    "abstract": "The paper is an extension of quant-ph/9912102. The new framework is tested on\nthe 2-photon spontaneous emission and blackbody radiation. The new effects are\nrather subtle. The probability of the 2-photon emission is shown to consist of\na product of several terms: One which is identical to this from standard\nquantum optics and the remaining ones formally resembling detector\ninefficiencies (here arising from nontrivial vacuum structure). The blackbody\ndistribution is indistinguishable from the Planck law for T\u003cT_{critical} but\nfor T\u003eT_{critical} the maximum of the distribution gets lowered and shifts\ntowards higher frequencies. T_{critical} is a parameter that, in principle,\nshould be observable. No normal ordering of operators is needed and vacuum\nenergy is nonzero but finite. Vacuum is represented by a subspace spanned by\nground states of the oscillators and is not equivalent to the cyclic vector of\nthe GNS construction. The non-CCR algebra is discussed in more detail.",
