Exact-diagonalization study of the one-dimensional disordered XXZ model.
We investigate the one-dimensional quantum XXZ model in the presence of diagonal disorder. Recently the model has been analyzed with the help of field-theoretical renormalization group methods, and a phase diagram has been predicted. We study the model with exact diagonalization techniques up to chain lengths of 16 sites. Using finite-size scaling methods we estimate critical exponents and the ...
متن کاملPhase competitions and coexistences in quasi-one-dimensional molecular conductors: exact diagonalization study
We investigate ground state properties of a quasi-one-dimensional electron-lattice coupled model for quarter-filled molecular conductors. The effective one-dimensional extended Hubbard model coupled to adiabatic lattice degree of freedom is derived by the inter-chain mean-field approximation and solved by Lanczos exact diagonalization method. We find that the critical behavior among lattice tet...
متن کاملExact diagonalization results for resonant inelastic x-ray scattering spectra of one-dimensional Mott insulators
We examine the momentum-dependent excitation spectra of indirect as well as direct resonant inelastic x-ray scattering (RIXS) processes in half-filled (extended) Hubbard rings. We determine the fundamental features of the ground-state RIXS response and discuss the experimental conditions that can allow for the low-energy part of these features to be distinguished in one-dimensional copper-oxide...
متن کاملExact diagonalization study of the two-dimensional t-J-Holstein model.
Exact diagonalization study of the two-dimensional t − J−Holstein model (Received today) We study by exact diagonalization the two-dimensional t − J−Holstein model near quarter filling by retaining only few phonon modes in momentum space. This truncation allows us to incorporate the full dynamics of the retained phonon modes. The behavior of the kinetic energy, the charge structure factor and o...
