Query: Semiclassical Quark Model Of the Nuclear Matter Response   The longitudinal response function $R(q,w)$\ of nuclear matter is calculated
in a semiclassical quark model. The model has a many- body string-flip
potential that confines quarks into hadrons and avoids color van der Waals
forces. Molecular dynamics simulations are used to calculate $R(q,w)$\ in one
space dimension for a variety of momentum transfers $q$\ and excitation
energies $w$. The response function decreases with density (compared to a free
hadron response) because of quark exchange between hadrons.
