Deconfinement and CP-breaking at in Yang-Mills theories and a novel phase for SU(2)
Shi Chen, Kenji Fukushima, Hiromichi Nishimura +1
We discuss the deconfinement and the CP-breaking phase transitions at in Yang-Mills theories. The 't Hooft anomaly matching prohibits the confined phase with CP symmetry and…
Conundrum for the free energy of a holonomous gluonic plasma at cubic order
Christiaan P. Korthals Altes, Hiromichi Nishimura, Robert D. Pisarski +1
We compute the term in the free energy for a gauge theory with nonzero holonomy at nonzero temperature. If the holonomy is generated kinematically by the introdu…
High-temperature domain walls of QCD with imaginary chemical potentials
Hiromichi Nishimura, Yuya Tanizaki
We study QCD with massless quarks on under symmetry-twisted boundary conditions with small compactification radius, i.e. at high temperatures. Under suitab…
Thermal effective potential for the Polyakov loop to higher loop order
Hiromichi Nishimura, Chris Korthals-Altes, Robert D. Pisarski +1
This is a progress report on the calculation of the effective potential for the Polyakov loop in pure gauge theory beyond two-loop order. We introduce a new approach using…
Possible higher order phase transition in large- gauge theory at finite temperature
Hiromichi Nishimura, Robert D. Pisarski, Vladimir V. Skokov
We analyze the phase structure of gauge theory at finite temperature using matrix models. Our basic assumption is that the effective potential is dominated by double-t…
Evading the sign problem in the mean-field approximation through Lefschetz-thimble path integral
Yuya Tanizaki, Hiromichi Nishimura, Kouji Kashiwa
The fermion sign problem appearing in the mean-field approximation is considered, and the systematic computational scheme of the free energy is devised by using the Lefschetz-thimb…
