Controlling the quantum rotational dynamics of a driven planar rotor by rebuilding barriers in the classical phase space

Dynamical Tunneling in More than Two Degrees of Freedom

“…In beam-beam interactions (13), there is the problem of having to remain as close as possible to given computed orbits in order to indeed have interaction between particles. Within the old and not-yet-solved problem of the stability of the solar system, it is not completely clear whether the orbits of some planets (14 ) and of a significant number of asteroids (15) will change or not in an important way. Previous work has been based on numerical applications of the frequency-map analysis (16 ).…”

“…In the molecular context, examples come from high-resolution spectra wherein "clumps" of spectral lines are associated with the vibrational superexchange mechanism [4,5] and related to quantum vibrational energy flow in molecules [6][7][8]. Additional examples include the generation of NOON states in ultracold bosonic atoms [9,10], the efficacy of coherent control in driven [11][12][13][14] and kicked [15,16] systems, stability of quantum discrete breathers [17,18], and fragmentation of trapped Bose-Einstein condensates [19,20]. Furthermore, dynamical tunneling has been shown to play a crucial role in a variety of "engineered" systems [21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”
