The configuration space of causal sets is vast. It is a critical goal to map out this space. Here, we take a practical step towards this goal. We investigate nine classes of causal…

Discovering and quantifying nontrivial fixed points in multi-field models
Astrid Eichhorn, Thomas Helfer, David Mesterházy +1
We use the functional renormalization group and the -expansion concertedly to explore multicritical universality classes for coupled vector-field models in…
