parametric excitation from the quantum ground state leads to the generation of quantum squeezed states. These equations are similar to bosonic Josephson junction equations describing the double ...

An object is moving counter-clockwise along a circle with the centre at the origin. At \(t=0\) the object is at point \(A(0,5)\) and at \(t=2\pi\) it is back to point \(A\) for the first time.

At \(t=0\) the object is at point \(A(0,5)\) and at \(t=2\pi\) it is back to point \(A\) for the first time. Determine the parametric equations \(x=f(t)\text{,}\) \(y=g(t)\) that describe the motion ...
