Analogy between first-order phase transitions and blackbody radiation

The analogy between blackbody radiation and a phase equilibrium between vapor and liquid is drawn by deriving the Clapeyron equation in which the two probability distributions of blackbody radiation play the role of the two phases. The pressure of one of these distributions, which becomes negative at sufficiently high photon energies, is analogous to a negative pressure tending to break up a liquid. A similar type of critical phenomenon should be observed for blackbody radiation.     

The geodesic equation in five-dimensional relativity theory of Kaluza-Klein

In five-dimensional relativity theory of Kaluza-Klein the projection of the 5-geodesic equation is discussed in detail. The scalar occurring within this framework is first assumed to be variable. A simple classification of 5-geodesics is found and pictured with the help of a deformed 5-cone. On the assumption that the scalar is constant the 5-geodesic equation yields the Lorentz equation of motion for a charged particle. Intrinsic mass and intrinsic charge are introduced as new particle parameters. Mass and charge formulas are proposed.     

Amplitude-squared squeezing of the photon field in a Kerr-nonlinear blackbody

We find the photon field in a Kerr-nonlinear blackbody is an amplitude-squared squeezed state. The squeezing effect decreases with increasing temperature T. The amount of the amplitude-squared squeezing in a Kerr-nonlinear blackbody is much larger than the corresponding squeezing in normal blackbody, and the degree of amplitude-squared squeezing is much larger than the amplitude squeezing for the same range of parameters in a Kerr-nonlinear blackbody. The frequency ω_k and parameter γ also have important influences on the amplitude-squared squeezing in a Kerr-nonlinear blackbody.
