Time minimal trajectories for a spin 1∕ 2 particle in a magnetic field

U Boscain, P Mason - Journal of Mathematical Physics, 2006 - pubs.aip.org
In this paper we consider the minimum time population transfer problem for the z component

Local controllability of 1D linear and nonlinear Schrödinger equations with bilinear control

K Beauchard, C Laurent - Journal de mathématiques pures et appliquées, 2010 - Elsevier
We consider a linear Schrödinger equation, on a bounded interval, with bilinear control, that
represents a quantum particle in an electric field (the control). We prove the exact …

Controllability of the discrete-spectrum Schrödinger equation driven by an external field

T Chambrion, P Mason, M Sigalotti… - Annales de l'Institut Henri …, 2009 - ems.press
We prove approximate controllability of the bilinear Schrödinger equation in the case in
which the uncontrolled Hamiltonian has discrete non-resonant spectrum. The results that are …
