Three invariants of strange attractors derived through hypergeometric entropy

Chaos, Solitons and Fractals, 2023
A new description of strange attractor systems through three geometrical and dynamical invariants is provided. They are the correlation dimension ($\mathcal{D}$) and the correlation entropy ($\mathcal{K}$), both having attracted attention over the past ...

Understanding gravitational entropy of black holes: A new proposal via curvature invariants

Physical Review D, 2022
Partly motivated by the arrow of time problem in cosmology and the Weyl curvature hypothesis formulated by Roger Penrose, previous works in the literature have proposed - among other possibilities - the square of the Weyl curvature, as being the ...

Estimation of dynamical invariants without embedding by recurrence plots

Chaos, 2004
In this paper we show that two dynamical invariants, the second order Renyi entropy and the correlation dimension, can be estimated from recurrence plots (RPs) with arbitrary embedding dimension and delay. This fact is interesting as these quantities are

On the Lindblad equation for open quantum systems: Rényi entropy rate and weak invariants [PDF]

Journal of Physics: Conference Series, 2018
© Published under licence by IOP Publishing Ltd. A brief review of two recent topics on the Lindblad equation is presented. One is concerned with time evolution of the quantum Ré nyi entropy under the equation.
