Universal shortcuts to adiabaticity of finite-time and weak processes

Abstract: The analytical expression for shortcuts to adiabaticity for any switching time and any thermally isolated system performing a finite-time and weak process is presented. It is based on the universal solution of the optimal protocols of weak processes, where the extension to adiabatic processes was made by means of the concept of waiting time. Two examples are solved to verify the validity of such shortcuts: the typical case of oscillatory relaxation function and the transverse-field quantum Ising chain. In the end, a discussion about the limitations of the applicability of these shortcuts in quantum annealing is made.
