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,…
