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…

Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…
