Non-Minimally Coupled Warm Inflation in the Defining Frame

Adrián Casado-Turrión, Paulo B. Ferraz, Mindaugas Karčiauskas +1

Warm inflation in scalar-tensor theories of gravity is investigated in the `defining' frame, where the theory and its parameter values are specified. Translating the result…

Primordial Black Holes as Dark Matter and the Tachyonic Trap During Inflation

Yuma S. Furuta, Mindaugas Karčiauskas, Kazunori Kohri +1

We show that resonant processes during multi-field inflation can generate a large curvature perturbation on small scales. This perturbation naturally leads to the formation of prim…

Constraining the General Oscillatory Inflaton Potential with Freeze-in Dark Matter and Gravitational Waves

Jose A. R. Cembranos, Mindaugas Karčiauskas

The reheating phase after inflation is one of the least observationally constrained epochs in the evolution of the Universe. The forthcoming gravitational wave observatories will e…

Quintessence in the Weyl-Gauss-Bonnet model

José Jaime Terente Díaz, Konstantinos Dimopoulos, Mindaugas Karčiauskas +1

Quintessence models have been widely examined in the context of scalar-Gauss-Bonnet gravity, a subclass of Horndeski's theory, and were proposed as viable candidates for Dark Energ…

Gauss-Bonnet Dark Energy and the Speed of Gravitational Waves

José Jaime Terente Díaz, Konstantinos Dimopoulos, Mindaugas Karčiauskas +1

Gauss-Bonnet Dark Energy has been a popular model to explain the accelerated expansion of the Universe. Quite generically it also predicts the speed of gravitational waves …

Comoving curvature perturbation in Jordan and Einstein frames

José Jaime Terente Díaz, Mindaugas Karčiauskas

In the context of models of gravity, the conformal invariance of the curvature perturbation on uniform-field slices has been already demonstrated in several publications. I…
