Title Black holes, conformal symmetry, and fundamental fields Type Journal Article
Year 2024 Publication Classical and Quantum Gravity Abbreviated Journal (up) Class. Quantum Gravity
Volume 41 Issue 8 Pages 085003 - 14pp
Keywords black holes; horizons; singularities; conformal symmetry; quantum fields; Standard Model
Abstract Cosmic censorship protects the outside world from black hole singularities and paves the way for assigning entropy to gravity at the event horizons. We point out a tension between cosmic censorship and the quantum backreacted geometry of Schwarzschild black holes, induced by vacuum polarization and driven by the conformal anomaly. A similar tension appears for the Weyl curvature hypothesis at the Big Bang singularity. We argue that the requirement of exact conformal symmetry resolves both conflicts and has major implications for constraining the set of fundamental constituents of the Standard Model.

Title Prime Numbers, Quantum Field Theory and the Goldbach Conjecture Type Journal Article
Year 2012 Publication International Journal of Modern Physics A Abbreviated Journal (up) Int. J. Mod. Phys. A
Volume 27 Issue 23 Pages 1250136 - 24pp
Keywords Quantum field theory; number theory; renormalization; Goldbach conjecture
Abstract Motivated by the Goldbach conjecture in number theory and the Abelian bosonization mechanism on a cylindrical two-dimensional space-time, we study the reconstruction of a real scalar field as a product of two real fermion (so-called prime) fields whose Fourier expansion exclusively contains prime modes. We undertake the canonical quantization of such prime fields and construct the corresponding Fock space by introducing creation operators b(p)(dagger) – labeled by prime numbers p – acting on the vacuum. The analysis of our model, based on the standard rules of quantum field theory and the assumption of the Riemann hypothesis, allows us to prove that the theory is not renormalizable. We also comment on the potential consequences of this result concerning the validity or breakdown of the Goldbach conjecture for large integer numbers.

Title Gravity and handedness of photons Type Journal Article
Year 2017 Publication International Journal of Modern Physics D Abbreviated Journal (up) Int. J. Mod. Phys. D
Volume 26 Issue 12 Pages 1742001 - 5pp
Keywords Quantum fields in curved spacetime; symmetry and conservation laws; electromagnetic wave propagation; anomalies
Abstract Vacuum fluctuations of quantum fields are altered in the presence of a strong gravitational background, with important physical consequences. We argue that a nontrivial spacetime geometry can act as an optically active medium for quantum electromagnetic radiation, in such a way that the state of polarization of radiation changes in time, even in the absence of electromagnetic sources. This is a quantum effect, and is a consequence of an anomaly related to the classical invariance under electric-magnetic duality rotations in Maxwell theory.

Title Enhanced local-type inflationary trispectrum from a non-vacuum initial state Type Journal Article
Year 2012 Publication Journal of Cosmology and Astroparticle Physics Abbreviated Journal (up) J. Cosmol. Astropart. Phys.
Volume 05 Issue 5 Pages 019 - 13pp
Keywords inflation; non-gaussianity; quantum field theory on curved space; cosmological perturbation theory
Abstract We compute the primordial trispectrum for curvature perturbations produced during cosmic inflation in models with standard kinetic terms, when the initial quantum state is not necessarily the vacuum state. The presence of initial perturbations enhances the trispectrum amplitude for configuration in which one of the momenta, say k(3), is much smaller than the others, k(3) << k(1,2,4). For those squeezed con figurations the trispectrum acquires the so-called local form, with a scale dependent amplitude that can get values of order epsilon(k(1)/k(3))(2). This amplitude could be larger than the prediction of the so-called Maldacena consistency relation by a factor as large as 10(6), and could reach the sensitivity of forthcoming observations, even for single-field inflationary models.

Title Acceleration radiation, transition probabilities and trans-Planckian physics Type Journal Article
Year 2010 Publication New Journal of Physics Abbreviated Journal (up) New J. Phys.
Volume 12 Issue Pages 095017 - 18pp
Keywords
Abstract An important question in the derivation of the acceleration radiation, which also arises in Hawking's derivation of black hole radiance, is the need to invoke trans-Planckian physics in describing the creation of quanta. We point out that this issue can be further clarified by reconsidering the analysis in terms of particle detectors, transition probabilities and local two-point functions. By writing down separate expressions for the spontaneous-and induced-transition probabilities of a uniformly accelerated detector, we show that the bulk of the effect comes from the natural (non-trans-Planckian) scale of the problem, which largely diminishes the importance of the trans-Planckian sector. This is so, at least, when trans-Planckian physics is defined in a Lorentz-invariant way. This analysis also suggests how one can define and estimate the role of trans-Planckian physics in the Hawking effect itself.
