Probing Mermin's inequalities violations through pseudospin operators
Philipe De Fabritiis, Itzhak Roditi, Silvio P. Sorella
The violation of Mermin's inequalities is analyzed by making use of two different Bell setups built with pseudospin operators. Employing entangled states defined by means of squeez…
On the representations of Bell's operators in Quantum Mechanics
Silvio Paolo Sorella
We point out that, when the dimension of the Hilbert space is greater than two, Bell's operators entering the Bell-CHSH inequality exhibit unitarily inequivalent representations. A…
Entangled coherent states and violations of Bell-CHSH inequalities
Philipe De Fabritiis, Fillipe M. Guedes, Giovani Peruzzo +1
Three classes of entangled coherent states are employed to study the Bell-CHSH inequality. By using pseudospin operators in infinite dimensional Hilbert spaces, four dichotomic ope…
Noncommutative Derivation of the Planck's Radiation Law
M. A. De Andrade, L. G. Ferreira Filho, C. Neves
The Planck's radiation law for the blackbody radiation spectrum was capable to explain the experimentally-measured blackbody spectrum. In order to get this result, Planck proposed…
Entanglement and maximal violation of the CHSH inequality in a system of two spins j: a novel construction and further observations
Giovani Peruzzo, Silvio Paolo Sorella
We study the CHSH inequality for a system of two spin particles, for generic . The CHSH operator is constructed using a set of unitary, Hermitian operators $\left\{ A_{1},A_…
Comments on the Bell-Clauser-Horne-Shimony-Holt inequality
S. P. Sorella
We discuss the relationship between the Bogoliubov transformations, squeezed states, entanglement and maximum violation of the Bell-CHSH inequality. In particular, we point out tha…
