As it happens that the following commutation relation is 4. Retrieved from ” https: To find the conditions on the constants u and v such that the transformation is canonical, the commutator is evaluated, viz.
On the theory of superfluidityJ. Also in nuclear physicsthis method is applicable since it may describe the “pairing energy” of transformatio in a heavy element.
