Intrinsic phonon effects on analog quantum simulators with ultracold trapped ions
C. -C. Joseph Wang, J. K. Freericks
Linear Paul traps have been used recently to simulate the transverse field Ising model with long-range spin-spin couplings. We study the intrinsic effects of phonon creation (from…

Disentangling phonons from spins in ion-trap-based quantum spin simulators
C. -C. Joseph Wang, James Freericks
We compute how phonon creation affects the fidelity of the quantum spin dynamics in trapped ion simulators. A rigorous treatment of the quantum dynamics is made by employing an exa…

Quantum vortex dynamics in two-dimensional neutral superfluids
C. -C. Joseph Wang, R. A. Duine, A. H. MacDonald
We derive an effective action for the vortex position degree-of-freedom in a superfluid by integrating out condensate phase and density fluctuation environmental modes. When the qu…
