Fig. 1. (Color online) Energy of repulsive polaron vs. the scaled interaction strength $g/2k_{F}$ calculated by the variational method for different mass ratios: solid lines from top to bottom, $m_\downarrow/m_\uparrow=6/40,1,40/6$. The red dot-dashed line is exact BA results for equal masses, the dot transverse line is $E_F$.
