Numerical modeling for trapped-ion thermometry using dark resonances
Muriel Bonetto, Nicolás Adrián Nuñez Barreto, Christian Tomás Schmiegelow +1
The simulation of vibrational energy transport and quantum thermodynamics with trapped ions requires good methods for the estimation of temperatures. One valuable tool for this pur…
Observation of Space-Dependent Rotational Doppler Shifts with a Single Ion Probe
Nicolás Adrián Nuñez Barreto, Muriel Bonetto, Marcelo Alejandro Luda +2
We present an experiment investigating the rotational Doppler effect using a single trapped ion excited by two copropagating vortex laser beams. The setup isolates the azimuthal gr…
Dark resonance spectra of trapped ions under the influence of micromotion
Nicolás Adrián Nuñez Barreto, Muriel Bonetto, Marcelo Alejandro Luda +2
We study the influence of micromotion on the spectrum of trapped ions with a lambda-type level scheme, leading to dark resonances due to coherent population trapping. We work with…
Transient fluorescence with a single trapped ion
Nicolás Nuñez Barreto, Lucas Giardino, Carla Crucianelli +3
In this paper we present a method to measure transient fluorescent dynamics with single trapped ions in a Paul trap. We use Ca ions which exhibit a -type three-level…
