phase structure of QCD from functional renormalization group
Yuepeng Guan, Shinya Matsuzaki, Masatoshi Yamada
We study the low-energy properties of QCD-like theories in the presence of a -odd and axial breaking four-fermion operator $\left( \barÏ Ï\right) \left( \barÏ i γ_5 Ï…

The -vacuum from functional renormalisation
Yuepeng Guan, Jan M. Pawlowski, Masatoshi Yamada
We study topological properties of a quantum mechanical system with -symmetry within the functional renormalisation group (fRG) approach. These properties include the vacuum…

QCD chiral phase diagram from weak functional renormalization group
Yuepeng Guan, Masatoshi Yamada
We investigate the QCD chiral phase transition at finite temperature and finite baryon density using the functional Renormalization Group (fRG). While conventional fRG studies ofte…
