Abstract

In this folder there are the experimental and theoretical data displayed in the Figures of the manuscript. In particular: # 'Fig2c_Fermi-Bose.xlsx' and 'ExtendedDataFig1c_Fermi-Fermi.xlsx' are the data presented in Fig.2c and Extended Data Fig.1 (all the data of the polaron energy as a function of the impurity concentration for the Fermi-Bose and Fermi-Fermi mixture, respectively). Note that these contain also the data presented in the b) panels. These data are excel files in which each sheet, named after the value of the interaction parameter X, contains: Sequence: date and name of the experimental sequence CK_non_int: concentration of the non interacting impurities EF: Fermi energy of the Fermi sea (in kHz) EF err: error on the Fermi energy of the Fermi sea (in kHz) T/TF: reduced temperature of the Fermi sea T/TFK: reduced temperature of the impurities (present only in 'ExtendedDataFig1c_Fermi-Fermi.xlsx') X: dimensionless interaction parameter kFR*: dimensionless resonance range parameter CK_int: concentration of the interacting impurities (note that the additional factor 1/2, used in the analysis in order to take into account the RF transfer, is not present in these data) Delta/vF: polaron energy (in Fermi energy) Delta/vF err: error on the polaron energy (in Fermi energy) # 'Fig2a.txt' and 'ExtendedDataFig1a.txt' are the RF spectra presented in Fig.2a and Extended Data Fig.1a, respectively. The format is: col1: DE/EF (spectroscopic frequency related to bare frequency in…
