A new fast numerical method for the generalized Rosen-Zener model
Christian Bonhomme, Stefano Pozza, Niel Van Buggenhout
In quantum mechanics, the Rosen-Zener model represents a two-level quantum system. Its generalization to multiple degenerate sets of states leads to larger non-autonomous linear sy…

A new Legendre polynomial-based approach for non-autonomous linear ODEs
Stefano Pozza, Niel Van Buggenhout
We introduce a new method with spectral accuracy to solve linear non-autonomous ordinary differential equations (ODEs) of the kind $ \frac{d}{dt}\tilde{u}(t) = \tilde{f}(t) \tilde{…

A new closed-form expression for the solution of ODEs in a ring of distributions and its connection with the matrix algebra
Stefano Pozza
A new expression for solving homogeneous linear ODEs based on a generalization of the Volterra composition was recently introduced. In this work, we extend such an expression, show…
