Fragmentation Experiment and Model for Falling Mercury Drops
P. M. C. de Oliveira, C. A. F. Leite, C. V. Chianca +2
The experiment consists of counting and measuring the size of the many fragments observed after the fall of a mercury drop on the floor. The size distribution follows a power-law f…
Casimir bag energy in the stochastic approximation to the pure QCD vacuum
C. D. Fosco, L. E. Oxman
We study the Casimir contribution to the bag energy coming from gluon field fluctuations, within the context of the stochastic vacuum model (SVM) of pure QCD. After formulating the…
Elastic Scattering and Total Reaction Cross Section for the 6He + 27Al System
E. A. Benjamim, A. Lepine-Szily, D. R. Mendes Junior +14
The elastic scattering of the radioactive halo nucleus 6He on 27Al target was measured at four energies close to the Coulomb barrier using the RIBRAS (Radioactive Ion Beams in Braz…
Two-Dimensional Order and Disorder Thermofields
L. V. Belvedere
The main objective of this paper was to obtain the two-dimensional order and disorder thermal operators using the Thermofield Bosonization formalism. We show that the general prope…
Hf defects in HfO2/Si
W. L. Scopel, Antonio J. R. da Silva, A. Fazzio
We investigate the possibility that Hf defects exist in the Si channel of HfO2 Si-based metal-oxide-semiconductor devices. We have studied, using ab initio Density Functional Theor…
Experimental observation of quantum entanglement in low dimensional spin systems
T. G. Rappoport, L. Ghivelder, J. C. Fernandes +2
We report macroscopic magnetic measurements carried out in order to detect and characterize field-induced quantum entanglement in low dimensional spin systems. We analyze the pyrob…
