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…
