European Physical Journal C: Particles and FieldsIn this paper, we investigate the validity of the so-called cosmic no-hair conjecture in the framework of anisotropic inflation models of non-canonical scalar fields non-minimally coupled to a two-form field.

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.Plant pathogens worldwide continue to spread outside of their native ranges into new habitats. Our results highlight the importance of investigating variable processes like land use legacy that can correlate with impacts of non‐native plant pathogens.

Cosmic microwave background probes models of inflation
Physical Review Letters, 1992 Inflation creates both scalar (density) and tensor (gravity wave) metric perturbations. We find that the tensor mode contribution to the CMB anisotropy on large-angular scales can only exceed that of the scalar mode in models where the spectrum of perturbations deviates significantly from scale invariance (e.g., extended and power-law inflation models ...

Simple cosmological model with inflation and late times acceleration
European Physical Journal C: Particles and Fields, 2018 In the framework of polynomial Palatini cosmology, we investigate a simple cosmological homogeneous and isotropic model with matter in the Einstein frame.

Intermediate Inflation or Late Time Acceleration?
Advances in High Energy Physics, 2008 The expansion rate of “intermediate inflation” lies between the exponential and power law expansion but corresponding accelerated expansion does not start at the onset of cosmological evolution.

T-model Higgs inflation and metastable cosmic strings
Journal of High Energy PhysicsWe present the formation of metastable cosmic strings (CSs) in the context of a supersymmetric (SUSY) left-right model. The spontaneous SU(2)R symmetry breaking occurs during a stage of T-model (Higgs) inflation (TI) driven by an SU(2)R triplet ...

Why concave rather than convex inflaton potential?
European Physical Journal C: Particles and Fields, 2018 The Planck data on cosmic microwave background indicates that the Starobinsky-type model with concave inflation potential is favored over the convex-type chaotic inflation. Is there any reason for that?
