Black Hole Mass Measurements of Early-Type Galaxies NGC 1380 and NGC 6861 Through ALMA and HST Observations and Gas-Dynamical Modeling

K. M. Kabasares, A. J. Barth, D. A. Buote +6

We present Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 2 observations of CO(2-1) emission from the circumnuclear disks in two early-type galaxies, NGC 1380 and NGC 68…

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 ∼70 ions in the presence of an external transverse field to engineer a simulator of the Dicke Hamiltonian, an iconi…

Bang-bang shortcut to adiabaticity in the Dicke model as realized in a Penning trap experiment

J. Cohn, A. Safavi-Naini, R. J. Lewis-Swan +7

We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a 2-D array of trapped ions in a Penning trap with a spin-dependent force detuned clos…

Exploring adiabatic quantum dynamics of the Dicke model in a trapped ion quantum simulator

A. Safavi-Naini, R. J. Lewis-Swan, J. G. Bohnet +7

We use a self-assembled two-dimensional Coulomb crystal of ∼70 ions in the presence of an external transverse field to engineer a quantum simulator of the Dicke Hamiltonian.…
