Expansion dynamics in the one-dimensional Fermi-Hubbard model

, 2011
Expansion dynamics of interacting fermions in a lattice are simulated within the one-dimensional (1D) Hubbard model, using the essentially exact time-evolving block decimation (TEBD) method. In particular, the expansion of an initial band-insulator state

Edge singularities in the one-dimensional Bariev model

Nuclear Physics B, 2019
Bariev's model for correlated hopping in one dimension is integrable and soluble within the framework of two nested Bethe Ansätze. For repulsive interaction and finite magnetization the low energy excitation spectrum is a two-component Luttinger liquid ...

Hole Localization in One-Dimensional Doped Anderson-Hubbard Model

, 2008
We study the interplay of disorder and correlation in the one-dimensional hole-doped Hubbard-model with disorder (Anderson-Hubbard model) by using the density-matrix renormalization group method.

One-Particle Excitation of the Two-Dimensional Hubbard Model

, 1997
The real part of the self-energy of interacting two-dimensional electrons has been calculated in the t-matrix approximation. It is shown that the forward scattering results in an anomalous term leading to the vanishing renormalization factor of the one ...

Localized Entanglement in one-dimensional Anderson model [PDF]

, 2005
The entanglement in one-dimensional Anderson model is studied. We show that the pairwise entanglement measured by the average concurrence has a direct relation to the localization length.

Quantum Correlation in One-dimensional Extend Quantum Compass Model

, 2012
We study the correlations in the one-dimensional extended quantum compass model in a transverse magnetic field. By exactly solving the Hamiltonian, we find that the quantum correlation of the ground state of one-dimensional quantum compass model is ...
