A remarkable effect related to the dimensionality of the system occurs in the spectrum of three-boson systems in the universal limit of short-range interactions when passing from three (3D) to two (2D) dimensions. In this case, for a two-body energy (E_2) equal zero, the infinite number of three-body bound states, which comes as a consequence of the Efimov effect, disappears because in 2D...

We present the observation of two consecutive heteronuclear Efimov resonances in an ultracold Fermi-Bose mixture of Li-Cs by measuring magnetic field dependent three-body loss coefficients and atom loss spectra near a broad Feshbach resonance. The first Efimov resonance is found at a scattering length of a(0)=-320(10)a0, corresponding to approximately 7(3) times the Li-Cs (Cs-Cs) van der Waals...

Recent progress in creation of ultra-slow anti-protons, p ̄, [1] is of considerable scientific interest, because of possible formation of low-energy anti-hydrogen atoms H ̄: a bound state of p ̄ and a positron e+. The main goal of the anti-hydrogen/antimatter research is to check and confirm (or not confirm) certain fundamental laws and theories of modern physics. For example, one of the most...

We present some results for pairing in nuclear matter using a relativistic formalism investigating its density dependence, and also how the singlet pairing state changes with temperature for some spherical and deformed nuclei. We will discuss some astrophysical implications of these results, namely the pairing of neutron in the singlet and triplet states, which reduces the neutrino emission...
