    "abstract": "We present experimental study of a topological excitation, {\\it interface},\nin a vertically vibrated layer of granular material. We show that these\ninterfaces, separating regions of granular material oscillation with opposite\nphases, can be shifted and controlled by a very small amount of an additional\nsubharmonic signal, mixed with the harmonic driving signal. The speed and the\ndirection of interface motion depends sensitively on the phase and the\namplitude of the subharmonic driving.",
