Diffusion ionization of Rydberg atoms due to black-body radiation
free download

It was only recently established that the ubiquitous black-body radiation plays an important role in the spectroscopy of Rydberg atoms even at room temperature. U2 Black-body radiation causes shifts in the energy of atomic levels, 2 induces transitions between 

Intrinsic micro-quantity of chaos (thermal black body radiation, photocurrents)

Physical situations am considered in the frame of which this statement has been substantiated. MQC-conception has been demonstrated for fluctuations in the ideal gas. The expiassions of MQC are proposed for fluctuations of black body radiation, electrical and 

On the Formula for Black Body Radiation

Where A is a quantity de?ning the amplitude of the disturbance, and wt is the number of such disturbances per second. In order to obtain Wien's displacement law no must vary as 6, and then further we get Stefan's law if mA2 varies as 67, and the formula reduces to the 

A Suggestion as to the Origin of Black Body Radiation

This formula represents the observations for short and long Waves at various temperatures with considerable closeness; and, if it is the correct expression, it is held by some to prove that the classical equations of dynamics and electrodynamics are at fault. As I do not think 

A VARIATIONAL EXPECTATION-MAXIMIZATION METHOD FOR THE INVERSE BLACK BODY RADIATION PROBLEM
free download

ABSTRACT The inverse black body radiation problem, which is to reconstruct the area temperature distribution from the measurement of power spectrum distribution, is a well- known ill-posed problem. In this paper, a variational expectation-maximization (EM) 

Black-Body Radiation Once More

ABSTRACT The black-body radiation is an open problem, and in our opinion it will always be, because its foundations lack something essential. It is determined by two equilibrium conditions: one of its elements with those of the surrounding matter, the other of internal 

Jeans Instability of Rotating Viscous Molecular Cloud of Quantum Plasma under the Effect ofBlack-Body Radiation

ABSTRACT The problem of Jeans instability of rotating viscous molecular cloud of quantum plasmas has been investigated as considering the optically thick medium incorporating effect of porosity, permeability and black body radiation. The equations of the problem are

Developing Research and Experimentation Skills: Demonstrated using a Black Body Radiation Experiment.
free download

ABSTRACT Traditionally undergraduate labs are taught by having a student carry out a number of steps to set up equipment and take specific data to achieve a certain aim. With this approach there is little opportunity to develop many of the skills important in 

Jeans Instability of Optically Thick Quantum Plasma under the Influence of Black-Body Radiation
free download

ABSTRACT The Jeans instability of infinite homogeneous, self-gravitating quantum plasma is investigated under the assumption of optically thick medium and black body radiation. The general dispersion relation is obtained and the condition of instability is discussed. Index 

Some thermodynamic properties of black body radiation in an n-dimensional Euclidean space
free download

JP Oregon, JG Ayala, FA Brown ,tu-chemnitz.de ABSTRACT In this work we present the generalization of some thermodynamical properties of the black body radiation (BBR) towards a n-dimensional Euclidean space. The Planck function and the Stefan-Boltzmann law has already been given by Landsberg and De Vos 

Nonuniqueness of the Bose-Einstein statistical processes for the black body radiation
free download

An infinite number of stationary random processes with continuous energy distribution and upper energy limit of photons are possible as an explanation for black body radiation. Keywords: black body radiation, Bose–Einstein distribution, continuous energy distribution

THE GRAVITATIONAL INFLUENCE OF" QUASAR CLUSTERS ON THE COSMIC BLACK BODY RADIATION
free download

DW Sciama, MJ Rees ,gravityresearchfoundation.org Summary The cosmic black body radiation is observed to be highly isotropic, but if quasar clusters exist their gravitational effect should induce small (~ 0.1 per cent) anisotropics in the radiation. There is some preliminary evidence in favour of this idea and so it seems worth 

Black body radiation in quantum Statistical Mechanics distribution

AS Arife ,gsjournal.net All surfaces at a finite temperature emit electromagnetic radiation, but at room temperature this energy emission is weak and almost entirely distributed in the far infrared spectrum. With increasing temperature the total radiated power increases rapidly, proportional to the

ADVANCES IN BLACK BODY RADIATION

JL Haller Jr ,rxiv.org ABSTRACT The past century has seen many dividends from Planck's theory for black body radiation. Today we advance that theory to provide an explanation for the acceleration of the Universe and other cosmological observations. We do this by arguing:

Absence of Entanglement in Black Body Radiation
free download

ABSTRACT Using temperature Green's function approach we investigate classical correlation and entanglement of two particles in non-interacting thermal boson systems, especially in the black body radiation. The two-spin density matrix for fixed distance is given by the 

Minimal length, maximal momentum and thermodynamics of black body radiation

ABSTRACT In this paper we study thermodynamics of black body radiation in the presence of quantum gravitational effects through a Generalized Uncertainty Principle (GUP) that admits both a minimal measurable length and a maximal momentum. We focus on quantum
