  1. 1. Gravity Illustrated. Spacetime Edition

    Författare :Rickard Jonsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; embeddings; pedagogical techniques; curved spacetime; optical geometry; gyroscope precession; inertial forces;

    Sammanfattning : This thesis deals with essentially four different topics within general relativity: pedagogical techniques for illustrating curved spacetime, inertial forces, gyroscope precession and optical geometry. Concerning the pedagogical techniques, I investigate two distinctly different methods, the dual and the absolute method. LÄS MER

  4. 3. Seven Senses of the City : Urban Spacetime and Sensory Memory in Contemporary Sinophone Fiction

    Författare :Astrid Møller-Olsen; Kinesiska; []
    Nyckelord :HUMANIORA; HUMANITIES; literary sensory studies; sensory studies; urban fiction; senses; Sinophone fiction; comparative literature; Chinese literature; Taipei; Hong Kong; Shanghai; literary studies; spacetime; spatiality; narratology; rhythmanalysis;

    Sammanfattning : The objective of this dissertation is to investigate the narrative mechanisms and imagery that fictional works employ to conceptualize and communicate complex human experiences of space, time and memory. Furthermore, this study shows how contemporary cities change the way we think about such basic concepts by analyzing narratives that employ and encourage multisensory, spatiotemporal understandings of reality characterized by permeable boundaries between the material, social and imaginary domains.

  5. 4. Emergent spacetime from simple field theories

    Författare :Julius Engelsöy; Bo Sundborg; Sumit R. Das; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AdS CFT; thermalization; quench; large N singlet models; emergent spacetime; fysik; Physics;

    Sammanfattning : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. LÄS MER

  7. 5. Multipole Moments of Stationary Spacetimes

    Författare :Thomas Bäckdahl; Magnus Herberthson; Brien Nolan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multipole moments; stationary; static; relativistic; spacetime; convergence; specified; Mathematical physics; Matematisk fysik;

    Sammanfattning : In this thesis we study the relativistic multipole moments for stationary asymptotically flat spacetimes as introduced by Geroch and Hansen. These multipole moments give an asymptotic description of the gravitational field in a coordinate independent way. LÄS MER
