Emergence of quadratic gravity from entanglement equilibrium
In this work, we derive the linearized equations of quadratic gravity from entropy prescription (which depends on the gravitational Lagrangian), we employ entanglement entropy. In this way, we are able to show the emergence...

On generalized entropies, Bayesian decisions and statistical diversity
Generalized entropies are introduced as maximal generalized informations achieved by a direct observation of data sources. Prominent examples are the Shannon and quadratic entropies. Their mutual anisotony and relations to ...

On relations between informations, entropies and Bayesian decisions
A class of power entropies is introduced which are concave functions of distributions for positive powers and convex for negative powers. It is shown that the maximal generalized informations are often convex power entropies. The

On the Relation between Generalized Entropy and the Bayes Decision Error
, the quadratic entropy has the tightest relation to the Bayes error among f-entropies.We deal with the relation between generalized entropies (f-entropies and the lower bound for the Bayes error under giv...

Monogamy of correlations and entropy inequalities in the Bloch picture
, we find dimension dependent entropy inequalities for the Tsallis 2-entropy. In particular, we present an analogue of the strong subadditivity and a quadratic entropyWe investigate monogamy of correlations and

Quantum treatment of atom-field interaction via the quadratic invariant
We introduce a new quantum treatment for the problem of the interaction between a two-level atom and field, which is expressed by the Jaynes-Cummings model. The treatment is built up on the construction of a quadratic invariant for the free-...

Landscape diversity of the Czech Republic ? possibilities of its determination
This paper shows several options of landscape diversity determination. Three different measures of diversity ? number of elements, Shannon-Wiener index and Rao?s diversity coefficient also called quadratic entropy ? were applied on ...

Decreasing entropy of dynamical black holes in critical gravity
Critical gravity is a quadratic curvature gravity in four dimensions which is ghost-free around the AdS background. Constructing a Vaidya-type exact solution, we show that the area of a black hole defined by a future outer trapping horizon c...
