Query: Controllable quantum scars in semiconductor quantum dots   Quantum scars are enhancements of quantum probability density along classical
periodic orbits. We study the recently discovered phenomenon of strong,
perturbation-induced quantum scarring in the two-dimensional harmonic
oscillator exposed to a homogeneous magnetic field. We demonstrate that both
the geometry and the orientation of the scars are fully controllable with a
magnetic field and a focused perturbative potential, respectively. These
properties may open a path into an experimental scheme to manipulate electric
currents in nanostructures fabricated in a two-dimensional electron gas.
