Polaronic Proton and Diproton Clustering in Neutron-Rich Matter
Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2
We show that strong spin-triplet neutron-proton interaction causes polaronic protons to occur in neutron matter at subnuclear densities and nonzero temperature. As the neutron dens…
Resonance-to-bound transition of He in neutron matter and its analogy with heteronuclear Feshbach molecule
Hiroyuki Tajima, Hajime Moriya, Wataru Horiuchi +2
We theoretically investigate the fate of a neutron-alpha -wave resonance in dilute neutron matter, which may be encountered in neutron stars and supernova explosions. While …
Dissipation-relaxation dynamics of a spin-1/2 particle with a Rashba-type spin-orbit coupling in an ohmic heat bath
Tomohiro Hata, Eiji Nakano, Kei Iida +2
Spin-orbit coupling (SOC), which is inherent to a Dirac particle that moves under the influence of electromagnetic fields, manifests itself in a variety of physical systems includi…
Binding two and three particles in cold neutron matter
H. Moriya, H. Tajima, W. Horiuchi +2
We elucidate the fate of neighboring two and three- particles in cold neutron matter by focusing on an analogy between such systems and Fermi polarons realized in ultracold…
Polaron Problems in Ultracold Atoms: Role of a Fermi Sea across Different Spatial Dimensions and Quantum Fluctuations of a Bose Medium
Hiroyuki Tajima, Junichi Takahashi, Simeon I. Mistakidis +2
The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and inter…
Extracting non-local inter-polaron interactions from collisional dynamics
Junichi Takahashi, Hiroyuki Tajima, Eiji Nakano +1
This study develops a novel experimental method of deducing the profile of interaction induced between impurities in a trapped gas of ultracold Fermi/Bose atoms, which are often re…
