Normalization procedure for relaxation studies in NMR quantum information processing
A. Gavini-Viana, A. M. Souza, D. O. Soares-Pinto +5
NMR quantum information processing studies rely on the reconstruction of the density matrix representing the so-called pseudo-pure states (PPS). An initially pure part of a PPS sta…
Finite size analysis of a two-dimensional Ising model within a nonextensive approach
N. Crokidakis, D. O. Soares-Pinto, M. S. Reis +3
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…
Entanglement temperature in molecular magnets composed of S-spin dimers
D. O. Soares-Pinto, A. M. Souza, R. S. Sarthour +5
In the present work, we investigate the quantum thermal entanglement in molecular magnets composed of dimers of spin , using an Entanglement Witness built from measurements of m…
Entanglement and Bell's inequality violation above room temperature in metal carboxylates
A. M. Souza, D. O. Soares-Pinto, R. S. Sarthour +4
In the present work we show that a special family of materials, the metal carboxylates, may have entangled states up to very high temperatures. From magnetic susceptibility measure…
