Bipartite entanglement via distance between the states in a one dimensional spin 1/2 dimer copper acetate monohydrate
S. Athira, Saulo L. L. Silva, Sushma Lakshmi +8
In this paper, we used a theoretical measure known as distance between the states, , to determine the bipartite entanglement of a one dimensional magnetic dimer s…
Impurity-induced increase in the thermal quantum correlations and teleportation in an Ising-XXZ diamond chain
Saulo L. L. Silva, Moises Rojas
In this work we analyze the quantum correlations in a spin-1/2 Ising-XXZ diamond chain with one plaquette distorted impurity. We have shown that the introduction of impurity into t…
The Hilbert-Schmidt norm as a measure of entanglement in spin-1/2 Heisenberg chain: generalized Bell inequality and distance between states
Saulo L L da Silva, Daniel H. T. Franco
In this letter, we show that the measure of entanglement using the generalized Bell inequality and the distance between states coincide when we use the Hilbert-Schmidt norm. Our co…
Thermal entanglement in Heisenberg chains via distance between states
Saulo Luis Lima da Silva
Most of the work involving entanglement measurement focuses on systems that can be modeled by two interacting qubits. This is due to the fact that there are few studies presenting…
