Lattice QCD study of confinement and chiral symmetry breaking with Dirac-mode expansion
Hideo Suganuma, Shinya Gongyo, Takumi Iritani
Using the eigen-mode of the QCD Dirac operator $\Slash D=γ^μD^μ$, we develop a manifestly gauge-covariant expansion and projection of the QCD operators such as the Wilson loop and…
Polyakov loop analysis with Dirac-mode expansion
Takumi Iritani, Shinya Gongyo, Hideo Suganuma
In order to investigate the direct relation between confinement and chiral symmetry breaking in QCD, we investigate the Polyakov loop in terms of the Dirac eigenmodes in both confi…
SU(3) lattice QCD study of the gluon propagator in maximally Abelian gauge: off-diagonal gluon mass generation and infrared Abelian dominance
Shinya Gongyo, Hideo Suganuma, Takumi Iritani
We investigate gluon propagators and the effective mass of the gluon fields in the MA gauge with U(1) U(1) Landau gauge fixing in SU(3) lattice QCD. The Monte Carlo…
Analytical derivation of gauge fields from link variables in SU(3) lattice QCD and its application in maximally Abelian gauge
Shinya Gongyo, Hideo Suganuma, Takumi Iritani
In SU(3) lattice QCD, we improve a method to extract gauge fields from link variables analytically. With this method, we perform the first study on the effective mass generation of…
Dirac-mode expansion analysis for Polyakov loop
Takumi Iritani, Shinya Gongyo, Hideo Suganuma
To clarify the relation between chiral symmetry breaking and color confinement, we investigate the Polyakov loop in terms of the Dirac eigenmodes in SU(3) lattice QCD. We analyze t…
Dirac-mode expansion for confinement and chiral symmetry breaking
H. Suganuma, S. Gongyo, T. Iritani
We develop a manifestly gauge-covariant expansion and projection using the eigen-mode of the QCD Dirac operator. Applying this method to the Wilson loop and the Polyakov loop, we p…
