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…

Spin-spin effects from non-relativistic limit of Dirac-Pauli-Maxwell Lagrangian

Radmehr Fathi, Nima Khosravi

It is natural to expect that the electromagnetic spin-spin interaction has roots in a more fundamental theory: quantum electrodynamics in this case. To show this, we take the non-r…

Spin-Graviton-Spin: a unique probe of quantum gravity

Radmehr Fathi, Nima Khosravi

The existence of quantum gravity is the most important question in theoretical physics. Besides the theoretical development in this direction, looking for its low-energy consequenc…

Gluing different gravitational models: case

Amin Aalipour, Nima Khosravi

This paper presents a comprehensive analysis of junction conditions for gluing different gravitational theories across a non-null hypersurface. Using the variational approac…

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…
