Topics in adiabaticity

• This paper presents the general framework for adiabatic time evolution. It discusses two cases where systematic sequences of approximations are possible: the time-dependent two-level system and the harmonic oscillator with drifting frequency. In the former case, the appearance of a level crossing leads to nonanalytic corrections not captured by the systematic expansion.
