A semiclassical tetrahedron. (English) Zbl 1107.83026
Summary: We construct a macroscopic semiclassical state for a quantum tetrahedron. The expectation values of the geometrical operators representing the volume, areas and dihedral angles are peaked around assigned classical values, with vanishing relative uncertainties.
