  2. 11. Shapes of Spacetimes : Collected tales of black holes

    Author : Emma Jakobsson; Ingemar Bengtsson; Marc Mars; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : In theory, the existence of black holes is predicted by general relativity. In reality, there is a general consensus that they exist in space; in particular at the center of many galaxies. The theory of black holes has been around for decades, but there are still interesting questions calling for attention. READ MORE

  4. 12. Quantum State Analysis : Probability theory as logic in Quantum mechanics

    Author : Anders Månsson; Anders Karlsson; Gunnar Björk; Ingemar Bengtsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum; quantum mechanics; state; state analysis; probability; probability theory; logic; Photonics; Fotonik;

    Abstract : Quantum mechanics is basically a mathematical recipe on how to construct physical models. Historically its origin and main domain of application has been in the microscopic regime, although it strictly seen constitutes a general mathematical framework not limited to this regime.

  5. 13. Information geometries in black hole physics

    Author : Narit Pidokrajt; Ingemar Bengtsson; Jorma Louko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; black holes; thermodynamics; instability; hessian; entropy; ruppeiner geometry; weinhold geometry; information geometry; Theory of relativity; gravitation; Relativitetsteori; gravitation; teoretisk fysik; Theoretical Physics;

    Abstract : In this thesis we aim to develop new perspectives on the statistical mechanics of black holes using an information geometric approach (Ruppeiner and Weinhold geometry). The Ruppeiner metric is defined as a Hessian matrix on a Gibbs surface, and provides a geometric description of thermodynamic systems in equilibrium. READ MORE

  6. 14. Bell tests and the no-signalling assumption

    Author : Massimiliano Smania; Mohamed Bourennane; Ingemar Bengtsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum; quantum optics; Bell tests; CHSH inequality; entanglement; fysik; Physics;

    Abstract : Bell's theorem was originally meant for testing fundamental properties of Nature, namely local realism. However, through the years it has become a powerful device for certifying encryption security, randomness, and entanglement among other properties. READ MORE
