Steady state entanglement in the mechanical vibrations of two dielectric membranes
Physical 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.

Modelling and simulations of reactor neutron noise induced by mechanical vibrations
Annals of Nuclear Energy, 2022 Mechanical vibrations of core internals are among the main perturbations that induce oscillations in the neutron flux field, also known as neutron noise. In this work, different simulation models for the study of the influence of the mechanical vibrations ...

Exploring Fatigue Effects on Performance Variation of Intensive Brain–Computer Interface Practice
Frontiers in Neuroscience, 2021 Motor imagery (MI) is an endogenous mental process and is commonly used as an electroencephalogram (EEG)-based brain–computer interface (BCI) strategy. Previous studies of P300 and MI-based (without online feedback) BCI have shown that mental states like

Grey-box state-space identification of nonlinear mechanical vibrations [PDF]
International Journal of Control, 2018 The present paper deals with the identification of nonlinear mechanical vibrations. A grey-box, or semi-physical, nonlinear state-space representation is introduced, expressing the nonlinear basis functions using a limited number of measured output ...
