A Phase Space Criterion for Dynamical Amrein-Berthier Uncertainty

Piero D'Ancona, Diego Fiorletta, Fabio Nicola

We prove a phase space criterion for dynamical Amrein-Berthier uncertainty principles. The abstract result says that, for a Fourier integral operator $A \in F I O (χ)$ associated with…

Dynamical Amrein-Berthier Uncertainty for Fractional Schrödinger Flows

Piero D'Ancona, Diego Fiorletta

We prove dynamical Amrein-Berthier uncertainty principles for fractional Schrödinger flows. For the free Hamiltonian $H = (- Δ)^{α}$ on $L^{2} (R^{n})$ , with $α > \frac{1}{2}$ , we sho…

A dynamical Amrein-Berthier uncertainty principle

Piero D'Ancona, Diego Fiorletta

Given a selfadjoint magnetic Schrödinger operator \begin{equation*} H = ( i \partial + A(x) )^2 + V(x) \end{equation*} on $L^{2} (R^{n})$ , with $V (x)$ strictly subquadratic a…
