Quantum-classical correspondence and obstruction to dispersion on the
Engel group
In this paper, we develop the semiclassical analysis of the lowest dimensional simply connected nilpotent Lie group of step 3, called the Engel group and denoted by ${\mathbb E}$, in the continuity of the works for groups of step 2 realized and exhibiting new features specific to groups of higher …
