Long-wavelength nonequilibrium concentration fluctuations induced by the Soret effect

Light scattering from nonequilibrium concentration fluctuations in a polymer solution

Nonequilibrium fluctuation-induced Casimir pressures in liquid mixtures.

In this article we derive expressions for Casimir-like pressures induced by nonequilibrium concentration fluctuations in liquid mixtures. The results are then applied to liquid mixtures in which the concentration gradient results from a temperature gradient through the Soret effect. A comparison is made between the pressures induced by nonequilibrium concentration fluctuations in liquid mixture...

Nonequilibrium Casimir-like Forces in Liquid Mixtures.

In this Letter, we consider a liquid mixture confined between two thermally conducting walls subjected to a stationary temperature gradient. While in a one-component liquid nonequilibrium fluctuation forces appear inside the liquid layer, nonequilibrium fluctuations in a mixture induce a Casimir-like force on the walls. The physical reason is that the temperature gradient induces large concentr...

The Electron Stopper Layer Effect on Long-Wavelength VCSEL with AsSb-Based DBR Temperature Distribution

In this study, we have theoretically investigated the effect of electron stopper layer on internal temperature distribution of high performance vertical cavity surface-emitting laser emitting at 1305 nm. Simulation software PICS3D, which self-consistently combines the 3D simulation of carrier transport, self-heating, gain computation and wave-guiding, was used. Simulation results show that chan...

Violation of the action-reaction principle and self-forces induced by nonequilibrium fluctuations.

We show that the extension of Casimir-like forces to fluctuating fluids driven out of equilibrium can exhibit two interrelated phenomena forbidden at equilibrium: self-forces can be induced on single asymmetric objects and the action-reaction principle between two objects can be violated. These effects originate in asymmetric restrictions imposed by the objects' boundaries on the fluid's fluctu...
