1. Development of a guide system for free neutron oscillation searches at the European Spallation Source
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS ABAbstract : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

2. Quantum Espionage
University essay from KTH/Tillämpad fysikAbstract : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. READ MORE

3. Photoluminescence Mapping of Erbium Doped Lithium Niobate
University essay from KTH/Tillämpad fysikAbstract : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

4. Learning in physics with simulation : Students’ needs & perceptions of the interaction with Algodoo, and learning in physics
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Initiatives to implement computational thinking and science, technology, engineering & modelling into learning processes have been taken by many authorities worldwide, and in Sweden as well. The Swedish government made changes in the high school curriculum in order to develop student’s digital competence including programming which has been in force since June 2018 (Skolverket, 2018).

5. Properties of the Optical Hot Spots in the Circumstellar Ring of SN 1987A
University essay from KTH/FysikAbstract : The proximity of Supernova 1987A provides a great opportunity to study the aftermath of the impact of the ejecta with the dense clumps (observed as ”hot spots”) located in the equatorial circumstellar ring. This thesis examines the properties of the clumps by using Hubble Space Telescope optical imaging taken with the F625W and F675W broad filters between 1994 and 2022. READ MORE
