Interferometric characterization of Raman redistribution among perturbed Rydberg states of barium

Hole burning and higher-order photon effects in attosecond light-atom interaction

“…There can be other types of hole burning in two (or more) electron systems. An example involving a shortrange perturber coupled to a Rydberg series was investigated using the Ba 6snd 1,3 D 2 states perturbed by the 5d7d 1 D 2 state as the example [10,18]. As an example requiring attosecond lasers, the Be ground state is nominally 2s 2 in the valence shell.…”

“…An example involving a short range perturber coupled to a Rydberg series was investigated using the Ba 6snd 1,3 D 2 states perturbed by the 5d7d 1 D 2 state as the example. [8,13] As an example requiring attosecond lasers, the Be ground state is nominally 2s 2 in the valence shell. Calculations that include correlation have found that there is a large admixture of 2p 2 in the ground state wave function.…”

“…Hole burning was investigated in Rydberg states where the radial period can be in the picosecond regime [9,10]. For a state with energy E = −1/2ν 2 , the radial period is given by T Ryd = 2πν 3 a.u., which is T Ryd = 1.52 × 10 −4 ν 3 ps.…”

Probing Rydberg electron dynamics

“…Conversely, the inverse of a localized wave packet, an antiwave packet, has also been produced [4,[18][19][20][21][22]. When a stationary Rydberg state is exposed to optical frequency radiation, conservation of energy and momentum dictates that only that part of the electronic wavefunction which is near the nucleus can exchange energy with the optical radiation field.…”
