Direct experimental evidence of free fermion antibunching
M. Iannuzzi, A. Orecchini, F. Sacchetti +2
Fermion antibunching was observed on a beam of free noninteracting neutrons. A monochromatic beam of thermal neutrons was first split by a graphite single crystal, then fed to two…
Effective construction of irreducible curve singularities
Abdallah Assi, Margherita Barile
We can associate with any irreducible curve singularity (ics) a numerical semigroup. Two ics are said to be equisingular if they have the same semigroup. Two equisingular ics have…
On toric varieties which are almost set-theoretic complete intersections
Margherita Barile
We describe a class of affine toric varieties that are set-theoretically minimally defined by codim binomial equations over fields of any characteristic.
A note on Veronese varieties
Margherita Barile
We show that for every prime , there is a class of Veronese varieties which are set-theoretic complete intersections if and only if the ground field has characteristic .
