Massive gravity solution of black holes and entropy bounds
The dRGT massive gravity represents a comprehensive theory which properly describes massive graviton field. Latterly, the exact spherical solutions...

Entropy in General
Entropy, introduced in Chap. 8 , is generalized here for all fluids. The generalization operates on new...

Entropy, Quasiequilibrium, and Projectors Field
Projection operators Py contribute both to the invariance equation (3.2), and to the film extension of the dynamics (4.5). Limiting results, exact...

Analytical solution to optimise the entropy generation in EMHD flow of non-Newtonian fluid through a microchannel
This study investigates the thermal characteristics and irreversibility analysis of the combined electro-osmotic and electromagnetic flow of a couple...

Data driving design of high-entropy alloys for lightweight and dynamic applications
The topic of high-entropy alloys is one of the focus for both physics and materials research. High-entropy alloys were usually defined as solid...

Entanglement entropy in de Sitter: no pure states for conformal matter
In this paper, we consider the entanglement entropy of conformal matter for finite and semi-infinite entangling regions, as well as the formation of...

Revisit the entanglement entropy with gravitational anomaly
In this paper we study the entanglement entropy in the CFT 2 , whose gravity dual is AdS 3 spacetime with a Chern-Simons term. Using the generalized...
