Article Synopsis
- The study explores the advantages of the new single-boson exchange (SBE) method applied to the one-loop functional renormalization group (fRG) in analyzing the two-dimensional Hubbard model on a square lattice.
- It examines how fermion-boson Yukawa couplings and physical susceptibilities change with temperature and interaction strength, revealing that SBE simplifies calculations significantly compared to traditional fRG methods, especially in weak-coupling scenarios.
- Additionally, the SBE method maintains finite values at the pseudo-critical transition, unlike conventional fRG, leading to reduced numerical complexity, which could benefit future advanced multiboson research.
