- Suppose I have some classical equations of motion of the form dL/dt = F(L),
- where L is the angular momentum vector and F is a vector field. Further
- suppose that F contains a nasty dissipative term. Is there a direct way
- to get the corresponding quantum mechanical equations of motion? Do I
- try to go Lagrangian->Hamiltonian->dL/dt = i h_bar [L, H] (i/h_bar? h_bar/i?)
- I vaguely remember that having a dissipative Hamiltonian does bad things
- in quantum mechanics.
-
- Actually, if somebody could just point me towards a book that would answer
- these questions, it would be appreciated muchly.
