  1. 1. Gravitational Decoherence in Macroscopic Quantum Systems

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Niklas Engelhardt Önne; [2023]
    Keywords : decoherence; gravitational decoherence; quantum mechanics; quantum physics; macroscopic quantum mechanics; macroscopic quantum physics; gravity; general relativity; gravitational time dilation; quantum-to-classical transition; nonrelativistic quantum mechanics; quantum gravity; dekoherens; gravitationell dekoherens; kvantmekanik; kvantfysik; makroskopisk kvantmekanik; makroskopisk kvantfysik; gravitation; allmän relativitetsteori; gravitationell tidsdilatation; övergången från kvantfysik till klassisk fysik; ickerelativistisk kvantmekanik; kvantgravitation;

    Abstract : The problem of how quantum mechanics gives rise to classicality has been debated for more than a century. A commonly proposed solution is decoherence, i.e. the gradual decay of superpositions in open quantum systems due to their inevitable interaction with their environment. READ MORE

  2. 2. Investigating Tweet Propagation via Dynamical Models and Influencer Analysis

    University essay from Linköpings universitet/Reglerteknik

    Author : Joel Nilsson; [2022]
    Keywords : Social Media Analysis; Dynamical Models; Data Mining;

    Abstract : Social media consume an increasing portion of people’s daily lives and are important platforms in the realms of politics and marketing for reaching out to voters and consumers. Describing and predicting the behaviour of users on social media is thus of interest for companies and politicians, as well as researchers studying information diffusion and human behaviour.

  3. 3. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    University essay from Uppsala universitet/Högenergifysik

    Author : Rohini Sengupta; [2021]
    Keywords : Particle Physics; CERN; Future Circular Collider; FCC-ee; Heavy Neutral Leptons; Long-lived particles; Displaced signatures;

    Abstract : Heavy Neutral Leptons (HNLs) are the heavier counterparts of the light neutrinos of the Standard Model of particle physics. HNLs can simultaneously solve several of the problems the Standard Model cannot yet resolve, one example being that they provide a candidate for Dark Matter. READ MORE

  4. 4. Improving image quality of a streak camera using periodic shadowing

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

    Author : David-Gabriel Lange; [2021]
    Keywords : combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

    Abstract : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. READ MORE

  5. 5. Against Singularity : Modernist housing estates: What went wrong and how can we fix it? Case Study of Norsborg, Botkyrka, Sweden

    University essay from KTH/Urbana och regionala studier

    Author : Andrea Londakova; [2018]
    Keywords : urban design; modernist housing estates; miljonprogrammet; public space; redevelopment; regeneration; transformation; modernism; planning; norsborg; stockholm; sweden;

    Abstract : In my thesis I look into the case of modernist mass housing estates. They appear as a typological, functional and visual anomaly relative to the traditional urban fabric of European urban centers, as a world of its own or a city inside of a city. READ MORE
