Quantum correlations in the spin-1/2 Heisenberg XXZ chain with modulated Dzyaloshinskii-Moriya interaction
F. Khastehdel Fumani, B. Beradze, S. Nemati +2
We study a one-dimensional spin-1/2 XXZ Heisenberg model with alternating Dzyaloshinskii- Moriya interaction, using the numerical Lanczos method. Recently, the ground state (GS) ph…
One-particle spectral function singularities in a one-dimensional gas of spin-1/2 fermions with repulsive delta-function interaction
T. Cadez, S. Nemati, J. M. P. Carmelo
The momentum, fermionic density, spin density, and interaction dependencies of the exponents that control the (momentum-energy)-plane singular features of the one-fermion spectral…
Absence of ballistic charge transport in the half-filled 1D Hubbard model
J. M. P. Carmelo, S. Nemati, T. Prosen
Whether in the thermodynamic limit of lattice length infinite, hole concentration tending to zero, nonzero temperature, and U/t > 0 the charge stiffness of the 1D Hubbard model wit…
From fidelity to entanglement of entropy of the one-dimensional transverse-field quantum compass model
Mostafa Motamedifar, Somayyeh Nemati, Saeed Mahdavifar +1
We study fidelity and fidelity susceptibility by addition of entanglement of entropy in the one-dimensional quantum compass model in a transverse magnetic field numerically. The wh…
Concurrence and entanglement entropy in a dimerized spin-1/2 two-leg ladder
Somayyeh Nemati, Saeed Mahdavifar, Saeed Batebi
We consider the isotropic spin-1/2 two-leg ladders with the dominant spatially modulated rung exchanges. We study the effect of a uniform magnetic field on the ground state phase d…
