Localization of quantum states within subspaces from the Lebesgue decomposition
L. L. Salcedo
Relying on the Lebesgue-type decomposition of positive operators, this work introduces a rigorous notion of localization probability of a quantum state within a given subspace of i…

Linearized renormalization
L. L. Salcedo
Using an infinitesimal approach, this work addresses the renormalization problem to deal with the ultraviolet divergences arising in quantum field theory. Under the assumption that…
