Transitionless quantum drivings for the harmonic oscillator
J. G. Muga, X. Chen, Ibáñez +2
Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm…

Fast optimal frictionless atom cooling in harmonic traps
Xi Chen, A. Ruschhaupt, S. Schmidt +3
A method is proposed to cool down atoms in a harmonic trap without phase-space compression as in a perfectly slow adiabatic expansion, i.e., keeping the populations of the instanta…
