Stability estimate in an inverse problem for non-autonomous Schrödinger equations

International audienceWe consider the inverse problem of determining the time dependent magnetic field of the Schrödinger equation in a bounded open subset of $R^n$, with $n \geq 1$, from a finite number of Neumann data, when the boundary measurement is taken on an appropriate open subset of the boundary. We prove the Lispchitz stability of the magnetic potential in the Coulomb gauge class by $n$ times changing initial value suitably
