4. 2. The Quest for M-theory

   Author : Ulf Gran; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; solitons; gauge symmetry; M-theory; string theory; duality; p-branes; D-branes; superspace; supergravity;

   Abstract : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. READ MORE

5. 3. Linear response theory: from black holes to Weyl systems and back

   Author : Jorge Laraña Aragón; Bo Sundborg; Lárus Thorlacius; Emil J. Bergholtz; Ulf Gran; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Linear response; Black holes; Thermalization; Holography; Weyl systems; Non-Hermitian systems; Theoretical Physics; teoretisk fysik;

   Abstract : Linear response theory is a powerful calculation tool in quantum field theory. We apply this framework to a variety of models originating from distinct areas in theoretical physics and for different reasons. READ MORE
