Non-equilibrium dynamics of Ising models with decoherence: an exact solution
Michael Foss-Feig, Kaden R. A. Hazzard, John J. Bollinger +1
The interplay between interactions and decoherence in many-body systems is of fundamental importance in quantum physics: Decoherence can degrade correlations, but can also give ris…
Relaxation timescales and decay of correlations in a long-range interacting quantum simulator
Mauritz van den Worm, Brian C. Sawyer, John J. Bollinger +1
We study the time evolution of correlation functions in long-range interacting quantum Ising models. For a large class of initial conditions, exact analytic results are obtained in…
Engineered 2D Ising interactions on a trapped-ion quantum simulator with hundreds of spins
Joseph W. Britton, Brian C. Sawyer, Adam C. Keith +5
The presence of long-range quantum spin correlations underlies a variety of physical phenomena in condensed matter systems, potentially including high-temperature superconductivity…
Spectroscopy and Thermometry of Drumhead Modes in a Mesoscopic Trapped-Ion Crystal using Entanglement
Brian C. Sawyer, Joseph W. Britton, Adam C. Keith +5
We demonstrate spectroscopy and thermometry of individual motional modes in a mesoscopic 2D ion array using entanglement-induced decoherence as a method of transduction. Our system…
