In 1996 L. Erdös showed that among planar domains of fixed area, the smallest principal eigenvalue of the Dirichlet Laplacian with a constant magnetic field is uniquely achieved on the disk. I will present a joint work with R. Ghanta and L. Junge, in which we establish a quantitative version of this inequality: we add an explicit remainder term depending on the field strength that measures how much the domain deviates from the disk.
