  This paper deals with the homogenization problem of one-dimensional
pseudo-elliptic equations with a rapidly varying random potential. The main
purpose is to characterize the homogenization error (random fluctuations),
i.e., the difference between the random solution and the homogenized solution,
which strongly depends on the autocovariance property of the underlying random
potential. It is well known that when the random potential has short-range
dependence, the rescaled homogenization error converges in distribution to a
stochastic integral with respect to standard Brownian motion. Here, we are
interested in potentials with long-range dependence and we prove convergence to
stochastic integrals with respect to Hermite process.
