KW - adiabatic process, atom cooling, quantum harmonic oscillator.
AB - <p style="text-align: justify;">We review the methods to preserve the initial state populations in a fast harmonic trap expansion. The design of the time dependence of the frequency using inverse techniques presents advantages over the slow adiabatic approach,
band-bang methods, or the non-local &quot;transitionless tracking&#39;&#39; algorithm.
Many operations with cold atoms make use of adiabatic expansions and would benefit from such a shortcut to adiabaticity.</p>
