1. Laboratory starlight simulator for future space-based heterodyne interferometry
University essay from Luleå tekniska universitet/RymdteknikAbstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

2. 2 + 1 Dimensional Chern-Simons Theory for Landau-Ginzburg Theory
University essay fromAbstract : In this work, 2 + 1 dimensional Chern-Simons theory have been used in an attempt to describe superconductivity. It was examined if the two defining properties of superconductivity, infinite direct current (DC) conductivity and the Meissner effect, as well as the two characteristic length scales of superconductors, the London penetration depth and the coherence length, could be obtained.

3. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska HögskolaAbstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

4. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
University essay from KTH/Tillämpad fysikAbstract : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. READ MORE

5. Tabletop Role-playing Games (TRPG) and Group Coherence
University essay from Södertörns högskola/MedieteknikAbstract : Tabletop role-playing games (TRPGs), also known as Pen-and-Paper role-playing games(PnP-RPGs), are games that can be described as a mix between board games and improvisationaltheatre. Each player takes on the role of a single character, while the game’s leader(GM or DM) is in charge of both simulating the game world, acting out all remainingcharacters and facilitating the game rules.
