Bimodal mass primordial black holes in three-field inflation
M. M. Nasrolahzadeh, N. Khosravi
In this paper, we study the evolution of curvature and entropy perturbations in three-field inflation with non-canonical kinetic terms. Using the kinematic basis in field space, we…
Alleviating Cosmological Tensions with the Hadrosymmetric Twin Higgs
Mohammad Soroori Sotudeh, Zahra Davari, Sara Khatibi +1
The Hadrosymmetric Twin Higgs (HTH) model provides a natural solution to the little hierarchy problem by incorporating all three generations of quarks in a twin sector. Unlike othe…
Clusternets: A deep learning approach to probe clustering dark energy
Amirmohammad Chegeni, Farbod Hassani, Alireza Vafaei Sadr +2
Machine Learning (ML) algorithms are becoming popular in cosmology for extracting valuable information from cosmological data. In this paper, we evaluate the performance of a Convo…
Reconstruction of A Scale-Dependent Gravitational Phase Transition
Marzieh Farhang, Nima Khosravi
In this work we extend our earlier phenomenological model for a gravitational phase transition (GPT) and its generalization to early times by letting the modifications in the linea…
Can decaying dark matter scenarios alleviate both and tensions?
Zahra Davari, Nima Khosravi
Current tensions in cosmology, including and , provide one of the strong reasons to suspect the existence of physics beyond the standard model of cosmology (CDM). In…
Fluctuations in the Ginzburg-Landau Theory of Dark Energy: internal (in-)consistencies in PLANCK data set
Abdolali Banihashemi, Nima Khosravi
In this work, predictions of the Ginzburg-Landau theory of dark energy (GLT) for CMB lensing are studied. We find that the time and scale dependence of the dark energy fluctuations…
