Consistency Condition for Slow-roll and Rapid-turn Inflation
Lilia Anguelova, Calin Iuliu Lazaroiu
We summarize our work on a consistency condition for inflation in two-field cosmological models, in the regime of rapid turn and third-order slow roll. To ensure a sustained inflat…
Infrared behavior in tame hyperbolizable two-field models
Elena Mirela Babalic, Calin Iuliu Lazaroiu
We discuss the behavior of cosmological curves and their first order infrared approximants near critical ends of the scalar manifold and near interior critical points of the sc…
Experimental test of Non-Commutative Quantum Gravity by VIP-2 Lead
Kristian Piscicchia, Andrea Addazi, Antonino Marciano +18
Pauli Exclusion Principle (PEP) violations induced by space-time non-commutativity, a class of universality for several models of Quantum Gravity, are investigated by the VIP-2 Lea…
On the slow roll expansion of one-field cosmological models
Calin Iuliu Lazaroiu
We study the infrared scale expansion of single field cosmological models using the Hamilton-Jacobi formalism, showing that its specialization at unit scale parameter recovers the…
Dynamical consistency conditions for rapid turn inflation
Lilia Anguelova, Calin Iuliu Lazaroiu
We derive consistency conditions for sustained slow roll and rapid turn inflation in two-field cosmological models with oriented scalar field space, which imply that inflationary m…
Double scaling limit of multi-matrix models at large
Valentin Bonzom, Victor Nador, Adrian Tanasa
In this paper, we study a double scaling limit of two multi-matrix models: the -invariant model with all quartic interactions and the bipartite $U(N) \times O(D…
Grothendieck's point of view and complexity in the black hole paradox
Andrei T. Patrascu
These are some speculations on how Grothendieck's point of view and the idea of complexity dynamics can come together in the problem of explaining the black hole information parado…
Strongest atomic physics bounds on Non-Commutative Quantum Gravity Models
Kristian Piscicchia, Andrea Addazi, Antonino Marciano +18
Investigations of possible violations of the Pauli Exclusion Principle represent critical tests of the microscopic space-time structure and properties. Space-time non-commutativity…
Dynamical renormalization and universality in classical multifield cosmological models
C. I. Lazaroiu
We study the scaling behavior of classical multifield cosmological models with complete scalar manifold and positive smooth scalar potential , introducing…
Non-metric geometry as the origin of mass in gauge theories of scale invariance
D. M. Ghilencea
We discuss gauge theories of scale invariance beyond the Standard Model (SM) and Einstein gravity. A consequence of gauging this symmetry is that their underlying 4D geometry is no…
A New Formula for the Gauge Charge
D. R. Grigore
We present a new formula for the gauge charge in the causal formalism for the QCD case.
Double scaling limit for the -invariant tensor model
Valentin Bonzom, Victor Nador, Adrian Tanasa
We study the double scaling limit of the -invariant tensor model, initially introduced in Carrozza and Tanasa, Lett. Math. Phys. (2016). This model has an interacting part…
Anti-BRST in the Causal Approach
D. R. Grigore
It is known that the elimination of the anomalies in all orders of perturbation theory is an open problem. The constrains given by usual invariance properties and the Wess-Zumino i…
String Defects, Supersymmetry and the Swampland
Carlo Angelantonj, Quentin Bonnefoy, Cezar Condeescu +1
Recently, Kim, Shiu and Vafa proposed general consistency conditions for six dimensional supergravity theories with minimal supersymmetry coming from couplings to strings. We test…
Factorization Formulas for Tree Amplitudes
D. R. Grigore
We present a coordinate space version of the factorization formula for the connected tree part of the chronological products. We consider a general framework and then we apply it f…
Chiral asymmetry in the weak interaction via Clifford Algebras
Ovidiu Cristinel Stoica
Despite its tremendous success, the Standard Model of particle physics does not explain why the weak interaction breaks chiral symmetry. Various unified theories got us closer to a…
On the large expansion of Hermitian multi-matrix models
Sylvain Carrozza, Frank Ferrari, Adrian Tanasa +1
We investigate the existence and properties of a double asymptotic expansion in and in invariant Hermitian multi-matrix mo…
Third Order Anomalies in the Causal Approach
Dan Radu Grigore
We consider gauge models in the causal approach and study the third order of the perturbation theory. We are interested in the computation of the anomalies in this order of the per…
Non-compact manifolds with Killing spinors
C. Rugina, A. Ludu
We present a result for non-compact manifolds with invertible Dirac operator, where we link the presence of a massless Killing spinor, with a harmonic, closed conformal Killing-Yan…
On the Super-Renormalizablity of Quantum Gravity in the Linear Approximation
Dan-Radu Grigore
We compute the one-loop contributions of the chronological products for massless gravity in the second order of the perturbation theory. We prove that the loop contributions are co…
Hidden symmetries of two-field cosmological models
Lilia Anguelova, Elena Mirela Babalic, Calin Iuliu Lazaroiu
We determine the most general time-independent Noether symmetries of two-field cosmological models with rotationally-invariant scalar manifold metrics. In particular, we show that…
Two-field constant roll inflation
Andrei Micu
Starting from the idea of realising constant roll inflation in string theory we develop the constant roll formalism for two scalar fields. We derive the two-field potential which i…
Diagrammatics of the quartic -invariant Sachdev-Ye-Kitaev-like tensor model
V. Bonzom, V. Nador, A. Tanasa
Various tensor models have been recently shown to have the same properties as the celebrated Sachdev-Ye-Kitaev (SYK) model. In this paper we study in detail the diagrammatics of tw…
Non-Gaussian disorder average in the Sachdev-Ye-Kitaev model
T. Krajewski, M. Laudonio, R. Pascalie +1
We study the effect of non-Gaussian average over the random couplings in a complex version of the celebrated Sachdev-Ye-Kitaev (SYK) model. Using a Polchinski-like equation and ran…
