Topological condensed matter physics and TGD
There has been a lot of talk about the physics Nobel prize received by Kosterlitz, Thouless, and Haldane. There is an article summarizing the work of KTH in rather detailed manner. The following is an attempt to gain some idea about what are the topics involved.
The notions of topological order, topological physics, and topological materials pop up in the discussions. I have worked for almost 4 decades with Topological Geometrodynamics and it is somehow amusing how little I know about the work done in condensed matter physics.
The pleasant surprise is that topological order seems to have rather precise counterpart in TGD at the level of fundamental physics: in standard model it would emerge. In any case, it is clear that condensed matter physicists have taken the lead during last 32 years when particle physicists have been wandering in stringy landscape.
