The silicon microring resonator is a superb platform for both fundamental studies and practical applications of various nonlinear optic phenomena.However, the highly enhanced light intensity rawafricaonline.com in the ring cavity makes it quite sensitive to thermal variations and can in turn incur detrimental instability or degradation to the concu
We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under various geometrical constraints such as flat walls, spherical obstacles and cylindrical cavities.We observe that the main effect of the confined viscoelastic fluid is to induce an effective repulsion on the APs when moving whelen arges spotlight close to a
