Monopoles of the Dirac type and color confinement in QCD -- First results of SU(3) numerical simulations without gauge fixing
Katsuya Ishiguro, Atsuki Hiraguchi, Tsuneo Suzuki
If non-Abelian gauge fields in QCD have a line-singularity leading to non-commutativity with respect to successive partial-derivative operations, the non-Abelian Bianchi id…
Monopoles of the Dirac type and color confinement in QCD
Tsuneo Suzuki, Atsuki Hiraguchi, Katsuya Ishiguro
We present results of Monte-Carlo studies of a new color confinement scheme proposed recently due to Abelian-like monopoles of the Dirac type corresponding in the continuum…
New Abelian-like monopoles and the dual Meissner effect
Atsuki Hiraguchi, Katsuya Ishiguro, Tsuneo Suzuki
Violation of non-Abelian Bianchi identity can be regarded as Abelian-like monopole currents in the continuum SU(N) QCD. Three Abelian-like monopoles, when defined in SU(2)…
Sparse modeling approach to obtaining the shear viscosity from smeared correlation functions
Etsuko Itou, Yuki Nagai
We propose the sparse modeling method to estimate the spectral function from the smeared correlation functions. We give a description of how to obtain the shear viscosity from the…
Two-colour QCD phases and the topology at low temperature and high density
Kei Iida, Etsuko Itou, Tong-Gyu Lee
We delineate equilibrium phase structure and topological charge distribution of dense two-colour QCD at low temperature by using a lattice simulation with two-flavour Wilson fermio…
Thermodynamics for SU(2) pure gauge theory using gradient flow
Takehiro Hirakida, Etsuko Itou, Hiroaki Kouno
We present the scale-setting function and the equation of state of the pure SU(2) gauge theory using the gradient flow method. We propose a reference scale t0 for the SU(2) gauge t…
