Data for Ultrahigh Quality Factor of a Levitated Nanomechanical Oscillator
<p>A levitated nanomechanical oscillator under ultra-high vacuum (UHV) is highly isolated from<br>its environment. It has been predicted that this isolation leads to very low mechanical dissipation<br>rates. However, a gap persists between predictions and experimental data. Here, we levitate a silica<br>nanoparticle in a linear Paul trap at room temperature, at pressures as low as 7 × 10−11 mbar. We<br>measure a dissipation rate of 2π ×69(22) nHz, corresponding to a quality factor exceeding 1010, more<br>than two orders of magnitude higher than previously shown. A study of the pressure dependence of<br>the particle’s damping and heating rates provides insight into the relevant dissipation mechanisms.</p>

Position Measurement of a Levitated Nanoparticle via Interference with Its Mirror Image
<p>Interferometric methods for detecting the motion of a levitated nanoparticle provide a route to the quantum ground state, but such methods are currently limited by mode mismatch between the reference beam and the dipolar field scattered by the particle. Here we demonstrate a self-interference method to detect the particle’s motion that solves this problem. A Paul trap confines a charged dielectric nanoparticle in high vacuum, and a mirror retro-reflects the scattered light. We measure the particle’s motion with a sensitivity of 1.7×10−12  m/√Hz, corresponding to a detection efficiency of 2.1%, with a numerical aperture of 0.18. As an application of this method, we cool the particle, via feedback, to temperatures below those achieved in the same setup using a standard position measurement.</p>

Transcription profiling of Drosophila exposed to a levitation magnet for different lengths of time
Drosophila samples were exposed to the levitation magnet inside a 25mm diameter tubes with 3 ml of yeast-based Drosophila food in the bottom and a chamber of only 5 mm of height over the food. This small region is needed in order to guarantee that all the flies were located in the effective g area so a maximum of 35 to 40 imagos or pupa can be exposed to each condition per experiment. All experiments were carried out with a parallel 1g external control in a temperature regulated incubator outside the magnet. Three experiments of different duration were performed inside the magnet system to analyze the effect of strong magnetic fields and magnetic levitation during different stages of the Drosophila development
