| Research Abstract |
Exotic phenomena such as the transition to quark matter and the meson condensation may occur in high density matter realized inside the neutron stars. In the present study, researchers in hadronic physics and atomic physics work together and investigate (1) the classification of the QCD phases, (2) strongly coupled quark matter and the neutron star structure, (3) lattice QCD simulations of the multi-baryon systems, and (4) quantum phenomena in cold atomic gasses. We have found that novel effect of the hadron-quark crossover to the mass of neutron stars, and also a possibility of simulating the meson condensation in dense hadronic matter by using cold atoms/molecules in the laboratory.
