Description
The notion of polarons has been developed to describe in-medium impurity states and interaction effects in the context of condensed-matter physics. Recently it has also been realized in ultracold atoms, which can be regarded as an ideal platform for investigating many-body physics in nuclear matter. In this contribution, we discuss how the polaron properties established in condensed-matter systems can be applied to neutron star matter involving a lot of degrees of freedom such as spin, isospin, and multi-nucleon clusters. We also show the equivalence between a polaron energy of proton in neutron matter and the nuclear symmetry energy.
