2. Cetina, M. et al. Ultrafast many-body interferometry of impurities coupled to a Fermi sea. Science 354, 96–99 (2016). This paper presents evidence for the dependence of the Ramsey response of polarons on the impurity concentration.
3. Scazza, F. et al. Repulsive Fermi polarons in a resonant mixture of ultracold 6Li atoms. Phys. Rev. Lett. 118, 083602 (2017). This paper found that the dependence of the energy of polarons on the impurity concentration in a homonuclear mixture was dominated by the mean energy of the impurities.
4. Fritsche, I. et al. Stability and breakdown of Fermi polarons in a strongly interacting Fermi-Bose mixture. Phys. Rev. A 103, 053314 (2021). This paper reports the observation of Fermi polarons created by bosonic impurities and presents preliminary results on polaron–polaron mediated interactions.
5. Yu, Z. & Pethick, C. J. Induced interactions in dilute atomic gases and liquid helium mixtures. Phys. Rev. A 85, 063616 (2012). In this paper the authors derive the mediated interactions between impurities in either a fermionic or bosonic quantum bath.
