The phase diagram of the two-leg t-Jz ladder is explored, using the density-matrix renormalization group method. Results are obtained for energy gaps, electron density profiles, and correlation functions for the half filled and quarter filled cases. The effective Lagrangian velocity parameter v is shown to vanish at half filling. The behavior of the one-hole gap in the Nagaoka limit is investig...

Since the discovery of superconductivity in infinite-layer nickelates ${\mathrm{RNiO}}_{2}$ (R = La, Pr, Nd), great research efforts have been made to unveil its underlying superconducting mechanism. However, physical origin intriguing hole-doped phase diagram, characterized by a dome sandwiched between two weak insulators, is still unclear. Here we present microscopic theory for electronic str...

An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

Weanalyze the quantumphases, correlation functions and edgemodes for a class of spin-1/2 and fermionicmodels related to the one-dimensional Ising chain in the presence of a transverse field. Thesemodels are the Ising chainwith anti-ferromagnetic long-range interactions that decaywith distancer as a r 1 , as well as a related class of fermionicHamiltonians that generalize theKitaev chain, where...

We revisit the nature of the far infrared (FIR)/Radio correlation by means of the most recent models for star forming galaxies, focusing in particular on the case of obscured starbursts. We model the IR emission with our population synthesis code, GRASIL (Silva et al. 1998). As for the radio emission, we revisit the simple model of Condon & Yin (1990). We find that a tight FIR/Radio correlation...

Gamma ray bursts (GRBs) have recently attracted much attention as a possible way to extend the Hubble diagram to very high redshift. To this aim, the luminosity (or isotropic emitted energy) of a GRB at redshift z must be evaluated from a correlation with a distance independent quantity so that one can then solve for the luminosity distance DL(z) and hence the distance modulus μ(z). Averaging o...

water quality in each area, indicates the impact of geology, climate and anthropogenic pollutants. monitoring of water quality in most cases result in complex data which shows the perfect act of water resources, so they need appropriate method for analyzing. in this study hydro-chemical evaluation of hiv basin which located in west of hashtgerd have been done. to measure the concentration of ma...
