Finite-range effects in ultradilute quantum drops

In the first experimental realization of dilute Bose–Bose liquid drops using two hyperfine states of 39K some discrepancies between theory and experiment were observed. The standard analysis of the data using the Lee–Huang–Yang beyond mean-field theory predicted critical numbers which were significa...
