Environment-assisted squeezing in a coherently driven non-Hermitian degenerate parametric oscillator
Muhdin Abdo Wodedo, Berihu Teklu, Konstantin G. Zloshchastiev +2
Environment-assisted approaches to nonclassical light offer a practical path to strong squeezing in imperfect, lossy platforms. In this paper, we study a degenerate parametric osci…
A New Window on Dynamical Dark Energy: Combining DESI-DR2 BAO with future Gravitational Wave Observations
Felipe Bruno Medeiros dos Santos, Jonathan Morais, Supriya Pan +2
Baryon acoustic oscillation (BAO) data from the Dark Energy Spectroscopic Instrument (DESI) appear to indicate the first evidence for dynamical dark energy (DDE), with a present-da…
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…
Accelerating scaling solutions from dark matter particle creation
Sudip Halder, Jaume de Haro, Supriya Pan +3
This article opens new window to obtain accelerating scaling attractors without any need of dark energy. We study cosmological dynamics in a two-fluid system where pressureless dar…
Is Dark Energy an Effective Manifestation of Non-equilibrium Thermodynamics? -- Insights from DESI
Sauvik Bhattacharjee, Sudip Halder, Jaume de Haro +2
We investigate the background cosmological expansion on the onset of cosmological homogeneous matter creation scenario, a dynamical dark matter approach (), and…
Triple exceptional point with unitary paths of unfolding in a three-site fermionic Swanson-like model
Bijan Bagchi, Aritra Ghosh, Miloslav Znojil
A fermionic three-site generalization of the popular bosonic Swanson model is studied as providing an exactly solvable five-parametric example of the quantum-mechanical unitary-evo…
