Controllability of the Schrödinger equation on unbounded domains without geometric control condition

Matthias Täufer

We prove controllability of the Schrödinger equation in $R^{d}$ in any time $T > 0$ with internal control supported on nonempty, periodic, open sets. This demonstrates in pa…

Scale-free unique continuation principle, eigenvalue lifting and Wegner estimates for random Schrödinger operators

Ivica Nakić, Matthias Täufer, Martin Tautenhahn +1

We prove a scale-free, quantitative unique continuation principle for functions in the range of the spectral projector $χ_{(- \infty, E]} (H_{L})$ of a Schrödinger operator $H_{L}$ on a c…
