Abstract
While the static-capacitance matrix is always symmetric and thus an even function of the magnetic field, the dynamic-capacitance matrix of multiterminal samples obeys in general only the weaker Onsager-Casimir symmetry relations. Our results are in accordance with recent experimental observations of asymmetric dynamic capacitances in quantized Hall systems. We predict quantization of the four-terminal resistances of an insulating Hall sample.
