Shortcuts to adiabaticity (STA) is a protocol to speed up the quantum adiabatic process through nonadiabatic routes. Time-dependent oscillators, whose specta generate algebra so(2; 1) ≈ su(1; 1) give quantum invariants and thereby exact quantum states, exhibit a variety of processes from adiabatic to nonadiabatic evolutions. To illustrate how time-dependent oscillators realize the STA, first we use the construction method of an Ermakov-Pinney invariant and find the associated time-dependent oscillator. Then, we introduce a class of time-dependent oscillators whose wave functions are known, and find the condition for the STA for adiabatic and nonadiabatic evolutions.
