Crokidakis, N., Soares-Pinto, D. O., Reis, M. S., Souza, A. M., Sarthour, R. S., Oliveira, I. S.
In this work we present a thorough analysis of the phase transitions that occur in a ferromagnetic 2D Ising model, with only nearest-neighbors interactions, in the framework of the Tsallis...
Entanglement temperature in molecular magnets composed of S-spin dimers (2009)
Soares-Pinto, D. O., Souza, A. M., Sarthour, R. S., Oliveira, I. S., Reis, M. S., Brandao, P., ...
In the present work, we investigate the quantum thermal entanglement in molecular magnets composed of dimers of spin $S$, using an Entanglement Witness built from measurements of magnetic...
Souza, A. M., Reis, M. S., Soares-Pinto, D. O., Oliveira, I. S., Sarthour, R. S.
The present work reports an experimental observation of thermal entanglement in a clusterized spin chain formed in the compound Na$_2$Cu$_5$Si$_4$O$_{14}$. The presence of entanglement was...
NMR Analog of Bell's Inequalities Violation Test (2007)
Souza, A. M., Magalhaes, A., Teles, J., DeAzevedo, E. R., Bonagamba, T. J., Oliveira, I. S., ...
In this paper we present an analog of the Bell's inequalities violation test for $N$ qubits to be performed in a nuclear magnetic resonance (NMR) quantum computer. This can be used to simulate or...
DEFECT ANALYSIS IN NATURAL QUARTZ FROM BRAZILIAN SITES FOR IONISING RADIATION DOSIMETRY (2006)
Guzzo, P. L., Khoury, H. J., Souza, C. P., Souza, A. M., Schwartz, M. O. E., Azevedo, W. M.
The impurity-related point defects and the dosimetry properties of quartz irradiated with gamma- and X-rays doses were investigated for natural crystals taken from different geologies. The specimens...
