  Anderson localization (AL) phenomena usually exists in systems with random
potential. However, disorder-free quantum many-body systems with local
conservation can also exhibit AL or even many-body localization transition. In
this work, we show that the AL phase exists in a modified Kondo lattice without
external random potential. The density of state, inverse participation ratio
and temperature-dependent resistance are computed by classical Monte Carlo
simulation, which uncovers the AL phase from previously studied Fermi liquid
and Mott insulator regime. The occurrence of AL roots from quenched disorder
formed by conservative localized moments. Interestingly, a many-body
wavefunction is found, which captures elements in all three paramagnetic phases
and is used to compute their quantum entanglement. In light of these findings,
we expect the disorder-free AL phenomena can exit in generic
translation-invariant quantum many-body systems.
