Confinement/deconfinement phase transition in SU(3) Yang-Mills theory\n and non-Abelian dual Meissner effect

The dual superconductivity is a promising mechanism of quark confinement. In\nthe preceding works, we have given a non-Abelian dual superconductivity picture\nfor quark confinement, and demonstrated the numerical evidences on the lattice.\n In this talk, we focus on the the confinement and deconfinement phase\ntransition at finite temperature in view of the dual superconductivity. By\nusing our new formulation of lattice Yang-Mills theory and numerical\nsimulations on the lattice, we extract the dominant mode for confinement by\ndecomposing the Yang-Mills field, and we investigate the Polyakov loop average,\nstatic quark potential, chromoelectric flux, and induced monopole current for\nboth Yang-Mills field and decomposed restricted field in both confinement and\ndeconfinement phase at finite temperature. We further discuss the role of the\nchromomagnetic monopole in the confinement/deconfinement phase transition.\n
