Pionic BEC--BCS crossover at finite isospin chemical potential
Masayuki Matsuzaki
We study the character change of the pionic condensation at finite isospin chemical potential μ_\mathrm{I} by adopting the linear sigma model as a non-local interaction between qua…
Determination of QCD phase diagram from the imaginary chemical potential region
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
We test the reliability of the the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model, comparing the model result with the lattice data at nonzero imaginary chemical potential.…
Meson mass at real and imaginary chemical potentials
Kouji Kashiwa, Masayuki Matsuzaki, Hiroaki Kouno +2
The chemical-potential dependence of pi and sigma meson masses is analyzed at both real and imaginary chemical potentials, and , by using the Polyakov-…
Vector-type four-quark interaction and its impact on QCD phase structure
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
Effects of the vector-type four-quark interaction on QCD phase structure are investigated in the imaginary chemical potential region, by using the Polyakov-loop extended Nambu-Jona…
Correlations among discontinuities in QCD phase diagram
Kouji Kashiwa, Yuji Sakai, Hiroaki Kouno +2
We show, in general, that when a discontinuity of either zeroth-order or first-order takes place in an order parameter such as the chiral condensate, discontinuities of the same or…
Critical endpoint in the Polyakov-loop extended NJL model
Kouji Kashiwa, Hiroaki Kouno, Masayuki Matsuzaki +1
The critical endpoint (CEP) and the phase structure are studied in the Polyakov-loop extended Nambu--Jona-Lasinio model in which the scalar type eight-quark (σ^4) interaction and t…
Effects of a multi-quark interaction on color superconducting phase transition in an extended NJL model
Kouji Kashiwa, Masayuki Matsuzaki, Hiroaki Kouno +1
We study the interplay of the chiral and the color superconducting phase transitions in an extended Nambu--Jona-Lasinio model with a multi-quark interaction that produces the nonli…
Spatial structure of quark Cooper pairs in a color superconductor
Masayuki Matsuzaki
Spatial structure of Cooper pairs with quantum numbers color 3^*, I=J=L=S=0 in ud 2 flavor quark matter is studied by solving the gap equation and calculating the coherence length…
