Loop Quantum Gravity for newbies

[QUOTE So Asymptotic Safety can be seen both as a "particle physics" approach, as well as a "condensed matter" one [/QUOTE]

Can anyone give some more details !.

Quick pointer, many details are in the references of post #17. Asymptotic Safety is not emergent. However, the ideas of fundamental/emergent, and non-Gaussian fixed points come from Wilsonian renormalization whose first triumph was to solve the problem of universality at a critical point in condensed matter. Universality is the cool experimental observation that close to a second order phase transition, some "critical exponents" are the same for many different materials with completely different microscopic structures, as long as they share the same dimensionality.
