Haantjes Algebras and Diagonalization
Piergiulio Tempesta, Giorgio Tondo
We introduce the notion of Haantjes algebra: It consists of an assignment of a family of operator fields on a differentiable manifold, each of them with vanishing Haantjes torsion.…
Uniqueness and characterization theorems for generalized entropies
Alberto Enciso, Piergiulio Tempesta
The requirement that an entropy function be composable is key: it means that the entropy of a compound system can be calculated in terms of the entropy of its independent component…
A duality principle for the multi-block entanglement entropy of free fermion systems
Jose A. Carrasco, Federico Finkel, Artemio Gonzalez-Lopez +1
The analysis of the entanglement entropy of a subsystem of a one-dimensional quantum system is a powerful tool for unravelling its critical nature. For instance, the scaling behavi…
