Emergent Weyl Nodes and Berry Curvature in Bose Polarons via -Wave Feshbach Coupling
Hiroyuki Tajima, Eiji Nakano, Kei Iida
We show that an impurity quasiparticle immersed in a Bose-Einstein condensate, known as a Bose polaron, exhibits topological properties characterized by a nonzero Berry curvature,…
Tunable Fujita-Miyazawa-Type Three-Body Force in Ultracold Atoms
Hiroyuki Tajima, Eiji Nakano, Kei Iida
We show how a Fujita-Miyazawa-type three-body force emerges among three impurity atoms immersed in an atomic Bose-Einstein condensate near an interspecies Feshbach resonance. As a…
Polaronic neutron in dilute alpha matter: A -wave Bose polaron
Hiroyuki Tajima, Hajime Moriya, Tomoya Naito +3
We theoretically investigate quasiparticle properties of a neutron immersed in an alpha condensate, which is one of the possible states of dilute symmetric nuclear matter. The reso…
Intersections of ultracold atomic polarons and nuclear clusters: How is a chart of nuclides modified in dilute neutron matter?
Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2
Neutron star observations, as well as experiments on neutron-rich nuclei, used to motivate one to look at degenerate nuclear matter from its extreme, namely, pure neutron matter. A…
Structure of two- and three-alpha systems in cold neutron matter
H. Moriya, H. Tajima, W. Horiuchi +2
We present stability and structure of two- and three-alpha systems embedded in dilute cold neutron matter. By solving a few-alpha Schrödinger equation with quasiparticle properties…
Magnetism and superconductivity in quark matter
T. Tatsumi, E. Nakano, K. Nawa
Magnetic properties of quark matter and its relation to the microscopic origin of the magnetic field observed in compact stars are studied. Spontaneous spin polarization appears in…
