“…Moreover, we have found that, for the same value of the classical black hole mass, the event horizon radius (and the BekensteinHawking entropy) decreases when the strength of the scale dependence increases. This is in agreement with the findings in [47][48][49][50][51][52][53][54][55][56][57][58][59][60][61].…”

In the present work we study the scale dependence at the level of the effective action of charged black holes in Einstein-Maxwell as well as in Einstein-powerMaxwell theories in (2 + 1)-dimensional spacetimes without a cosmological constant. We allow for scale dependence of the gravitational and electromagnetic couplings, and we solve the corresponding generalized field equations imposing the null energy condition. Certain properties, such as horizon structure and thermodynamics, are discussed in detail.

“…inflation [28][29][30][31], reheating [32], the cosmological microwave background [33,34], black hole formation [35][36][37] and the vacuum energy density during the evolution of the Universe [38]. As these phenomena are not entirely independent and are deserving of a detailed investigation in their own right, a full study of the early history of the Universe in presence of Higgsplosion is beyond the scope of this work.…”

Higgsplosion is a dynamical mechanism that introduces an exponential suppression of quantum fluctuations beyond the Higgsplosion energy scale E Ã and further guarantees perturbative unitarity in multiHiggs production processes. By calculating the Higgsplosion scale for spin 0, 1=2, 1 and 2 particles at leading order, we argue that Higgsplosion regulates all n-point functions, thereby embedding the standard model of particle physics and its extensions into an asymptotically safe theory. There are no Landau poles and the Higgs self-coupling stays positive. Asymptotic safety is of particular interest for theories of particle physics that include quantum gravity. We argue that in a Hippsloding theory one cannot probe shorter and shorter length scales by increasing the energy of the collision beyond the Higgsplosion energy and there is a minimal length set by r Ã ∼ 1=E Ã that can be probed. We further show that Higgsplosion is consistent and not in conflict with models of inflation and the existence of axions. There is also a possibility of testing Higgsplosion experimentally at future high energy experiments.

“…On this basis, we expect that it is feasible to compute the fingerprints of Asymptotic Safety in the Unruh effect. This may also be relevant for understanding the fate of black holes within Asymptotic Safety [88][89][90][91][92][93][94][95][96][97][98][99] based on first principles.…”

Quantum gravity signatures in the Unruh effect

We study quantum gravity signatures emerging from phenomenologically motivated multiscale models, spectral actions, and Causal Set Theory within the detector approach to the Unruh effect. We show that while the Unruh temperature is unaffected, Lorentz-invariant corrections to the two-point function leave a characteristic fingerprint in the induced emission rate of the accelerated detector. Generically, quantum gravity models exhibiting dynamical dimensional reduction exhibit a suppression of the Unruh rate at high energy while the rate is enhanced in Kaluza-Klein theories with compact extra dimensions. We quantify this behavior by introducing the "Unruh dimension" as the effective spacetime dimension seen by the Unruh effect and show that it is related, though not identical, to the spectral dimension used to characterize spacetime in quantum gravity. We comment on the physical origins of these effects and their relevance for black hole evaporation.
