Since most strong-field observables relate to the continuum portion of the wave function, the boundaries of the grid---which act as hard walls and thus cause reflection---can substantially impact the observables ...
By comparing with previous widely used absorbing potentials, we find a factor of 3--4 reduction in the absorption range, given the same level of absorption over a specified energy interval. ...
Among the various methods to effect absorption at the boundary, the most widely used -and probably the simplest -method is the complex absorbing potential (CAP) [4] [5] [6] [7] [8] [9] [10] [11] [12] ...
