11.05.2023 | Jean-Bernard Bru (Universidad del País Vasco) From Short-Range to Mean-Field Models in Lattice Quantum Systems Realistic interparticle interactions of quantum many-body systems are largely seen as short-range. By contrast, mean-field models come from different approximations or Ansätze but are technically advantageous, by allowing explicit computations while capturing surprisingly well many physical phenomena. We will establish a precise mathematical relation between mean-field and short-range models, by using the long-range limit that is known in the literature as the Kac limit. This paves the way for studying phase transitions, or at least important fingerprints of them like strong correlations at long distances, for models having interactions whose ranges are finite, but very large. It also sheds a new light on mean-field models. Contact: Stefan |
