چکیده

We present results of an exact diagonalization calculation of the spectral function A(k, ω) for a single hole described by the t–J model propagating on a 32–site square cluster. The minimum energy state is found at a crystal momentum k = (π2 , π 2 ), consistent with theory, and our measured dispersion relation agrees well with that determined using the self–consistent Born approximation. In contrast to smaller cluster studies, our spectra show no evidence of string resonances. We also make a qualitative comparison of the variation of the spectral weight in various regions of the first Brillouin zone with recent ARPES data.

Typeset Using Revt E X 1

Low energy and dynamical properties of a single hole in the t − J z model Abstract We review in details a recently proposed technique to extract information about dynamical correlation functions of many-body hamiltonians with a few Lanczos iterations and without the limitation of finite size. We apply this technique to understand the low energy properties and the dynamical spectral weight of a ...

Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice

In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4),  ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...

Single-hole properties of the t-J model on the honeycomb lattice

Motivated by the possible charge ordering in the recently discovered superconductor NaxCoO2 yH2O, which at filling x=1/3 would correspond to a half-filled honeycomb lattice, we investigate the single-hole dynamics of the t-J model on this lattice. Using exact diagonalization, series expansion, and the self-consistent Born approximation, we calculate the quasiparticle dispersion, bandwidth, and ...

Four different types of a single drop dripping down a hole under gravity by lattice Boltzmann method

In this paper the dynamic of a droplet on a surface with a hole is investigated under gravitational effect by using lattice Boltzmann method. Incompressible two-phase flow with high density ratio proposed by Lee is considered. Cahn’s theory is used to observe the wettability of the surface in contact with liquid and gas phases. Several parameters such as contact angle, surface tension and gravi...

Optical absorption and single – particle excitations in the 2 D Holstein t – J model

Optical absorption and single–particle excitations in the 2D Holstein t–J model Abstract To discuss the interplay of electronic and lattice degrees of freedom in systems with strong Coulomb correlations we have performed an extensive numerical study of the two–dimensional Holstein t–J model. The model describes the interaction of holes, doped in a quantum antiferromagnet, with a dispersionsless...
