“…Examples of bistable systems occur in areas such as physics [bistable super-conducting quantum interface device (SQUID) loops [29], bidirectional ring lasers [17]], biology (sensory systems [28], [30]), Earth sciences [climate [14], [29], [36]] and electronics (Schmitt trigger [16], tunnel diode [37], [38]). Here, a simple double well potential in a nonlinear system is described [16], [18], [23], [39].…”
