The key to explaining and controlling a range of quantum phenomena is to study how information propagates around many-body systems. This quantum dynamics can be described by particle-like carriers of information that emerge in the collective behaviour of the underlying system, so called quasiparticles.
We engineer such quasiparticles in a quantum many-body system of trapped atomic ions, whose interactions are determined by a transverse-field Ising Hamiltonian [1]. In my talk, I will present how we approximately construct the Eigenstates of the system, perform spectroscopy on low lying energy levels and observe signatures of quasiparticle interactions in our system [2].
