Limits of Stochastic Semigroups and Block-Triangular Majorisation
Fabio Deelan Cunden, Jakub Czartowski, Giovanni Gramegna +1
We investigate limits of semigroups of stochastic matrices defined by their invariant distribution. Given probability vectors depending on a parameter , we introduce a no…
Maximal Minimal Spacing for Random Points
Fabio Deelan Cunden, Noemi Cuppone, Giovanni Gramegna +1
From random points on a line we wish to select points so as to maximize the minimal spacing between them. We consider an initial configuration with independent and iden…
Rotating-Wave and Secular Approximations for Open Quantum Systems
Daniel Burgarth, Paolo Facchi, Giovanni Gramegna +1
We derive a nonperturbative bound on the distance between evolutions of open quantum systems described by time-dependent generators. We show how this result can be employed to prov…
The Most Dispersed Subset of Random Points in
Fabio Deelan Cunden, Noemi Cuppone, Giovanni Gramegna +1
Consider a population of individuals, each having different traits, and an additive measure, called dispersion, which rewards large pairwise separations between trait…
