Classical ballistic transport in a triangular shaped cavity — •Martin Richter and Roland Ketzmerick — Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden, Germany

Recent magneto-resistance measurements on semiconductor heterostructures with a triangular shaped gate revealed an unexpected splitting of a commensurability peak [D. Maryenko et al., unpublished]. We explain this splitting in the context of classical ballistic transport. The importance of the phase-space structure, width of the openings, and softness of the potential is stressed.
