One-dimensional magnetism in synthetic Pauflerite, -VOSO
Diana Lucia Quintero-Castro, Gøran J. Nilsen, Katrin Meier-Kirchner +7
We have synthesized single-crystal samples of -VOSO and fully characterized their magnetic properties. Our magnetic susceptibility, high field magnetization and powder inela…
Quantum-well states at the surface of the heavy-fermion superconductor URuSi
Edwin Herrera-Vasco, Isabel Guillamón, Víctor Barrena +10
Electrons can form a two-dimensional electron gas at metal surfaces, where lateral confinement leads to quantum-well states. Such states have been observed for highly itinerant ele…
The cumulant Green's functions method for the Hubbard model
Renan Lira, Peter Riseborough, Jereson Silva-Valencia +1
We study the single-band Hubbard model under the action of an external magnetic field using the cumulant Green's functions method (CGFM). The starting point of the method is to dia…
Mass imbalance in the ionic Hubbard model: a DRMG study
D. C. Padilla-González, R. Franco, J. Silva-Valencia
We investigated the ionic Hubbard model with mass imbalance in one dimension, using the density matrix renormalization group method. This model exhibits a band insulator phase and…
Anomalous Magnetism for Dirac Electrons in Two Dimensional Rashba Systems
H. Vivas
Spin-spin correlation function response in the low electronic density regime and externally applied electric field is evaluated for 2D metallic crystals under Rashba-type coupling,…
Quantum anisotropic Heisenberg chains with superlattice structure: a DMRG study
J. Silva-Valencia, J. C. Xavier, E. Miranda
Using the density matrix renormalization group technique, we study spin superlattices composed of a repeated pattern of two spin-1/2 XXZ chains with different anisotropy parameters…
