  Whether a doped hole propagates as a Bloch wave or not is an important issue
of doped Mott physics. Here we examine this problem based on the quasiparticle
spectral weight $Z$ distribution, calculated by density matrix renormalization
group (DMRG). By tuning the anisotropy of a two-leg $t$-$J$ ladder without
closing the background spin gap, the $Z$ distribution unambiguously reveals a
transition of the single hole state from a Bloch wave to a novel one with
spontaneous translational symmetry breaking. We further establish a direct
connection of such a transition with a nonlocal phase string entanglement
between the hole and quantum spins, which explains numerical observations.
