Höga bostadspriser och ekonomiska förutsättningar visar sig som centrala utmaningar för unga vuxna som strävar efter att etablera ett eget hushåll. Trots ett ökat intresse för olika boendelösningar och upplåtelseformer, visar denna studie b

Integer quantum Hall (IQH) states and quantum anomalous Hall (QAH) states show the same static (dc) response but distinct dynamical (ac) response. In particular, the ac anomalous Hall conductivity profile $\sigma_{yx}(\omega)$ is sensitive to the ban

We investigate the optical activity of tilted nodal loop semimetals. We calculate the full conductivity matrix for a band structure containing a nodal loop with possible tilt in the $x-y$ plane, which allows us to study the Kerr rotation and elliptic

We study two-dimensional electron systems in the hydrodynamic regime. We show that a geometrical Berry curvature modifies the effective Navier-Stokes equation for viscous electron flow in topological materials. For small electric fields, the Hall cur

Topologically protected qubits based on nanostructures hosting Majorana bound states (MBSs) hold great promise for fault-tolerant quantum computing. We study the transport properties of nanowire networks hosting MBSs with a focus on the effects of th

The field of obstacle avoidance is a well-researched area. Despite this, research on obstacle avoidance in three dimensions is surprisingly sparse. For platforms which are able to navigate three-dimensional space, such as multirotor UAVs, such method

This thesis examines the effects of electricity visualization in an office building. The subject was investigated through the creation of a web based visualization tool that was made accessible to the about 1500 employees in a large office building.

Two implementations of the backtracking algorithm for solving Sudoku puzzles as well as their dependence on the representations of the problem have been studied in order to ascertain pros and cons of different approaches. For each backtracking step,

Auto Deco Primer Valve är ett projekt som har resulterat i ett förenklat startsystem för tvåtaktsmotorer. Att starta en tvåtakts motor med dragsnöre är både tidskrävande och jobbigt, därför vill projektgruppen ge samhället en lösning på
