WebClosed 10 years ago. Let V ( x) = − u δ ( x) − v δ ( x − a) where u, v > 0 correspond to a potential with two δ wells. Let v > u. If a is very large, there is certainly a bound state: the particle sits in the δ -well. As a decreases to a certain critical value, the bound state disappears. I need help finding that value. WebFor ω 0 ²<0 (so ω 0 is pure imaginary), the Duffing oscillator describes the dynamics of a point mass in a double well potential, and it can be regarded as a model of a periodically forced steel beam which is deflected toward the two magnets. It is known that chaotic motions can be observed in this case. braided banana leaf mirror
