Diffraction spectrum of lattice gas models above T

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/156596The diffraction spectra of lattice gas models on Z^d with finite-range ferromagnetic two-body interaction above T_c or with certain rates of decay of the potential are considered. We show that these diffraction spectra almost surely exist, are Z^d-periodic and consist of a pure point part and an absolutely continuous part with continuous density.9 pages, no figuresMathematical Physics52C07, 42B05, 60D05, 82B20Diffraction spectrum of lattice gas models above T_ctext
