1. 1. Object shape and depth perception in VR

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : David Persson; Kristi Francis; [2023]
   Keywords : virtual reality; depth perception; minimally invasive neurosurgery;

   Abstract : Virtual reality (VR) for surgical training shows promise in preparing surgeons for complex procedures. However, achieving a high level of realism in VR is essential for the skills acquired to translate effectively into real-world applications. READ MORE

3. 2. Cosmological Horizons and the Unruh Effect

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Niklas Engelhardt Önne; [2023]
   Keywords : 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;

   Abstract : 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.

4. 3. MadGraph Implementations of the Chirality-Flow Formalism for QED

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Emil Boman; [2023]
   Keywords : Physics and Astronomy;

   Abstract : The chirality-flow formalism has been proven to simplify the calculation of helicity amplitudes, both analytically and in a first numerical implementation developed as an extension of MadGraph5_aMC@NLO. Expanding on this work, two new implementations have been developed. READ MORE

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

   University essay from Uppsala universitet/Teoretisk fysik

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

   Abstract : 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. READ MORE

6. 5. Matter-streams as sources of the Kerr metric

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Julian Boy; [2022]
   Keywords : General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

   Abstract : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. READ MORE
