1. 1. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?

   Master-uppsats, Uppsala universitet/Materialteori

   Författare :Karl Herlin; [2023]
   Nyckelord :quantum mechanics; quantum physics; philosophy of physics; interpretation of quantum mechanics; measurement problem; problem of preferred basis; problem of non-observability of interference; problem of definite outcomes; environment induced superselection rules; copenhagen interpretation; decoherence; irreducibility of classical concepts;

   Sammanfattning : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. LÄS MER

3. 2. On quantum systems and the measurement problem

   Master-uppsats, Stockholms universitet/Fysikum

   Författare :Nicolas Boulle; [2023]
   Nyckelord :Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

   Sammanfattning : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. LÄS MER

4. 3. Vägen från europeisk klimatlag till nationell lagstiftning och genomförandestrategier : En jämförelse av svensk och dansk lagstiftning i relation till byggsektorn

   Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

   Författare :Malin Garhem; Cecilia Grip; [2023]
   Nyckelord :Malmo; Copenhagen; Øresund; Climate law; Construction sector; Implementation strategy; Grounded theory; Malmö; Köpenhamn; Öresund; Klimatlag; Byggsektorn; Genomförandestrategi; Grundad teori;

   Sammanfattning : Växthusgasutsläpp är den främsta bidragande faktorn till dagens klimatförändringar och byggsektorn bidrar med nästan en tredjedel av dem. Att reducera utsläppen för att uppnå klimatmålen om klimatneutralitet 2050 är en utmaning för miljölagstiftningen. LÄS MER

5. 4. TikTok Risk or Threat? Competing narratives about risk and threats in the US case

   Master-uppsats, Umeå universitet/Statsvetenskapliga institutionen

   Författare :Stephanie Scatton; [2023]
   Nyckelord :TikTok; USA; social media; securitization; riskification; case study; risk; threat; content analysis.;

   Sammanfattning : TikTok a Chinese-based social media application, in the last five years has reached global success. It became the first non-American application to reach such massive popularity. This has sparked controversy in the US. Recent studies have highlighted the benefits and disadvantages of this social media app. LÄS MER

7. 5. A Current Need for Continuity

   Magister-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

   Författare :Nils Patrik Svensson; [2022]
   Nyckelord :agential realism; Karen Barad; new materialism; math; infinitesimals; complexity; quantum physics; Copenhagen interpretation; phenomenology; Merleau-Ponty; continuity; Rawls; binary;

   Sammanfattning : Throughout these last few decades, phenomenology and modern physics have slowly started to approach each other in order to bridge the gap between the subjective and objective. In this thesis I aim to show an approach done with the help of Karen Barad's agential realism; a quantum interpretation enabling us to better understand and analyse our complex world, as well as our perception of it.
