Rényi entropy and subsystem distances in finite size and thermal states in critical XY chains
(IOP Publishing, 2020-08)
We study the R´enyi entropy and subsystem distances on one interval for the finite size and thermal states in the critical XY chains, focusing on the critical Ising chain and XX chain with zero transverse field. We construct ...
Universality classes for the Fisher metric derived from relative group entropy
(Elsevier Science, 2020-06)
We consider the Fisher metric which results from the Hessian of the relative group entropy, that we call group Fisher metric. In particular, the metrics corresponding to the Boltzmann–Gibbs, Tsallis, Kaniadakis and Abe ...
kappa-Entropy Based Restricted Boltzmann Machines
(Ieee, 2019-01-01)
Restricted Boltzmann Machines achieved notorious popularity in the scientific community in the last decade due to outstanding results in a wide range of applications and also for providing the required mechanisms to build ...

Entropy in locally-de Sitter spacetimes
(World Scientific Publ Co Pte Ltd, 2015-12-01)
As quotient spaces, Minkowski and de Sitter are fundamental spacetimes in the sense that they are known a priori, independently of Einstein equation. They represent different nongravitational backgrounds for the construction ...
General entropy-like uncertainty relations in finite dimensions
(IOP Publishing, 2014-11)
We revisit entropic formulations of the uncertainty principle (UP) for an arbitrary pair of positive operator-valued measures (POVM) A and B, acting on finite dimensional Hilbert space. Salicrú generalized (h, ) ϕ -entropies, ...
