Thermodynamic Potential of the Polyakov Loop in SU(3) Quenched Lattice QCD
Hideo Suganuma, Hiroki Ohata, Masakiyo Kitazawa
Using SU(3) lattice QCD, we study for the first time the effective potential of the Polyakov loop at finite temperature, i.e., the thermodynamic potential, in t…
Phase diagram near the quantum critical point in Schwinger model at : analogy with quantum Ising chain
Hiroki Ohata
The Schwinger model, one-dimensional quantum electrodynamics, has CP symmetry at due to the topological nature of the term. At zero temperature, it is known that as incr…
A new perspective on thermal transition in QCD
Masanori Hanada, Hiroki Ohata, Hidehiko Shimada +1
Motivated by the picture of partial deconfinement developed in recent years for large- gauge theories, we propose a new way of analyzing and understanding thermal phase transiti…
Monte Carlo study of Schwinger model without the sign problem
Hiroki Ohata
Monte Carlo study of the Schwinger model (quantum electrodynamics in one spatial dimension) with a topological term is very difficult due to the sign problem in the conventiona…
Study of Hadron Masses with Faddeev-Popov Eigenmode Projection in the Coulomb Gauge
Hiroki Ohata, Hideo Suganuma
Using SU(3) lattice QCD, we investigate role of spatial gluons for hadron masses in the Coulomb gauge, considering the relation between QCD and the quark model. From the Coulomb-ga…
Remnants of quark model in lattice QCD simulation in the Coulomb gauge
Hiroki Ohata, Hideo Suganuma
Aiming at the relation between QCD and the quark model, we consider projections of gauge configurations generated in quenched lattice QCD simulations in the Coulomb gauge on a 16$^…
Local correlation among the chiral condensate, monopoles, and color magnetic fields in Abelian projected QCD
Hideo Suganuma, Hiroki Ohata
Using the lattice gauge field theory, we study the relation among the local chiral condensate, monopoles, and color magnetic fields in quantum chromodynamics (QCD). First, we inves…
Clear correlation between monopoles and the chiral condensate in SU(3) QCD
Hiroki Ohata, Hideo Suganuma
We study spontaneous chiral-symmetry breaking in SU(3) QCD in terms of the dual superconductor picture for quark confinement in the maximally Abelian (MA) gauge, using lattice QCD…
Gluonic-Excitation Energies and Abelian Dominance in SU(3) QCD
Hiroki Ohata, Hideo Suganuma
We present the first study of the Abelian-projected gluonic-excitation energies for the static quark-antiquark (Q) system in SU(3) lattice QCD at the quenched level, u…
