Schwinger-Keldysh approach to tunneling transport at a hadron-quark interface

Tingyu Zhang, Hiroyuki Tajima, Motoi Tachibana

We theoretically discuss quantum tunneling transport and frictions at a hadron-quark matter interface based on the Schwinger-Keldysh approach combined with the tunneling Hamiltonia…

Determination of hadron-quark phase transition line from lattice QCD and two-solar-mass neutron star observations

Junpei Sugano, Hiroaki Kouno, Masanobu Yahiro

We aim at drawing the hadron-quark phase transition line in the QCD phase diagram by using the two phase model (TPM) in which the entanglement Polyakov-loop extended Nambu--Jona-La…

Pions are neither perturbative nor nonperturbative: Wilsonian renormalization group analysis of nuclear effective field theory including pions

Koji Harada, Hirofumi Kubo, Yuki Yamamoto

Pionful nuclear effective field theory (NEFT) in the two-nucleon sector is examined from the Wilsonian renormalization group point of view. The pion exchange is cut off at the floa…

The axial anomaly and the phases of dense QCD

Gordon Baym, Tetsuo Hatsuda, Motoi Tachibana +1

The QCD axial anomaly, by coupling the chiral condensate and BCS pairing fields of quarks in dense matter, leads to a new critical point in the QCD phase diagram \cite{HTYB,chiral2…

Chiral phase transition in an extended NJL model with higher-order multi-quark interactions

Kouji Kashiwa, Hiroaki Kouno, Tomohiko Sakaguchi +2

The chiral phase transition is studied in an extended Nambu--Jona-Lasinio model with eight-quark interactions. Equations for scalar and vector quark densities, derived in the mean…

Two-scale scalar mesons in nuclei

K. Saito, H. Kouno, K. Tsushima +1

We generalize the linear sigma model in order to develop a chiral-invariant model of nuclear structure. The model is natural, and contains not only the usual sigma meson which is t…
