A three-modes Kuramoto network in a single nonlinear microelectromechanical device

This work presents a frequency multiplexed 3-limit cycles network in a multimode microelectromechanical nonlinear resonator. The network is composed of libration limit cycles and behaves in an analogous manner to a phase oscillator network. The libration limit cycles interact wit...

Optimizing entanglement manipulation via algebraic–geometric decompositions and semi-definite programming hierarchies

In the study of distributed quantum information processing, it is a fundamental problem to optimize local operations in the implementation of non-local quantum operations assisted by limited entanglement. We develop an algebraic–geometric framework that systematically simplifies...

Skin displacement and velocity contribute to perception of force direction: insights from illusory tactile pulling sensations

Abstract Humans perceive tangential force at the fingertip through skin deformation characterized by kinematic components, such as displacement, velocity and acceleration. However, their respective contributions to the perception remain unclear because these components typically...
