Non-additive entropies in ... gravity ?
Nikos Kalogeropoulos
We present aspects of entropic functionals relatively recently introduced in Physics which are non-additive, in the conventional sense of the word, some of which have a power-law f…
Moduli of curve families and (quasi-)conformality of power-law entropies
Nikos Kalogeropoulos
We present aspects of the moduli of curve families on a metric measure space which may prove useful in calculating, or in providing bounds to, non-additive entropies having a power…
Entropies from coarse-graining: convex polytopes vs. ellipsoids
Nikos Kalogeropoulos
We examine the Boltzmann/Gibbs/Shannon and the non-additive Havrda-Charvát / Daróczy/Cressie-Read/Tsallis \ \ and the Kaniadakis -entropy \ $…
Ricci curvature, isoperimetry and a non-additive entropy
Nikos Kalogeropoulos
Searching for the dynamical foundations of the Havrda-Charvát/Daróczy/Cressie-Read/Tsallis non-additive entropy, we come across a covariant quantity called, alternatively, a genera…
Groups, non-additive entropy and phase transitions
Nikos Kalogeropoulos
We investigate the possibility of discrete groups furnishing a kinematic framework for systems whose thermodynamic behaviour may be given by non-additive entropies. Relying on the…
Extensive limit of a non-extensive entanglement entropy
Nikos Kalogeropoulos
An important calculation has been that of the (von Neumann) entanglement entropy of the ground state of 1-dimensional lattice models at criticality and of their massive perturbatio…
