Query: Freezing a Quantum Magnet by Repeated Quantum Interference: An
  Experimental Realization   We experimentally demonstrate the phenomenon of dynamical many-body freezing
in a periodically driven Ising chain. Theoretically [Phys. Rev. B 82, 172402
(2010)], for certain values of the drive parameters all fundamental degrees of
freedom contributing to the response dynamics freeze for all time and for
arbitrary initial states. Also, since the condition of freezing involves only
the drive parameters and not on the quantization of the momentum (i.e., the
system-size), our simulation with a small (3-spin) chain captures all salient
features of the freezing phenomenon predicted for the infinite chain. Using
optimal control techniques, we realize high-fidelity cosine modulated drive,
and observe non-monotonic freezing of magnetization at specific frequencies of
modulation. Time-evolution of the excitations in momentum space has been
tracked directly through magnetization measurements.
