Abnormal properties of spontaneous emission in a Kerr nonlinear blackbody

Finite-size corrections to the radiation laws of a Kerr nonlinear blackbody

“…Some identical systems of the ensemble may be in an eigenstate of the Hamiltonian H′ em given by Eq. (7). The distribution of the ensemble over the eigenstates is described by the density operator of the squeezed thermal radiation state…”

“…Such a KNB can be regarded as a cavity having perfectly conducting walls and kept at a constant temperature T. In the previous works, Cheng pointed out that in a KNB bare photons with opposite wave vectors and helicities are bound into pairs and unpaired photons are transformed into a different kind of quasiparticle, the nonpolariton. Furthermore, Cheng et al [5][6][7][8] also studied the other important properties of a KNB, including the radiation properties, the condensation state of the photon system and so on. They found that a KNB has many special properties which are quite different from a normal blackbody and may have enormous values of theory and application.…”
