Vibrational Effect on Entropy Generation in a Square Porous Cavity [PDF]
Entropy, 2003 : We investigate the nature of entropy generation for natural convection in a two-dimensional square section enclosure vibrating sinusoidally perpendicular to the applied temperature gradient in a zero-gravity field. The enclosure is assumed to fill with

Enhanced collective Purcell effect of coupled quantum emitter systems [PDF]
Phys. Rev. A 99, 043843 (2019), 2018 Cavity-embedded quantum emitters show strong modifications of free space radiation properties such as an enhanced decay known as the Purcell effect. The central parameter is the cooperativity $C$, the ratio of the square of the coherent cavity coupling strength over the product of cavity and emitter decay rates. For a single emitter, $C$ is independent

Cavity cooling of an optically trapped nanoparticle [PDF]
, 2009 We study the cooling of a dielectric nanoscale particle trapped in an optical cavity. We derive the frictional force for motion in the cavity field, and show that the cooling rate is proportional to the square of oscillation amplitude and frequency. Both the radial and axial centre-of-mass motion of the trapped particle, which are coupled by the cavity

Exothermic chemical reaction of magneto-convective nanofluid flow in a square cavity
International Journal of Thermofluids, 2022 We investigate the unsteady laminar convective magnetohydrodynamic nanofluids flow in a square cavity driven by an exothermic chemical reaction. Because exothermic chemical reactions are intrinsic in nanofluidic flow applications, we consider this ...
