We compute the critical behaviour of three-dimensional scalar theories using a new exact non-perturbative evolution equation. Our values for the critical exponents agree well with previous precision estimates.

  1. Coarse graining from within: Wilson-Fisher universality on $S^3$

    hep-th 2026-06 unverdicted novelty 7.0 of 10

    A spectral cutoff RG flow on S^3 realizes the Wilson-Fisher universality class with one relevant direction and critical exponents close to flat-space values.

  2. FRG analysis for a relativistic BEC in arbitrary spatial dimensions

    hep-ph 2025-04 conditional novelty 6.0 of 10

    Functional renormalization group flows of a relativistic complex scalar at finite chemical potential confirm that the condensate vanishes for d≤2 in agreement with Mermin-Wagner, while surviving for d>2.
