The Lambert equation of state in light of DESI BAO

Vipin Chandra Dubey, Subhajit Saha, Abdulla Al Mamon

The paper proposes a unified dark‑fluid model whose equation of state is expressed using the Lambert W function, and constrains its parameters with DESI BAO, supernova, and Hubble…

Unifying the Dark Sector with the New Generalized Chaplygin Gas: Observational Constraints

Abdulla Al Mamon, Andronikos Paliathanasis, Subhajit Saha

In light of recent cosmological observations, we examine a generalized Chaplygin gas model with a redshift-dependent exponent as a framework for describing the dark energy and dark…

Comparative Study of Gravity Models with Observational Constraints from \textit{OHD} and \textit{Pantheon+ datasets}

Anirudh Pradhan, S. A. Salve, V. B. Raut +1

The late-time acceleration of the universe remains one of the most significant open problems in modern cosmology. Modified gravity frameworks such as gravity provide a geome…

Viaggiu holographic dark energy in light of DESI DR2

Amlan K. Halder, Andronikos Paliathanasis, Stefano Viaggiu +2

We test the cosmological viability of the Viaggiu holographic dark energy (VHDE) model by using late-time observational data. In particular, we place constraints on the free parame…

Interplay of Anisotropy, Dzyaloshinskii Moriya Interaction and Symmetry breaking Fields in a 2D XY Ferromagnet

Rajdip Banerjee, Satyaki Kar

A two dimensional classical ferromagnetic XY model with its bound vortex-antivortex dominated quasi long range ordered phase at low temperatures is a long standing as well as well…

The peculiar case of the Viaggiu holographic dark energy

Somnath Saha, Subhajit Saha, Nilanjana Mahata

We study the plausibility of a holographic dark energy (HDE) model using the form of horizon entropy proposed by Viaggiu in 2014. This form of entropy is a generalization of the us…
