Nonlinear Oscillator with a Single Trapped Ion — •Moritz Göb, Bo Deng, Max Masuhr, Kilian Singer, and Daqing Wang — Experimentalphysik I, Universität Kassel, Heinrich-Plett-Straße 40, 34132 Kassel
Nonlinear oscillators are interesting test systems for realizing thermal machines in the quantum regime. In our experiment, we investigate a single, laser-cooled 40Ca+ ion confined in a funnel-shaped Paul trap. This trap geometry leads to an interaction of the axial and radial phonons, which resembles the optomechanical interaction described by the radiation pressure Hamiltonian. Based on this system, we measure and characterize this nonlinear interaction and the resulted mechanical bistability. In this poster, I will detail the technical implementation of this experiment.
