Shortcuts to adiabaticity in waveguide couplers–theory and implementation

AK Taras, A Tuniz, MA Bajwa, V Ng… - … in Physics: X, 2021 - Taylor & Francis
Adiabatic processes are ubiquitous in physics and engineering. A drawback of such
processes is that they tend to be slow, either in time–for atomic systems, for example–or in …

Adiabatic passage to the continuum: controlling ionization with chirped laser pulses

U Saalmann, SK Giri, JM Rost - Physical Review Letters, 2018 - APS
We demonstrate that, by changing the direction of the chirp in vacuum-ultraviolet pulses, one
can switch between excitation and ionization with very high contrast, if the carrier frequency …
