In this paper, we consider the quantum correlations, coherence and entanglement, in neutrino oscillation. We find that the l 1-norm as a coherence measure is equal to the sum of the three possible concurrences for measuring the entanglement among different flavor modes which were calculated in the paper by Blasone M. et al., EPL, 112 (2015) 20007. Our result shows that the origin of the flavor entanglement in neutrino oscillation is the same as that of quantum coherence. Furthermore, in the wave packet framework, the variation of the l 1-norm is investigated by varying the wave packet width . As expected, the amount of coherence increases by due to the increase in overlapping of the mass eigenstates.

In this paper, we work on the topological Lifshitzlike black hole solutions of a special class of vacuum F(R)−gravity that are static and spherically symmetric. We investigate geometric and thermodynamic properties of the solutions with due respect to the validity of the first law of thermodynamics. We examine the van der Waals like behavior for asymptotically AdS solutions with spherical horizon by studying the P − v, G − T and C Q,P − r + diagrams and find a consistent result. We also investigate the same behavior for hyperbolic horizon and interestingly find that the system under study can experience a phase transition with negative temperature.
