Holography and a variable cosmological constant
Holography and a variable cosmological constant
An effective local quantum field theory with UV and IR cutoffs correlated in accordance with holographic entropy bounds is capable of rendering the cosmological constant (CC) stable against quantum corrections. By setting an IR cutoff to length scales relevant to cosmology, one easily obtains the currently observed ${\ensuremath{\rho}}_{\ensuremath{\Lambda}}\ensuremath{\simeq}{10}^{\ensuremath{-}47}\text{ }\text{ }{\mathrm{G}\mathrm{e}\mathrm{V}}^{4}$ …
