   Abstract : We study a free quantum scalar field in the BTZ spacetime as a model of the AdS/CFT correspondence for black holes, and show the essential steps in computing Bogolyubov coefficients between modes on either side of the wormhole. As background, we review the BTZ geometry in standard, Kruskal and Poincaré coordinates, holographic renormalisation of the dual field theory and canonical quantisation in curved spacetime.

3. 2. Geometric algebra, conformal geometry and the common curves problem

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Elias Riedel Gårding; [2017]
   Keywords : ;

   Abstract : This bachelor’s thesis gives a thorough introduction to geometric algebra (GA), an overview of conformal geometric algebra (CGA) and an application to the processing of single particle data from cryo-electron microscopy (cryo-EM). The geometric algebra over the vector space Rp;q, i.e. READ MORE
