Finite-temperature properties of extended Nagaoka ferromagnetism
Hiroaki Onishi, Seiji Miyashita
We study finite-temperature properties of a Hubbard model including sites of a particle bath which was proposed as a microscopic model to show itinerant ferromagnetism at finite el…

Variational Wavefunction for the Periodic Anderson Model with Onsite Correlation Factors
Katsunori Kubo, Hiroaki Onishi
We propose a variational wavefunction containing parameters to tune the probabilities of all the possible onsite configurations for the periodic Anderson model. We call it the full…

Doping control of realization of an extended Nagaoka ferromagnetic state from the Mott state
Hiroaki Onishi, Seiji Miyashita
Inspired by the Nagaoka ferromagnetism, we propose an itinerant model to study the transition between the Mott singlet state and a ferromagnetic state by emulating a doping process…
