Quantum Radiation Properties of Dirac Particles in General Nonstationary Black Holes

open access: yesAdvances in High Energy Physics, 2014
Quantum radiation properties of Dirac particles in general nonstationary black holes in the general case are investigated by both using the method of generalized tortoise coordinate transformation and considering simultaneously the asymptotic behaviors ...

A note on the thermodynamics of gravitational radiation

open access: yes, 2003
It is shown that linearized gravitational radiation confined in a cavity can achieve thermal equilibrium if the mean density of the radiation and the size of the cavity satisfy certain constraints.Comment: 8 pages; discussion expanded and some issues ...

Effects of buoyancy and thermal radiation on MHD flow over a stretching porous sheet using homotopy analysis method

open access: yesAlexandria Engineering Journal, 2015
This paper investigates the theoretical influence of buoyancy and thermal radiation on MHD flow over a stretching porous sheet. The model which constituted highly nonlinear governing equations is transformed using similarity solution and then solved ...

Criterion for the thermal radiation spectrum in classical physics

open access: yesJournal of Physics Communications
Two criteria for the spectra of relativistic waves are proposed. Zero-point radiation provides the identity representation of the conformal group in Minkowski spacetime.

The significance of quadratic thermal radiative scrutinization of a nanofluid flow across a microchannel with thermophoretic particle deposition effects

open access: yesNanotechnology Reviews
The investigation of thermal radiation and thermophoretic impacts on nano-based liquid circulation in a microchannel has a significant impact on the cooling of microscale equipment, microliquid devices, and many more.

Adaptive fabric with emissivity regulation for thermal management of humans

open access: yesNanophotonics
The heat generation of the human body dramatically varies between resting and active status, so dynamic heat dissipation is required to ensure optimal thermal comfort.

Electron-mirror duality and thermality

open access: yesEuropean Physical Journal C: Particles and Fields
Classical electromagnetic radiation from moving point charges is foundational, but the thermal dynamics responsible for classical acceleration temperature are poorly understood. We investigate the thermal properties of classical electromagnetic radiation

Hawking radiation via tachyon condensation and its implications to tachyon cosmology

open access: yes, 2015
Hawking radiation can be derived from the collapsing process of matter to form a black hole. In this work, we show in more detail that the freely infalling process of a probe (D-)particle (or point-like object) in a non-extreme black hole background is ...
