Groupoids and the tomographic picture of quantum mechanics
A. Ibort, V. I. Manko, G. Marmo +2
The existing relation between the tomographic description of quantum states and the convolution algebra of certain discrete groupoids represented on Hilbert spaces will be discusse…
Universality of the three-body Efimov parameter at narrow Feshbach resonances
Sanjukta Roy, Manuele Landini, Andreas Trenkwalder +6
We measure the critical scattering length for the appearance of the first three-body bound state, or Efimov three-body parameter, at seven different Feshbach resonances in ultracol…
Realization of associative products in terms of Moyal and tomographic symbols
A. Ibort, V. I. Man'ko, G. Marmo +3
The quantizer-dequantizer method allows to construct associative products on any measure space. Here we consider an inverse problem: given an associative product is it possible to…
