Question: In the problem of the three coupled pendula, consider the three coupling constants as distinct, so that the potential energy may be written as with

In the problem of the three coupled pendula, consider the three coupling constants as distinct, so that the potential energy may be written as with ε12, ε13, ε23 all different.


U = (0} + 03 + 03 – 28120,62 - 2€10,0, - 2e 230 20 3)

Show that no degeneracy occurs in such a system. Show also that degeneracy can occur only if ε12 = ε13 = ε23.

U = (0} + 03 + 03 28120,62 - 210,0, - 2e 230 20 3)
