Inverse phase transitions via dark sector chemical equilibration
Esau Cervantes, Felix Kahlhoefer, Jonas Matuszak +1
We study the cosmological evolution of the effective potential in a dark sector with a spontaneously broken Abelian gauge symmetry, populated out of equilibrium through the freeze-…
Light Dark Matter from Self-cooling Dark Sectors
Esau Cervantes, Andrzej Hryczuk, Stefan Lederer
Light thermally produced dark matter is subject to strong bounds stemming from its free-streaming impact on suppressing structure formation. In this paper we show that these limits…
Dynamics of Self-Interacting Dark Sectors
Esau Cervantes
This thesis investigates the dynamics of self-interacting dark sectors in the early Universe populated through the freeze-in mechanism. The main focus is on scenarios with self-num…
KineticXGPU: A Tensorized Collision Operator for Dark-Sector Self-Scattering
Esau Cervantes
We present KineticXGPU, a PyTorch-based implementation of the \(2\to2\) elastic self-collision operator for dark-sector momentum distributions. The discretized collision operator c…
Freezing-in Cannibals with Low-reheating Temperature
Nicolás Bernal, Esau Cervantes, Kuldeep Deka +1
The freeze-in mechanism provides a compelling framework for dark matter (DM) production, particularly suited to scenarios involving feeble interactions with the Standard Model (SM)…
Freezing-in Cannibal Dark Sectors
Esau Cervantes, Andrzej Hryczuk
Self-Interacting Dark Matter models can successfully explain dark matter (DM) production through interactions confined within the dark sector. However, they often lack measurable e…
Higgs-portal dark matter from non-supersymmetric strings
Esau Cervantes, Omar Perez-Figueroa, Ricardo Perez-Martinez +1
Large classes of non-supersymmetric string models equipped with standard-model features have been constructed, but very little of their phenomenology is known. Interestingly, their…
