      abstract     = {The position and strength of the boson peak in silica glass
                      vary considerably with temperature T. Such variations cannot
                      be explained solely with changes in the Debye energy. New
                      Brillouin-scattering measurements are presented which allow
                      determining the T dependence of unrelaxed acoustic
                      velocities. Using a velocity based on the bulk modulus,
                      scaling exponents are found which agree with the
                      soft-potential model. The unrelaxed bulk modulus thus
                      appears to be a good measure for the structural evolution of
                      silica with T and to set the energy scale for the soft
                      potentials.},
