A 13 Year Black Hole Microlensing Survey in Omega Centauri
Zack Freeman, Maximilian Häberle, Anil Seth +11
Star clusters are born with massive stars that leave behind a large population of stellar mass black holes. These black holes may account for a large fraction of binary black hole…
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…
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…
Numerical Simulations of 3D Ion Crystal Dynamics in a Penning Trap using the Fast Multipole Method
John Zaris, Wes Johnson, Athreya Shankar +2
We simulate the dynamics, including laser cooling, of 3D ion crystals confined in a Penning trap using a newly developed molecular dynamics-like code. The numerical integration of…
Rapid cooling of the in-plane motion of two-dimensional ion crystals in a Penning trap to millikelvin temperatures
Wes Johnson, Athreya Shankar, John Zaris +2
We propose a highly feasible technique with no experimental overhead to rapidly cool the in-plane degrees of freedom of large two-dimensional ion crystals in Penning traps. Through…
Constraining Black Hole Populations in Globular Clusters using Microlensing: Application to Omega Centauri
John Zaris, Doğa Veske, Johan Samsing +3
We estimate the rate of gravitational microlensing events of cluster stars due to black holes (BHs) in the globular cluster NGC 5139 (). Theory and observations both indicate…
