Pushing the Primordial Frontier: Cosmological Collider Signatures at Strong Mixing
Javier Huenupi, Claudio Muñoz, Gonzalo A. Palma +1
The paper presents an analytic method to study primordial non‑Gaussianity in multifield inflation that fully accounts for strong curvature‑isocurvature mixing, providing exact bisp…
Pushing the Primordial Frontier: Exact Linear Solutions in Multifield Inflation
Javier Huenupi, Claudio Muñoz, Gonzalo A. Palma +1
We present exact analytic solutions for the linear dynamics of a two-field inflationary system in which the primordial curvature perturbation is coupled to an isocurvature per…
Kink dynamics for the Yang-Mills field in an extremal Reissner-Nordström black hole
Ignacio Acevedo, Claudio Muñoz
Considered in this work is the Yang-Mills field in an extremal Reissner-Nordström black hole, a physically motivated mathematical model introduced by BizoÅ and Kahl. The kink is…
Decay of solutions of nonlinear Dirac equations: the 2D case
Sebastian Herr, Christopher Maulén, Claudio Muñoz
We study the long-time behavior of small solutions for a broad class of 2D Dirac-type equations with suitable nonlinearities. First, we prove that for nonlinearities with power $p\…
On the asymptotic dynamics for the -supercritical gKDV equation
Ricardo Freire, Claudio Muñoz
We study the -supercritical generalized Korteweg-de Vries equation (gKdV) with nonlinearities . While local well-posedness in is classical, the long-time dynamics i…
Decay of solutions of nonlinear Dirac equations
Sebastian Herr, Christopher Maulén, Claudio Muñoz
We study the long-time behavior of small and large solutions to a broad class of nonlinear Dirac-type equations. Our results are classified in 1D massless and massive cases, 3D gen…
