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…
Resolutions of ideals of fat points with support in a hyperplane
Giuliana Fatabbi, Brian Harbourne, Anna Lorenzini
Our results concern minimal graded free resolutions of fat point ideals for points in a hyperplane. Suppose, for example, that I(m,d) is the ideal defining r given points of multip…
EVN Observations of the BL Lac object ON 231
F. Mantovani, E. Massaro, R. Fanti +3
New EVN images at 5.0 GHz and 8.4 GHz of ON 231 confirm the complex structure of the source, the identification of the core, the presence of components on the two sides of the core…
A quantum duality principle for coisotropic subgroups and Poisson quotients
Nicola Ciccoli, Fabio Gavarini
We develop a quantum duality principle for coisotropic subgroups of a (formal) Poisson group and its dual. Namely, starting from a quantum coisotropic subgroup (for a quantization…
