Simple diamagnetic monotonicities for Schroedinger operators with inhomogeneous magnetic fields of constant direction
Hajo Leschke, Rainer Ruder, Simone Warzel
Under certain simplifying conditions we detect monotonicity properties of the ground-state energy and the canonical-equilibrium density matrix of a spinless charged particle in the…
