“…1 There the Lewis-Riesenfeld invariants were used to inverse engineer the time dependence of a harmonic oscillator frequency between predetermined initial and final values so as to avoid final excitations. That paper and its companion on Bose-Einstein condensates (Muga et al, 2009) have indeed triggered a surge of activity, not only for harmonic expansions (Chen and Muga, 2010;Muga et al, 2010;Stefanatos et al, 2010;Schaff et al, 2010Schaff et al, , 2011adel Campo, 2011a;Schaff et al, 2011b;Stefanatos et al, 2011;Torrontegui et al, 2012c;Fasihi et al, 2012;Torrontegui et al, 2012a;del Campo and Boshier, 2012;Stefanatos and Li, 2012), but for atom transport (Torrontegui et al, 2011(Torrontegui et al, , 2012dChen et al, 2011b;Bowler et al, 2012), quantum computing (Sarandy et al, 2011), quantum simulations (Lau and James, 2012), optical lattice expansions (Yuce, 2012;Ozcakmakli and Yuce, 2012), wavepacket splitting (Torrontegui et al, 2012b), internal state control (Chen et al, 2011a;Ibáñez et al, 2011;Ruschhaupt et al, 2012;Ban et al, 2012;Ibáñez et al, 2012a;Güngördü et al, 2012), many-body state engineering (del Campo, 2011b;del Campo and Boshier, 2012;Juliá-Díaz et al, 2012), and other applications such as sympathetic cooling of atomic mixtures (Choi, Onofrio and Sundaram, 2011;Choi et al, 2012), or cooling of nanomechanical resonators ...…”
