  In the spinless fermion model on a square lattice with infinite
nearest-neighbor repulsion, holes doped into the half-filled ordered state form
stripes which, at low doping, are stable against phase separation into an
ordered state and a hole-rich metal. Here we consider transport of additional
holes along these stripes. The motion of a single hole on a stripe is mapped to
a one-dimensional problem, a variational wavefunction is constructed and the
energy spectrum is calculated and compared to energies obtained by exact
diagonalization.
