2025)The main focus of this research project will be constructing and studying the structure of the Whitehead towers for the classifying spaces of the stable orthogonal and unitary groups denoted by BO and BU respectively. Given ... -
Gromov–Witten Invariants, Topological Strings and Mirror Symmetry
(2025)Gromov–Witten invariants count the number of holomorphic maps into some pro-jective variety. We introduce moduli stacks and follow Kontsevich’s construction of Gromov–Witten invariants by doing a Deligne–Mumford compactification ... -
Automatic Rodent Detection from Motion-triggered Wildlife Cameras
(2025)Active monitoring is indispensable in containing the spread of contagious diseases among animal stocks, particularly in detecting any intruders that may introduce harmful pathogens into livestock farms. Given the time-consuming ... -
Exploring the Influence of Synthetic Training Data Diversity on the Behavior of Fine-Tuned Large Language Models
(2025)In recent years, large language models (LLMs) have become an extremely popular and active subdiscipline of artificial intelligence (AI). As LLMs become more capable, they are increasingly being used to generate data for ...
