Medium-induced bosonic clusters in a Bose-Fermi mixture: Towards simulating cluster formations in neutron-rich matter
Yixin Guo, Hiroyuki Tajima
Considering bosonic atoms immersed in a dilute Fermi gas, we theoretically investigate medium-induced bosonic clusters associated with fermion-mediated two- and three-body interact…
Cooper pairing and tripling in one-dimensional spinless fermions with attractive two- and three-body forces
Yixin Guo, Hiroyuki Tajima
We theoretically investigate in-medium three-body correlations in one-dimensional spinless fermions with antisymmetrized two- and three-body attractive interactions. By investigati…
Finite-range effect in the two-dimensional density-induced BCS-BEC crossover
Hikaru Sakakibara, Hiroyuki Tajima, Haozhao Liang
We theoretically investigate the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensation (BEC) crossover in a two-dimensional Fermi gas with the finite-range interaction by u…
Spin transport between polarized Fermi gases near the ferromagnetic phase transition
Tingyu Zhang, Daigo Oue, Hiroyuki Tajima +2
We theoretically study the spin current between two polarized Fermi gases with repulsive interactions near the itinerant ferromagnetic phase transition. We consider a two-terminal…
Exploring Superfluid in Dilute Spin-Polarized Neutron Matter
Hiroyuki Tajima, Hiroshi Funaki, Yuta Sekino +2
We explore the theoretical possibility of neutron superfluid in dilute spin-polarized neutron matter, which may be relevant to the crust region of a magnetized neutron star…
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…
BCS-BCS crossover between atomic and molecular superfluids in a Bose-Fermi mixture
Yixin Guo, Hiroyuki Tajima, Tetsuo Hatsuda +1
We theoretically examine a continuity between atomic and molecular Fermi superfluids in a Bose-Fermi mixture near the Feshbach resonance. Considering a two-channel model describing…
Brueckner -matrix approach to two-dimensional Fermi gases with the finite-range attractive interaction
Hikaru Sakakibara, Hiroyuki Tajima, Haozhao Liang
Two-dimensional spin-1/2 fermions with the finite-range interaction are theoretically studied. Characterizing the attractive interaction in terms of the scattering length and the e…
