Quantum point contact conductance in NINS junctions
William J. Herrera, J. Virgilio Niño, J. Jairo Giraldo
The effect of an insulating barrier located at a distance from a NS quantum point contact is analyzed in this work. The Bogoliubov de Gennes equations are solved for NINS junct…
The relation between momentum conservation and Newton's third law revisited
Rodolfo A. Diaz, William J. Herrera
Under certain conditions usually fulfilled in classical mechanics, the principle of conservation of linear momentum and Newton's third law are equivalent. However, the demonstratio…
Using symmetries and generating functions to calculate and minimize moments of inertia
Rodolfo A. Diaz, William J. Herrera, R. Martinez
This paper presents some formulae to calculate moments of inertia for solids of revolution and for solids generated by contour plots. For this, the symmetry properties and the gene…
