Theoretical study of the exchange coupling in a Ni12 single-molecule magnet
(2006)
The exchange interactions in a Ni12 complex have been studied by using theoretical methods based on density functional theory. The calculated J values reproduce correctly the S = 12 ground state of this system found ...
Understanding the mechanisms of nuclear collisions: A complete study of the B 10 + Sn 120 reaction
(American Physical Society, 2021-03)
Background: Reactions involving exotic and stable weakly bound nuclei have been extensively studied in recent years. Although several models have been successfully used to explain particular reaction outcomes, the answers ...
Experimental study of the reaction 6Li + 154Sm at 7 MeV/u using the Saci-Pererê spectrometer
(2016)
Abstract. In this work we analyze experimental data of the nuclear reaction between 6 3Li + 154 62Sm . The experimental data come from the gamma-particle coincidence experimental technique using Saci-Pererê γ-ray ...
Magnetic excitations of perovskite rare-earth nickelates: RNiO3
(Elsevier Science, 2015-06)
To gain insight into the ground state of perovskite nickelates RNiO3 (R: rare-earth), in particular charge disproportionation of the Ni ions and the magnetic configuration, we studied the magnetic excitations of the ...
RVB signatures in the spin dynamics of the square-lattice Heisenberg antiferromagnet
(IOP Publishing, 2016-03)
We investigate the spin dynamics of the square-lattice spin- 1/2 Heisenberg antiferromagnet by means of an improved mean-field Schwinger boson calculation. By identifying both, the long-range Neel and the RVB-like components ...
The vibrational spectrum and ultimate modulus of polyethylene
(Amer Chemical Soc Inc, 2006-08-03)
We have performed the first completely ab initio lattice dynamics calculation of the full orthorhombic cell of polyethylene using periodic density functional theory in the local density approximation (LDA) and the generalized ...
