Gutzwiller wave function under magnetic field
Magnetization process of the Gutzwiller wave function is studied accurately by a variational Monte Carlo method. We apply it to the one-dimensional (1D) and 2D Hubbard models (HM), and to the 1D periodic Anderson model (PAM) without orbital degeneracy. For the HM, magnetization varies discontinuously to the full moment, as the magnetic field increases. For the PAM, the paramagnetic state is uns...
متن کاملFunction of vitrified mouse ovaries tissue under static magnetic field after autotransplantation
This study was designed to investigate the effects of applying 1 mT static magnetic field (SMF) during the vitrification process, on the viability of ovarian follicles after vitrification-warming and autotransplantation. The study was conducted in two phases. In the first phase, ovaries of female NMRI mice (6 to 8 weeks old) were randomly divided into three groups: 1- Freshly isolated ovaries f...

متن کاملExact analytic results for the Gutzwiller wave function with finite magnetization
We present analytic results for ground-state properties of Hubbard-type models in terms of the Gutzwiller variational wave function with nonzero values of the magnetization m. In dimension D51 approximation-free evaluations are made possible by appropriate canonical transformations and an analysis of umklapp processes. We calculate the double occupation and the momentum distribution, as well as...
متن کاملGutzwiller wave function in the three-band Hubbard model: A variational Monte Carlo study.
The Gutzwiller wave function for the three-band Hubbard model on a two dimensional CuO2 plane is studied by using the variational Monte Carlo (VMC) method in the limit Ud → ∞, where Ud is the Coulomb repulsion between holes on a Cu site. The VMC results for the energy and the fraction of d-holes are compared with those of the Rice-Ueda type Gutzwiller approximation (GA). The difference between ...
