Majorana transformation for differential equations
Salvatore Esposito
We present a method for reducing the order of ordinary differential equations satisfying a given scaling relation (Majorana scale-invariant equations). We also develop a variant of…
A detailed analysis of the neutron to proton ratio at the onset of primordial nucleosynthesis
S. Esposito, G. Mangano, G. Miele +1
We report on the results of a recent evaluation of all percent level corrections to weak rates of processes converting n <-> p, which are crucial for the determination of the 4He m…
Primordial Nucleosynthesis: accurate predictions for light element abundances
S. Esposito
A detailed analysis of primordial nucleosynthesis predictions for light element abundances is performed. Contents: 1. The standard cosmology: an overview. 2. Primordial nucleosynth…
On the role of Spin in Quantum Mechanics
S. Esposito
From the invariance properties of the Schrodinger equation and the isotropy of space we show that a generic (non-relativistic) quantum system is endowed with an ``external'' motion…
