Steady State Entanglement in the Mechanical Vibrations of Two Dielectric Membranes [PDF]

open access: yesPhysical Review Letters, 2008
We consider two dielectric membranes suspended inside a Fabry-Perot-cavity, which are cooled to a steady state via a drive by suitable classical lasers. We show that the vibrations of the membranes can be entangled in this steady state.

Suppression of rotating machine shaft-line torsional vibrations by a driving asynchronous motor using two advanced control methods [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2023
Many industrial rotating machines driven by asynchronous motors are often affected by detrimental torsional vibrations. In this paper, a method of attenuation of torsional vibrations in such objects is proposed.
