  1. 11. Higher Forms and Dimensional Hierarchy in Topological Condensed Matter

    University essay from KTH/Fysik

    Author : Yashar Honarmandi; [2022]
    Keywords : Theoretical physics; topological quantum matter; parametrized systems; Berry phase; higher Berry curvature; effective field theory; topological action; topological insulators; dimensional hierarchy; Teoretisk fysik; topologisk kvantmateria; parametriserade system; Berryfas; högre Berrykrökning; effektiv fältteori; topologisk verkan; topologiska isolatorer; dimensionshierarki;

    Abstract : This report discusses higher differential forms with applications in the study of topological phenomena. The integer quantum Hall effect is first discussed, demonstrating a connection between models on a lattice and quantum field theories bridged by a topological invariant, namely the Chern number.

  3. 12. Impact of Lecture Hall Layout on Evacuations Using Crowd Simulations

    University essay from KTH/Datavetenskap

    Author : Tobias Mattsson; Ernest Umeh; [2022]
    Keywords : Lecture hall; Evacuation; Simulation; Evacuation rate; Layout variation; Föreläsningssal; Evakuering; Simulation; Evakueringstakt; Layoutvariationer;

    Abstract : The planning and preparation phases of emergency management are of great social interest. If appropriate safety measures can be implemented in buildings beforehand as a response to foreseeable hazards, the safety of individuals can be significantly increased. READ MORE

  4. 13. Skolgårdsgestaltningen påverkar användningen : gröna kvaliteter stärker ungdomars rätt till lek och vila

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Rut Lindeberg; [2021]
    Keywords : landskapsarkitektur; ungdomar; skolgårdsgestaltning; barnkonventionen; gröna kvaliteter;

    Abstract : Kring ungdomars skolgårdar finns en osäkerhet, målgruppen räknas som barn samtidigt som de närmar sig vuxen ålder. FNs Barnkonvention blev 2020 svensk lag vilket ger ungdomar rätt till lek och vila, under pauser från skolarbetet. Skollagen ger dock inget uttalat stöd för en skolgård utan fokuserar på målstyrda kunskapskrav. READ MORE

  5. 14. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

  6. 15. Automatic Torque Control for Bicycle Driven Brushless DC (BLDC) Generator

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Luke Müller; Kasper Sjöström; [2021]
    Keywords : BLDC; brushless dc generator; brushless dc motor; JFET; Torque; Generator Torque; Automatic Torque Control; Field Effect Transistor; PWM;

    Abstract : This work was carried out on behalf of Science Safari. Science Safari wants to create a product that facilitates the understanding of how much physical work is required to create electrical energy. This is done by cranking the pedals of a bicycle. READ MORE
