Hi
Can someone please explain the answer to the following thread? I tried uncoupling the Hamiltonian but to no avail. http://www.physicsforums.com/showthread.php?t=602106 Thank you.

Did you try the proposed rotation?
##x'=\cos(\alpha)x + \sin(\alpha)y##, ##y'=\sin(\alpha)x + \cos(\alpha)y## Where α has to be determined to uncouple the Hamiltonian.

You could show your work here, this would help to find the error.
