Query: Tunable transmission via quantum state evolution in oval quantum dots   We explore the quantum transmission through open oval shaped quantum dots.
The transmission spectra show periodic resonances and, depending on the
geometry parameter, a strong suppression of the transmission for low energies.
Applying a weak perpendicular magnetic field changes this situation drastically
and introduces a large conductance. We identify the underlying mechanisms being
partially due to the specific shape of the oval that causes a systematic
decoupling of a substantial number of states from the leads. Importantly a
pairwise destructive interference of the transmitting states is encountered
thereby leading to the complete conductance suppression. Coupling properties
and interferences can be tuned via a weak magnetic field. These properties are
robust with respect to the presence of disorder in the quantum dot.
