Verification of a many-ion simulator of the Dicke model through slow quenches across a phase transition
A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7
We use a self-assembled two-dimensional Coulomb crystal of ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…

Quenches near criticality of the quantum Ising chain---power and limitations of the discrete truncated Wigner approximation
Stefanie Czischek, Martin Gärttner, Markus Oberthaler +2
The semi-classical discrete truncated Wigner approximation (dTWA) has recently been proposed as a simulation method for spin- systems. While it appears to provide a powerful a…
