I have been discussing with German Sierra who has worked on rainbow states theoretically. It's interesting that a quench changes local correlations into a global correlation pattern with extensive mutual information.

It would be interesting to understand whether the experimental non-equilibrium #QFT dynamics gives rise to also other states that the inhomogeneous models that originally yielded rainbow correlation patterns, for example at finite temperatures the phase diagram of subblock entropy includes a crossover in the scaling type.

For now the experiment yielded only 1 type of a rainbow state.

here is an other nerdy one with a rather limited venn diagram intersection.

One of the cool things about the online world is access to some really good textbooks. Dr Warren (perfect name #rabbit ) Siegel put out a free and open source textbook on Quantum Field Theory #QFT

Abstract: Following up on the discussion in the previous two chapters, various interesting aspects of QFT in general emerge which we explain and explicitly demonstrate using the current example. These are renormalised couplings and renormalised 1PI vertices, running of them with the scale and renormalisation prescription. The latter basically allows one to relate the mathematical objects we calculate and the observable quantities we measure. Finally, we consider various scenarios of asymptotic behaviour of the coupling as a function of the scale and touch upon the ideas of quantum triviality, UV and IR fixed points and asymptotic freedom. We end our discussion by deriving the “Renormalisation Group Equation” for 1PI vertices and an expression for their anomalous mass dimension.

Learn about handling UV divergences and discuss theories' renormalisability with
Partha Mukhopadhyay from The Institute of Mathematical Sciences, Chennai, at https://enabla.com/pub/1104/about 🎥

Abstract: we introduce the general theme of counter-term renormalisation programme which is an approach to make sense of the UV divergences observed in the previous chapter https://enabla.com/set/173/pub/682/about. In this approach one regularises the divergences, a process that introduces a scale in the problem, and then adds counter terms to the original Lagrangian to absorb the divergences in the physical limit. Based on the patterns of divergences depending on the mass dimension of the coupling, three categories of theories emerge: super-renormalisable, renormalisable and non-renormalisable theories. In our explicit demonstration, we consider dimensional regularisation and calculate certain example integrals whose results will be crucial in the analysis of the next chapter.

Abstract: In this class, we finish the discussion about global anomalies, discussing global anomalies in topological superconductors. Interestingly, the studies of global anomalies in these materials show a different topological invariant from the Altland-Zirnbauer classification. To understand why, we consider the effect of interactions in topological superconductors, showing that the presence of interactions that respect the symmetry can change the topological class, but this is encoded correctly in the anomalies. Further, we discuss the change of the partition functions when using different frames to describe a Chern-Simons term, what gives rise to the framing anomaly.

🤔Curious? Chat with Partha Mukhopadhyay from The Institute of Mathematical Sciences, Chennai, at https://enabla.com/pub/682/about 🎥

Abstract: Having developed the diagrammatics in detail, we now address the problem of explicitly computing the diagrams. The study is facilitated by introducing Feynman and Schwinger parametrization of the loop integrands. We argue that generically loop diagrams are fraught with UV divergences coming from large values of the loop momenta. Typically the diverging contribution comes from a “region of coincidence” where all the vertices associated to the loop coincide in position space. Next we introduce a key concept called superficial degree of divergence. We explain what is superficial about it and then state and outline the proof of Weinberg’s theorem associated with it. This allows us to explore the pattern in which divergences appear for power law potentials depending on the mass dimension of the coupling.
