Abstract: Quantum many-body problem studies the mathematically rigorous results of interacting many-particle systems consisting of a huge number of particles, each of which obeys the laws of quantum mechanics. The key problems are the classifications of the various phases and the phase transitions. In this talk I will consider the two-dimensional Hubbard model on the honeycomb lattice, which is a prototypical model for describing the conductance of electrons in graphene. With rigorous renormalization group analysis and fermionic cluster expansions we prove that the phase of the ground state is not a fermi liquid. This talk is based on the joint work with Rivasseau.
