Formation of spin and charge ordering in the extended Hubbard model during a finite-time quantum quench
Isaac M. Carvalho, Helena Bragança, Walber H. Brito +1
We investigate the formation of charge and spin ordering by starting from a non-interacting state and studying how it evolves in time under a Hamiltonian with finite electronic int…
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…
Quantum entanglement in the neighborhood of pseudo-transition for a spin-1/2 Ising-XYZ diamond chain
I. M. Carvalho, J. Torrico, S. M. de Souza +2
Recently has been observed for some one-dimensional models that exhibit unexpected pseudo-transitions and quasi-phases. This pseudo-transition resembles a first- and second-order p…
