Electron-mediated entanglement of two distant macroscopic ferromagnets within a nonequilibrium spintronic device

A. Suresh, R. D. Soares, P. Mondal +6

Using the nascent concept of quantum spin-transfer torque [A. Zholud et al., Phys. Rev. Lett. {\bf 119}, 257201 (2017); M. D. Petrović {\em et al.}, Phys. Rev. X {\bf 11}, 021062 (…

Robust band of critical states in T broken fermionic systems with lattice selective disorder

Eduardo V. Castro, Raphael de Gail, M. Pilar López-Sancho +1

We analyze the localization properties of two dimensional systems based on partite lattices with a basis. Contrary to standard results, we find that a band of critical states emerg…

Temperature-driven gapless topological insulator

Miguel Gonçalves, Pedro Ribeiro, Rubem Mondaini +1

We investigate the phase diagram of the Haldane-Falicov-Kimball model -- a model combining topology, interactions and spontaneous disorder at finite temperatures. Using an unbiased…

Spinflop transition in dopped antiferromagnets

N. M. R. Peres

In this paper we compute the mean field phase diagram of a doped antiferromagnet, in a magnetic field and with anisotropic exchange. We show that at zero temperature there is a met…

Magnetic and superconducting instabilities in the periodic Anderson model: an RPA stud

N. M. R. Peres, M. A. N. Araujo

We study the magnetic and superconducting instabilities of the periodic Anderson model with infinite Coulomb repulsion U in the random phase approximation. The Neel temperature and…

Spin waves in La_2CuO_4: band structure and correlation effects

N. M. R. Peres, M. A. N. Araujo

We calculate the antiferromagnetic spin wave dispersion in the half-filled (electronic density n=1) Hubbard model for a two-dimensional square lattice, using the random phase appro…

Numerical and Monte Carlo Bethe ansatz method: 1D Heisenberg model

Shi-Jian Gu, N. M. R. Peres, You-Quan Li

In this paper we present two new numerical methods for studying thermodynamic quantities of integrable models. As an example of the effectiveness of these two approaches, results f…

Spin wave dispersion in La2CuO4

N. M. R. Peres, M. N. Araujo

We calculate the antiferromagnetic spin wave dispersion in the half-filled Hubbard model for a two-dimensional square lattice and find it to be in excellent agreement with recent h…

Specific Heat of the Periodic Anderson Model: From Weak to Strong Coupling

N. M. R. Peres, P. D. Sacramento, M. A. N. Araujo

We study the temperature dependence of the specific heat in the periodic Anderson model as function of the on-site Coulomb interaction, hybridization, and position of the f-electro…
