Density-Induced Hadron-Quark Crossover via the Formation of Cooper Triples
Hiroyuki Tajima, Shoichiro Tsutsui, Takahiro M. Doi +1
We discuss the hadron--quark crossover accompanied by the formation of Cooper triples (three-body counterpart of Cooper pairs) by analogy with the Bose--Einstein condensate to Bard…
Competition between pairing and tripling in one-dimensional fermions with coexistent s- and p-wave interactions
Yixin Guo, Hiroyuki Tajima
We theoretically investigate in-medium two- and three-body correlations in one-dimensional two-component Fermi gases with coexistent even-parity s-wave and odd-parity p-wave intera…
Stability against three-body clustering in one-dimensional spinless p-wave fermions
Yixin Guo, Hiroyuki Tajima
We theoretically investigate in-medium two- and three-body correlations in one-dimensional spinless fermions with attractive two-body p-wave interaction. By investigating the varia…
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 …
Possible condensation of Cooper triples
Sora Akagami, Hiroyuki Tajima, Kei Iida
We theoretically discuss the possible condensation of Cooper triples, which correspond to a three-body version of Cooper pairs, in three-component Fermi systems with three-body att…
Role of the effective range in the density-induced BEC-BCS crossover
Hiroyuki Tajima, Haozhao Liang
We elucidate the role of the effective range in the Bose-Einstein-condensate (BEC) to Bardeen-Cooper-Schrieffer (BCS) crossover regime of two-component fermions in three dimensions…
Isothermal compressibility and effects of multi-body molecular interactions in a strongly interacting ultracold Fermi gas
Daichi Kagamihara, Ryohei Sato, Koki Manabe +2
We theoretically investigate the isothermal compressibility in the normal state of an ultracold Fermi gas. Including pairing fluctuations, as well as preformed-pair formati…
Dominant Andreev Reflection through Nonlinear Radio-Frequency Transport
Tingyu Zhang, Hiroyuki Tajima, Yuta Sekino +2
We theoretically propose the laser-induced Andreev reflection between two-component Fermi superfluid and normal states via spatially-uniform Rabi couplings. By analyzing the tunnel…
Nonequilibrium noise as a probe of pair-tunneling transport in the BCS--BEC Crossover
Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo +1
The detection of elementary carriers in transport phenomena is one of the most important keys to understand non-trivial properties of strongly-correlated quantum matter. Here we pr…
