Case study 2.1 Quantum theory and black-body radiation. In 1899 Liimmer and Pringsheim investigated how the energy from a black-body radiator was distributed. The shape of the resulting spectral lines (Figure 2.9) was not easy to explain. According to the prevailing classical theory, which argued that radiation was emitted continuously, the energy radiated at each wavelength (EA) should vary with wavelength (X) (Figure 2.10).

Experimental foundations of quantum theory

Giampiero V. M. Esposito, Giuseppe Marmo, Gennaro Miele +1 more

The experimental foundations of quantum theory are presented in some detail in this chapter: on the one hand, the investigation of black-body radiation, which helps in developing an interdisciplinary view of physics, besides having historical interest; on the other hand, the energy and linear momentum of photons, atomic spectra, discrete energy levels, wave-like properties of electrons, interference phenomena and uncertainty relations. Black-body radiation Black-body radiation is not just a topic of historical interest. From a pedagogical point of view, it helps in developing an interdisciplinary view of physics, since it involves, among the other, branches of physics such as electrodynamics and thermodynamics, as well as a new constant of nature, the Planck constant, which is peculiar to quantum theory and quantum statistics. Moreover, looking at modern developments, the radiation that pervades the whole universe (Gamow 1946, Penzias and Wilson 1965, Smoot et al . 1992, Spergel et al . 2003) is a black-body radiation, and the expected emission of particles from black holes (space–time regions where gravity is so strong that no light ray can escape to infinity, and all nearby matter gets eaten up) is also (approximately) a black-body radiation (Hawking 1974, 1975). In this section, relying in part on Born (1969), we are aiming to derive the law of heat radiation, following Planck's method. We think of a box for which the walls are heated to a definite temperature T .

Absence of Entanglement in Black Body Radiation

Jae Weon Lee, Sangchul Oh, Jaewan Kim

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 generalized Werner state. Contrary to the fermion case the entanglement is absent in the spin density matrix. This result is applicable to reveal the nature of astronomical objects using an Aspect-type Bell inequality violation experiment.
