Multiple Schrödinger pictures and dynamics in shortcuts to adiabaticity
S. Ibáñez, Xi Chen, E. Torrontegui +2
A Schrödinger equation may be transformed by unitary operators into dynamical equations in different interaction pictures which share with it a common physical frame, i.e., the sam…

Transitionless quantum drivings for the harmonic oscillator
J. G. Muga, X. Chen, Ibáñez +2
Two methods to change a quantum harmonic oscillator frequency without transitions in a finite time are described and compared. The first method, a transitionless-tracking algorithm…
