Abstract We investigate theoretical and observational aspects of a warm inflation scenario driven by the $$\beta $$ β -exponential potential, which generalizes the well-known power law inflation. In such a scenario, the decay of the inflaton field i

Abstract We establish new constraints on f(T) gravity models by using cosmological data. In particular, we investigate the restrictions given by the gas mass fraction measurements of galaxy clusters and transversal BAO data. Both data sets are regard

We identify patterns of ground state entanglement, or quantum discord, in qubit clusters with three and four qubits, that are induced by varying the couplings between next-nearest neighbors in the clusters. We show that these entanglement patterns ca

We investigate the possibility of the existence of different types of thermal entanglement in the two-spin Heisenberg $XY$ model, which are distinguished by the behavior of the concurrence as a function of the model parameters. Singularities in the t
