Fig. 1: Polaron energy including mediated interactions.
From: Mediated interactions between Fermi polarons and the role of impurity quantum statistics
The energy of attractive and repulsive polarons is presented as a function of the dimensionless interaction parameter X according to equation (3) using the static limit for the polaron–polaron-mediated interaction defined in equation (2). The results are shown for the limit of a single impurity (that is, \({{{\mathcal{C}}}}=0\); black dashed lines) and for impurity concentration \({{{\mathcal{C}}}}=0.5\) in FB (solid green lines) and FF (solid red lines) K–Li mixtures.
