Tuning the thermal entanglement in a Ising- diamond chain with two impurities
I. M. Carvalho, O. Rojas, S. M. de Souza +1
We study the local thermal entanglement in a spin-1/2 Ising- diamond structure with two impurities. In this spin chain, we have the two impurities with an isolated dimer…

Correlation functions for a spin- Ising-XYZ diamond chain: Further evidence for quasi-phases and pseudo-transitions
I. M. Carvalho, J. Torrico, S. M. de Souza +2
One-dimensional systems with short-range interactions cannot exhibit a long-range order at nonzero temperature. However, there are some particular one-dimensional models, such as t…
