A statistical representation of the cosmological constant from finite size effects at the apparent horizon
In this paper we present a statistical description of the cosmological constant in terms of massless bosons (gravitons). To this purpose, we use our recent results implying a non vanishing temperature $${T_{\Lambda }}$$ T Λ for the cosmological constant. In particular, we found that a non vanishing...

| 520 | |a In this paper we present a statistical description of the cosmological constant in terms of massless bosons (gravitons). To this purpose, we use our recent results implying a non vanishing temperature $${T_{\Lambda }}$$ T Λ for the cosmological constant. In particular, we found that a non vanishing $$T_{\Lambda }$$ T Λ allows us to depict the cosmological constant $$\Lambda $$ Λ as composed of elementary oscillations of massless bosons of energy $$\hbar \omega $$ ħ ω by means of the Bose–Einstein distribution. In this context, as happens for photons in a medium, the effective phase velocity $$v_g$$ v g of these massless excitations is not given by the speed of light c but it is suppressed by a factor depending on the number of quanta present in the universe at the apparent horizon. We found interesting formulas relating the cosmological constant, the number of quanta N and the mean value $$\overline{\lambda }$$ λ ¯ of the wavelength of the gravitons. In this context, we study the possibility to look to the gravitons system so obtained as being very near to be a Bose–Einstein condensate. Finally, an attempt is done to write down the Friedmann flat equations in terms of N and $$\overline{\lambda }$$ λ ¯ . | ||

A statistical representation of the cosmological constant from finite size effects at the apparent horizon |
| abstract |
In this paper we present a statistical description of the cosmological constant in terms of massless bosons (gravitons). To this purpose, we use our recent results implying a non vanishing temperature $${T_{\Lambda }}$$ T Λ for the cosmological constant. In particular, we found that a non vanishing $$T_{\Lambda }$$ T Λ allows us to depict the cosmological constant $$\Lambda $$ Λ as composed of elementary oscillations of massless bosons of energy $$\hbar \omega $$ ħ ω by means of the Bose–Einstein distribution. In this context, as happens for photons in a medium, the effective phase velocity $$v_g$$ v g of these massless excitations is not given by the speed of light c but it is suppressed by a factor depending on the number of quanta present in the universe at the apparent horizon. We found interesting formulas relating the cosmological constant, the number of quanta N and the mean value $$\overline{\lambda }$$ λ ¯ of the wavelength of the gravitons. In this context, we study the possibility to look to the gravitons system so obtained as being very near to be a Bose–Einstein condensate. Finally, an attempt is done to write down the Friedmann flat equations in terms of N and $$\overline{\lambda }$$ λ ¯ . |

We found interesting formulas relating the cosmological constant, the number of quanta N and the mean value $$\overline{\lambda }$$ λ ¯ of the wavelength of the gravitons. In this context, we study the possibility to look to the gravitons system so obtained as being very near to be a Bose–Einstein condensate. Finally, an attempt is done to write down the Friedmann flat equations in terms of N and $$\overline{\lambda }$$ λ ¯ .</subfield></datafield><datafield tag="540" ind1=" " ind2=" "><subfield code="a">Nutzungsrecht: © Springer Science+Business Media New York 2016</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bose–Einstein condensation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Physics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Classical and Quantum Gravitation, Relativity Theory</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Theoretical, Mathematical and Computational Physics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Astronomy, Astrophysics and Cosmology</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Gravitons</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cosmological constant</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Quantum Physics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Differential Geometry</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Apparent horizon</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cosmology and Nongalactic Astrophysics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">High Energy Physics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Astrophysics</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">General Relativity and Quantum Cosmology</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Theory</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">General relativity and gravitation</subfield><subfield code="d">Dordrecht [u.a.] : Springer, 1970</subfield><subfield code="g">48(2016), 7, Seite 1-12</subfield><subfield code="w">(DE-627)129605735</subfield><subfield code="w">(DE-600)242130-6</subfield><subfield code="w">(DE-576)015100022</subfield><subfield code="x">0001-7701</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:48</subfield><subfield code="g">year:2016</subfield><subfield code="g">number:7</subfield><subfield code="g">pages:1-12</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1007/s10714-016-2095-5</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://arxiv.org/abs/1606.08588</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHY</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-AST</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-AST</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2409</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">33.21</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">39.30</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">48</subfield><subfield code="j">2016</subfield><subfield code="e">7</subfield><subfield code="h">1-12</subfield></datafield></record></collection>
