讲座摘要/Abstract: In this talk I will present some recent progress on the construction of ground states of the 2D hubbard model, which is a prototypical model for the study of Fermi liquid-Superconducting phase transitions in quantum many-body theory. Using fermionic cluster expansions, multi-scale analysis and renormalization theory, we proved that the ground state of this model is not a fermi liquid in the mathematical precise sense of Salmhofer. We also derived the non-perturbative critical temperature for the phase transition. This presentation is based on the joint work with V. Rivasseau: arXiv:2108.10852, arXiv:2108.10415 .
