1. From Quantum Unstable Systems to the Decaying Dark Energy: Cosmological Implications / Szydłowski, Marek ; Stachowski, Aleksander ; Urbanowski, Krzysztof
We consider a cosmology with decaying metastable dark energy and assume that a decay process of this metastable dark energy is a quantum decay process. [...]

2. Singularities in particle-like description of FRW cosmology / Szydłowski, Marek ; Stachowski, Aleksander
In this paper, we apply the method of reducing the dynamics of FRW cosmological models with a barotropic form of the equation of state to the dynamical system of the Newtonian type to detect the finite scale factor singularities and the finite-time singularities. [...]

3. Simple cosmological model with inflation and late times acceleration / Szydłowski, Marek ; Stachowski, Aleksander
In the framework of polynomial Palatini cosmology, we investigate a simple cosmological homogeneous and isotropic model with matter in the Einstein frame. [...]

4. Quantum mechanical look at the radioactive-like decay of metastable dark energy / Szydłowski, Marek ; Stachowski, Aleksander ; Urbanowski, Krzysztof
We derive the Shafieloo, Hazra, Sahni and Starobinsky (SHSS) phenomenological formula for the radioactive-like decay of metastable dark energy directly from the principles of quantum mechanics. [...]
