      abstract     = {Correlation functions are the basis for the understanding
                      of many thermodynamic systems that can be directly observed
                      by scattering experiments. In this manuscript, the
                      correlation functions include the steric repulsion of atoms
                      that also leads to distinct shells of neighbors. A free
                      energy is derived on the basis of these assumptions, and in
                      the following the temperature dependence of the density (or
                      specific volume), the typical time scale of the
                      α-relaxation, and the heat capacity. From this, I argue
                      that the glass transition is dominated by the vicinity of a
                      first-order phase transition. While the correlation length
                      stays rather constant in the vicinity of the glass
                      transition, the intensity of the fluctuations is
                      considerably increasing. The scattering amplitude is
                      connected to the cluster size, also introduced in the
                      cooperativity argument. Additionally, correlations of loops
                      are discussed. The additional correlations describe rather
                      small structures. Applying this to scattering intensities, a
                      correlation peak was described that may be connected to the
                      “Boson Peak” or a “cooperativity length.” The new
                      concept of correlation functions on sterically repulsive
                      atoms may find more attention in the wider field of
                      physics.},
