Dirac-mode analysis for quark number density and its application for deconfinement transition
Takahiro M. Doi, Kouji Kashiwa
The quark number density at finite imaginary chemical potential is investigated in the lattice QCD using the Dirac-mode expansion. We find the analytical formula of the quark numbe…
On a modification method of Lefschetz thimbles
Shoichiro Tsutsui, Takahiro M. Doi
The QCD at finite density is not well understood yet, where standard Monte Carlo simulation suffers from the sign problem. In order to overcome the sign problem, the method of Lefs…
Relating Quark Confinement and Chiral Symmetry Breaking in QCD
Hideo Suganuma, Takahiro M. Doi, Krzysztof Redlich +1
We study the relation between quark confinement and chiral symmetry breaking in QCD. Using lattice QCD formalism, we analytically express the various "confinement indicators", such…
Modifying partition functions: a way to solve the sign problem
Takahiro M. Doi, Shoichiro Tsutsui
A possible method to solve the sign problem is developed by modifying the original theory. Considering several modifications of the partition function, the observable in the origin…
Dirac-mode expansion of quark number density and its implications of the confinement-deconfinement transition
Takahiro M. Doi, Kouji Kashiwa
We investigate the quark number density at finite imaginary chemical potential by using the Dirac-mode expansion. In the large quark mass region, it is found that the quark number…
