Tolerance Relations and Quantization
Francesco D'Andrea, Giovanni Landi, Fedele Lizzi
It is well known that "bad" quotient spaces (typically: non-Hausdorff) can be studied by associating to them the groupoid C*-algebra of an equivalence relation, that in the "nice"…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Photometry and model of near-Earth asteroid 2021 DW1 from one apparition
T. Kwiatkowski, P. Koleńczuk, A. Kryszczyńska +17
On 4 March 2021 at 9 UTC a 30-m in diameter near-Earth asteroid 2021 DW1 passed the Earth at a distance of 570000 km, reaching the maximum brightness of V=14.6 mag. We observed it…
REST-for-Physics, a ROOT-based framework for event oriented data analysis and combined Monte Carlo response
Konrad Altenmüller, Susana Cebrián, Theopisti Dafni +19
The REST-for-Physics (Rare Event Searches Toolkit for Physics) framework is a ROOT-based solution providing the means to process and analyze experimental or Monte Carlo event data.…
Nambu-Covariant Many-Body Theory II: Self-Consistent Approximations
M. Drissi, A. Rios, C. Barbieri
The theory of Self-Consistent Green's Function (SCGF) is reformulated in an explicit Nambu-covariant fashion for applications to many-body systems at non-zero temperature in symmet…
Nambu-Covariant Many-Body Theory I: Perturbative Approximations
M. Drissi, A. Rios, C. Barbieri
Symmetry-breaking considerations play an important role in allowing reliable and accurate predictions of complex systems in quantum many-body simulations. The general theory of per…
