Material matter effects in gravitational UV/IR mixing

Abstract: We propose a matter effect for the gravitational ultraviolet/infrared (UV/IR) mixing solution to the cosmological constant problem. Previously, the gravitational UV/IR mixing model implied a non-standard equation of state for dark energy, contradicting observation. In contrast, matter effect gravitational UV/IR mixing accommodates a standard ΛCDM cosmology with constant dark energy. Notably, there are new density-dependent predictions for futuristically precise measurements of fundamental parameters, like the … Show more

“…However, there are reasons to think that quantum field theory's character is altered before the black hole entropy bound is saturated. As identified by Cohen, Kaplan, and Nelson [16], effective field theories describing the dynamics of a region with size L and corresponding infrared cutoff Λ IR ∼ 1 L , may break down if the virtual energy density inside that region implies a black hole horizon larger than L. This theory also provides a possible resolution of the cosmological constant problem [16][17][18][19]. In effective field theory terms, this "gravitational UV/IR mixing" indicates a correspondence between UV and IR cutoffs, which applies going from the UV to the IR, and from the IR to the UV.…”

“…While not a completely conventional ingredient in the swampland toolkit, there is a growing sense that entropy considerations will play an important role in the program in the future (in fact the refined dS conjecture was based on entropic arguments [103]), and moreover they fit naturally under same umbrella in which UV physics affects IR physics in un-EFT-like ways (known broadly as "UV/IR mixing.") Recently there has been a burst of new activity related to the Cohen-Kaplan-Nelson (CKN) bound [136,[138][139][140][141][142][143].…”

“…Formulated in terms of UV and IR cutoffs, the CKN bound takes the form Λ IR > M p /Λ 2 U V . Resolving the appropriate interpretation of this UV/IR correlation is an ongoing effort of considerable importance for phenomenology; depending on the meaning, it can either imply that quantum gravity effects are detectable in precision experiments [138,140,141] or that they are as negligible as one might expect from an effective field theory supplemented by corrections in powers of G N [139,142].…”

“…We begin by computing the modification to the Coulomb potential and infer bounds on L eff (ǫ ⋆ = αm e ) from atomic physics. We then consider state depletion effects on L eff (ǫ ⋆ = m e ) from g − 2, since that precisely-known quantity has been of particular interest in the CKNrelated literature [1,[7][8][9][10]. Finally we briefly consider bounds at higher energies based on the measured resolution of detectors.…”

“…In Ref. [1] it was interpreted as an IR momentum cutoff on Feynman graphs for a given UV cutoff, and recently there has been renewed interest in this interpretation of the bound and its possible implications for precision measurements [7][8][9]. In fact this interpretation suggests that the effects of quantum gravity on precision observables are so large that they may be detectable following plausible experimental improvements [1,[7][8][9].…”
