Penning-trap eigenfrequency measurements with optical radiofrequency detectors
Joaquín Berrocal, Alejandro Hernández, Íñigo Arrazola +5
We use an electric-dipole laser-driven transition to precisely measure the cyclotron-frequency ratios of the pairs Ca-Ca, Ca-Ca and $^{4…
A Coupled-Oscillators Model to Analyze the Interaction between a Quartz Resonator and Trapped Ions
Emilio Altozano, Joaquín Berrocal, Steffen Lohse +4
The novel application of a piezoelectric quartz resonator for the detection of trapped ions has developed in the observation of the quartz-ions interaction under non-equilibrium co…
Formation of Two-Ion Crystals by Injection from a Paul-Trap Source into a High-Magnetic-Field Penning Trap
Joaquín Berrocal, Emilio Altozano, Francisco Domínguez +6
Two-ion crystals constitute a platform for investigations of quantum nature that can be extended to any ion species or charged particle provided one of the ions in the crystal can…
Production of Fock Mixtures in Trapped Ions for Motional Metrology
Antonis Delakouras, Daniel Rodríguez, Javier Cerrillo
We present a protocol to produce a class of non-thermal Fock state mixtures in trapped ions. This class of states features a clear metrological advantage with respect to the ground…
Dynamics of an unbalanced two-ion crystal in a Penning trap for application in optical mass spectrometry
Manuel J. Gutiérrez, Joaquín Berrocal, Francisco Domínguez +4
In this article, the dynamics of an unbalanced two-ion crystal comprising the 'target' and the 'sensor' ions confined in a Penning trap has been studied. First, the low amplitude r…
