Query: Bang-bang shortcut to adiabaticity in the Dicke model as realized in a
  Penning trap experiment   We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which
we implement via a 2-D array of trapped ions in a Penning trap with a
spin-dependent force detuned close to the center-of-mass drumhead mode. Our
focus is on employing this shortcut to create highly entangled states that can
be used in high-precision metrology. We highlight that the performance of the
bang-bang approach is comparable to standard preparation methods, but can be
applied over a much shorter time frame. We compare these theoretical ideas with
experimental data which serve as a first step towards realizing this
theoretical procedure for generating multi-partite entanglement.
