Localized control of large ion crystals in a Penning trap using a spatial light modulator
Allison L. Carter, Jennifer F. Lilieholm, Bryce B. Bullock +3
Penning ion traps as quantum platforms have primarily utilized global control and symmetric Dicke states for quantum simulation and sensing experiments. The introduction of local c…
Optimizing Doppler laser cooling protocols for quantum sensing with 3D ion crystals in a Penning trap
John Zaris, Wes Johnson, Athreya Shankar +4
Large, 3D trapped ion crystals offer improved sensitivity in quantum sensing protocols, and are expected to be implemented as platforms in near-future experiments. However, numeric…
Quantum simulation of the Dicke model in a two-dimensional ion crystal: chaos, quantum thermalization, and revivals
Bryce Bullock, Sean R. Muleady, Jennifer F. Lilieholm +6
Quantum many-body systems driven far from equilibrium can exhibit chaos, entanglement, and non-classical correlations, yet directly observing these phenomena in large, closed quant…
Many-Body Effects in Dark-State Laser Cooling
Muhammad Miskeen Khan, David Wellnitz, Bhuvanesh Sundar +5
We develop a unified many-body theory of two-photon dark-state laser cooling, the workhorse for preparing trapped ions close to their motional quantum ground state. For ions with a…
Adiabatic Cooling of Planar Motion in a Penning Trap Ion Crystal to Sub-Millikelvin Temperatures
Wes Johnson, Bryce Bullock, Athreya Shankar +3
Two-dimensional planar ion crystals in a Penning trap are a platform for quantum information science experiments. However, the low-frequency planar modes of these crystals are not…
Parametric Amplification of Spin-Motion Coupling in Three-Dimensional Trapped-Ion Crystals
Samarth Hawaldar, N. Nikhil, Ana Maria Rey +2
Three-dimensional (3D) crystals offer a route to scale up trapped ion systems for quantum sensing and quantum simulation applications. However, engineering coherent spin-motion cou…
