1. 1. Cosmological Horizons and the Unruh Effect

   L3-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Niklas Engelhardt Önne; [2023]
   Nyckelord :Unruh effect; quantum scalar fields; Bogoliubov transformations; accelerated observers; Minkowski spacetime; cosmological horizons; Rindler observers; special relativity; QFT; Unruh-effekten; skalära kvantfält; Bogoliubov-transformationer; accelererande referenssystem; Minkowski rumtid; kosmologiska horisonter; Rindlerobservatörer; speciell relativitetsteori; QFT;

   Sammanfattning : The black hole information paradox, which states that the evaporation of black holes due to Hawking radiation results in a violation of the conservation of quantum information, is arguably one of the most fundamental problems in all of modern physics. Through the equivalence principle, the essence of the problem can be understood and studied in the context of much simpler flat spacetime (described by the theory of special relativity); in this context the Hawking radiation takes the form of the so-called Unruh effect, a thermal effect in the vacuum of a Minkowski quantum field theory that can be measured by accelerated observers.

3. 2. Spatiotemporal Consciousness in Special Relativity

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

   Författare :Gustaf Malmberg; [2023]
   Nyckelord :Consciousness; Phenomenology; Special Relativity; Relativistic Spacetime; Theoretical Physics;

   Sammanfattning : The experience of time passing is a fundamental part of the human experience, but what is the relationship between conscious experiences in time and the relativistic nature of space and time? It is natural to think that our phenomenal experiences are realised by neuralevents in our brains. And it seems plausible that the order of these neural events makes a difference to our phenomenology. LÄS MER

4. 3. Speciell relativitetsteori i gymnasieskolan

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikundervisningens didaktik

   Författare :Vendla Niklasson; [2022]
   Nyckelord :speciell relativitetsteori; fysikdidaktik; einsteins tåg; gymnasieskolan; tvillingparadoxen;

   Sammanfattning : Special relativity is a subject that attracts interest among students, but there are many things that make students experience it as difficult. As a physics teacher, it is important to both have a solid base of knowledge in physics as well as educational knowledge within the subject. LÄS MER

5. 4. Black Holes and Scalar Fields : A study of a massive scalar field around a black hole

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Abdulmasih Ghazal; [2022]
   Nyckelord :Black holes; scalar field; General relativity; special relativity; spacetime; cosmology; Schwarzschild; Schrödinger equation; Svart hål; relativitetsteori; skalär fält; rumtid; Shrödinger; Schwarzschild.;

   Sammanfattning : Black holes are one of the most interesting objects in the universe, and studying these objects should give exciting results. This research will investigate the General Theory of Relativity, explaining the essence of the theory needed for deriving solutions for a Schwarzschild black hole. LÄS MER

7. 5. The Scattering matrix : Properties and one-dimensional examples

   Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Samuel Clarito; [2022]
   Nyckelord :;

   Sammanfattning : The scattering matrix is used to relate particle states before and after undergoing a scattering process. It is used in quantum mechanics, scattering theory and quantum field theory. When quantum theory got developed, the classical descriptions for scattering were no longer sufficient and other methods began to develop. LÄS MER
