Phase Transition in Two Terminal Electrical Circuit
Yasuo Morimoto · Journal of the Physical Society of Japan · 1981
The phase transition phenomenon is found in two terminal electrical circuit. I-V curve of the circuit consists of five regions, ON, OFF, I, II and III-states. The ON and OFF-states produce only DC-current. The I and III-states have decaying oscillations. In the II-state a constant amplitude oscillation appears. As the bias passes the upper and lower boundaries of the II-state the increases in the current noise and in the decay time of the decaying oscillation are observed, which correspond to the critical fluctuation and critical slowing down, respectively.
