Hawking Radiation 2

In the article Topological order and Quantum TGD, topological order and its category theoretical description are considered from TGD point of view - category theoretical notions are indeed very natural in TGD framework. The basic finding is that the concepts developed in condensed matter physics (topological order, rough description of states as tangles (graphs imbedded in 3-D space), ground state degeneracy, surface states protected by symmetry or topology) fit very nicely to TGD framework and has interpretation in terms of the new space-time concept. This promises applications also in the conventional areas of condensed matter physics such as more precise description of solid, liquid, and gas phases. See the chapter Criticality and dark matter of "Hyper-finite Factors, p-Adic Length Scale Hypothesis, and Dark Matter Hierarchy" For a summary of earlier postings see Links to the latest progress in TGD.
