From: On the possibility of many-body localization in a doped Mott insulator
Main panel: the Nagaoka polaron energy ε1h with total spin S = 5/2 at 
.
The fitting of Eq. (2) shows that teff = 5.82 × 10−5tx and L0 = 11.97, indicating a substantial mass enhancement m*/m = (teff/tx)−1 = 1.7180 × 104. Inset: the comparison of ε1h at β = 1/3 and 1/4, respectively. The hole forms a conventional quasiparticle (with S = 1/2) at 
, with teff/tx = 0.489 or m*/m ≃ 2.04.
