We start assuming that the ‘tilting’ is very small and far from any resonance: there is no level of the lower manifold which is degenerate with some level of the upper manifold. In these conditions, there is no excitation from the lower to the upper manifold, so and . The validity of the adiabatic approximation can be ... greenwich post office hours

The adiabatic theorem is a concept in quantum mechanics. Its original form, due to Max Born and Vladimir Fock (1928), was stated as follows: A physical system remains in its instantaneous eigenstate if a given perturbation is acting on it slowly enough and if there is a gap between the eigenvalue and the rest … See more At some initial time $${\displaystyle t_{0}}$$ a quantum-mechanical system has an energy given by the Hamiltonian $${\displaystyle {\hat {H}}(t_{0})}$$; the system is in an eigenstate of For a truly adiabatic … See more Under a slowly changing Hamiltonian $${\displaystyle H(t)}$$ with instantaneous eigenstates $${\displaystyle n(t)\rangle }$$ and corresponding … See more We will now pursue a more rigorous analysis. Making use of bra–ket notation, the state vector of the system at time $${\displaystyle t}$$ can be written $${\displaystyle \psi (t)\rangle =\sum _{n}c_{n}^{A}(t)e^{-iE_{n}t/\hbar } \phi _{n}\rangle ,}$$ See more Simple pendulum As an example, consider a pendulum oscillating in a vertical plane.
