Inverse Feshbach's problem: Solvability and solutions
Miloslav Znojil
Given a certain specific, by matrix form of the Feshbach's effective (i.e., energy-dependent) Hamiltonian , the inverse-problem reconstruction of the…
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…
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…
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…
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…
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…
