Ferromagnetism in quark matter and origin of the magnetic field in compact stars
T. Tatsumi, T. Maruyama, E. Nakano +1
Two magnetic aspects of quark matter, ferromagnetism and spin density wave, are discussed in the temperature-density plane. Some implications of ferromagnetism are suggested on rel…
Photoproduction of -mesons off C and Cu nuclei for photon energies below 1.1 GeV
T. Kinoshita, H. Yamazaki, H. Fukasawa +40
The -meson photoproduction cross sections have been measured on the C and Cu targets for the photon energies between 600 and 1100 MeV to investigate the behavior of the …
Nuclear Electromagnetic Current in the Relativistic Approach with the Momentum-Dependent Selfenergies
Tomoyuki Maruyama, Satoshi Chiba
We define the new description of the electromagnetic current to hold the current conservation in the momentum-dependent Dirac fields from the Ward Takahashi identity. To describe t…
Monopole Oscillations and Dampings in Boson and Fermion Mixture in the Time-Dependent Gross-Pitaevskii and Vlasov Equations
Tomoyuki Maruyama, Hiroyuki Yabu, Toru Suzuki
We construct a dynamical model for the time evolution of the boson-fermion coexistence system. The dynamics of bosons and fermions are formulated with the time-dependent Gross-Pita…
Spin excitations in fermion condensates
Tomoyuki Maruyama, George F. Bertsch
We investigate collective spin excitations in two-component fermion condensates with special consideration of unequal populations of the two components. The frequencies of monopole…
Kaon Condensation and Lambda-Nucleon Loop in the Relativistic Mean-Field Approach
Tomoyuki Maruyama, Takumi Muto, Toshitaka Tatsumi +2
The possibility of kaon condensation in high-density symmetric nuclear matter is investigated including both s- and p-wave kaon-baryon interactions within the relativistic mean-fie…
