Query: Motional $N$-phonon Bundle States of A Trapped Atom with Clock
  Transitions   Quantum manipulation of individual phonons could offer new resources for
studying fundamental physics and creating an innovative platform in quantum
information science. Here, we propose to generate quantum states of strongly
correlated phonon bundles associated with the motion of a trapped atom. Our
scheme operates in the atom-phonon resonance regime where the energy spectrum
exhibits strong anharmonicity such that energy eigenstates with different
phonon numbers can be well-resolved in the parameter space. Compared to earlier
schemes operating in the far dispersive regime, the bundle states generated
here contain a large steady-state phonon number. Therefore, the proposed system
can be used as a high quality multiphonon source. Our results open up the
possibility of using long-lived motional phonons as quantum resources, which
could provide a broad physics community for applications in quantum metrology.
