The nuclear and Coulomb breakup of the weakly bound Li with targets in the range from A = 59 to 208
D. R. Otomar, P. R. S. Gomes, J. Lubian +2
We have performed CDCC calculations for the Li + Co, Sm and Pb systems, to investigate the dependence of the relative importance of nuclear and Coulomb…
Invariance of the fine structure constant with temperature of the expanding universe
Claudio Nassif, A. C. Amaro de Faria
Our goal is to interpret the energy equation from Doubly Special Relativity (DSR) of Magueijo-Smolin with an invariant Planck energy scale in order to obtain the speed of light wit…
Torsion in the crystalline cohomology of singular varieties
Bhargav Bhatt
This note discusses some examples showing that the crystalline cohomology of even very mildly singular projective varieties tends to be quite large. In particular, any singular pro…
Variation of the speed of light with temperature of the expanding universe
Cláudio Nassif Cruz, Antônio Carlos Amaro de Faria
From an extended relativistic dynamics for a particle moving in a cosmic background field with temperature T, we aim to obtain the speed of light with an explicit dependence on the…
