The process is inherently independentof the coherence of the incoming photons, and, thanks to the large population ofmetastable triplet states given by the transfer, up-converted photons can be ob-tained by using ultra low excitation power densities similar to the solar emissionlevel.PACS 33.50.-j – Fluorescence and phosphorescence; radiationless transitions,quenching (intersystem crossing, internal conversion).PACS 42.79.Nv – Optical frequency converters.PACS 33.80.-b – Photon interactions with molecules.","PeriodicalId":54708,"journal":{"name":"Nuovo Cimento Della Societa Italiana Di Fisica B-Basic Topics in Physics","volume":"125 1","pages":"569-578"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66579722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We derive the modified Friedmann equations and show that they correspond to Cardassian-like equations. We also show that, under suitable assumptions on the equation of state of the matter term sourcing the gravitational field, it is indeed possible to get an accelerated expansion, in agreement with the Hubble diagram of both Type Ia Supernovae (SNeIa) and Gamma Ray Bursts (GRBs). Unfortunately, to achieve such a result one has to postulate a matter density parameter much larger than the typical $Omega_M simeq 0.3$ value inferred from cluster gas mass fraction data.","PeriodicalId":54708,"journal":{"name":"Nuovo Cimento Della Societa Italiana Di Fisica B-Basic Topics in Physics","volume":"125 1","pages":"1133-1142"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66579320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
