They write down a very simple, essentially gravitational Lagrangian on a spacetime which is a direct product of 4d Minkowski and a “very small” non-commutative space F. Then they ask what this Lagrangian looks like in 4d. The answer is, of course, determined by F, and it turns out that there’s a very simple choice of F that gives exactly the Standard Model.
The "Latest from Connes and Chamseddine" refers to the most recent developments and research findings from the collaboration between Alain Connes and Ali Chamseddine, two renowned mathematicians and physicists.
Connes and Chamseddine primarily focus on noncommutative geometry and its applications in theoretical physics, particularly in the field of quantum gravity.
The work of Connes and Chamseddine has had a significant impact on the understanding of fundamental concepts in physics, such as space, time, and matter. Their research has also provided new insights into the unification of the fundamental forces of nature.
Some recent developments from Connes and Chamseddine include their work on the spectral action principle, which aims to unify the Standard Model of particle physics with Einstein's theory of general relativity. They have also made progress in developing a noncommutative version of the Higgs mechanism.
The research of Connes and Chamseddine has the potential to lead to a deeper understanding of the fabric of the universe and the fundamental laws that govern it. Their work may also have practical applications in fields such as quantum computing and space travel.
