| Research Abstract |
Self-dual cones in the Hilbert space naturally induce useful operator inequalities. We studied mathematical aspects of the inequalities and applied these to the condensed matter physics. For instance, the Holstein-Hubbard, SSH and Frohlich models are investigated from the viewpoint of our operator inequalities. We showed that ground states are unique in the Holstein-Hubbard and SSH models. This reveals interesting magnetic structures in the ground states.
