TY - JOUR T1 - An Investigation of the Modes of Radiation in a Symmetric Container in Equilibrium and the Possibility of Photon Condensation in an Extent Larger than Optical Microcavity TT - بررسی مدهای تابش در یک مخزن متقارن درحالت ترازمند و امکان چگالش فوتون‌ها در گستره بزرگتر از میکروکاواک اپتیکی JF - opsi JO - opsi VL - 21 IS - 0 UR - http://opsi.ir/article-1-679-en.html Y1 - 2015 SP - 1285 EP - 1288 KW - Vectorial Helmholtz Equation KW - Energy Current Density KW - Stationary and Equilibrium Modes KW - Photon Condensation KW - Optical Microcavity N2 - We introduce a photon container with suitable characteristics and boundary conditions for photon ordering and in the linear approximation solve the Helmholtz equation for vector potential in spherical coordinates. The polar and radial dependences of the obtained relations for the eigen modes advise a likelihood condensation. In addition the successive zeros of the radial component and polar component of the energy current density lead to photon confining in a configuration of photon bundles. For the photons in every bundle conditions comparable with their condition in an optical microcavity are provideable so that their dispersion relation becomes nonrelativesticly and the photons may attain number conserving thermal equilibrium.
