  Shortcuts to adiabaticity (STA) provide an alternative to adiabatic protocols
to guide the dynamics of the system of interest without the requirement of slow
driving. We report the controlled speedup via STA of the nonadiabatic dynamics
of a Fermi gas, both in the non-interacting and strongly coupled, unitary
regimes. Friction-free superadiabatic expansion strokes, with no residual
excitations in the final state, are demonstrated in the unitary regime by
engineering the modulation of the frequencies and aspect ratio of the harmonic
trap. STA are also analyzed and implemented in the high-temperature regime,
where the shear viscosity plays a pivotal role and the Fermi gas is described
by viscous hydrodynamics.
