Fermion kinetics in the Falicov-Kimball limit of the three-band Emery model
D. K. Sunko
The three-band Emery model is reduced to a single-particle quantum model of Falicov-Kimball type, by allowing only up-spins to hop, and forbidding double occupation by projection.…
The Gutzwiller wave function as a disentanglement prescription
D. K. Sunko
The Gutzwiller variational wave function is shown to correspond to a particular disentanglement of the thermal evolution operator, and to be physically consistent only in the tempe…
Entropy saturation and the Brinkmann-Rice transition in a random-tiling model
D. K. Sunko
The parameter regime in which a Brinkmann-Rice (BR) transition appears near half-filling is investigated for a model of of one kind of electrons traversing a plane randomly tiled w…
Quantum phase transition in a random-tiling model
D. K. Sunko
The analogue of a Mott-Hubbard transition is discussed, which appears at an incommensurate filling in a model of a two-dimensional plane, randomly tiled with CuO_4 `molecules', sim…
