摘要
Recent experiments have shown that the resonant tunneling diode in a tilted magnetic field is a new and promising probe of quantum chaos. We show that by using a scaling transformation a quantum spectrum is obtained that corresponds to a single classical regime and may be reliably analyzed in terms of periodic orbits. We show that for parameters close to experimental values (with an injection energy of about 25% of that due to the voltage drop), with increasing tilt angle, the disappearance of one set of fluctuations in the tunneling current is associated with a confluence where two periodic orbits are absorbed, persisting briefly in the spectrum as a ''ghost.''
