Experimental realization of fractional Fermi seas in excited 1D Bose gas via interaction-strength ramps, with Friedel oscillations as signatures.
S5 we demonstrate the robustness of the FO by comparing the oscillation as presented in the main text with that of an alternative data set, in the l=2 excited ideal-gas state
