Pressure - temperature phase diagram of generalized Hubbard model with correlated hopping at half - filling
In the present paper pressure-temperature phase diagram of a generalized Hub-bard model with correlated hopping in a paramagnetic state at half-filling is determined by means of the generalized mean-field approximation in the Green function technique. The constructed phase diagram describes metal-to-insulator transition with increasing temperature, and insulator-to-metal transition under the ac...
متن کاملPhase diagram of the Holstein-Hubbard two-leg ladder using a functional renormalization-group method
Using a functional renormalization-group method, we obtain the phase diagram of the two-leg ladder system within the Holstein-Hubbard model, which includes both electron-electron and electron-phonon interactions. Our renormalization-group technique allows us to analyze the problem for both weak and strong electronphonon couplings. We show that, in contrast to results from conventional weak-coup...
متن کاملPhase diagram of the two-leg Kondo ladder
The phase diagram of the two-leg Kondo ladder is investigated using computational techniques. Ferromagnetism is present, but only at small conduction electron densities and robust Kondo coupling J. For densities n*0.4 and any Kondo coupling, a paramagnetic phase is found. We also observed spin dimerization at densities n=1/4 and n=1/2. The spin-structure factor at small J peaks at qW = s2n ,0dp...
متن کاملPhase diagram of the three-dimensional Hubbard model at half filling
We investigate the phase diagram of the three-dimensional Hubbard model at half filling using quantumMonte Carlo (QMC) simulations. The antiferromagnetic Néel temperature TN is determined from the specific heat maximum in combination with finite-size scaling of the magnetic structure factor. Our results interpolate smoothly between the asymptotic solutions for weak and strong coupling, respecti...
متن کامل0 Numerical Studies of the two - leg Hubbard ladder
The Hubbard model on a two-leg ladder structure has been studied by a combination of series expansions at T = 0 and the density-matrix renormal-ization group. We report results for the ground state energy E 0 and spin-gap ∆ s at half-filling, as well as dispersion curves for one and two-hole excita-tions. For small U both E 0 and ∆ s show a dramatic drop near t/t ⊥ ∼ 0.5, which becomes more gra...
