Rainbow RABBITT as a Probe of Coherent Rabi Dynamics
Vladislav V. Serov, Anatoli S. Kheifets
Attosecond pulse trains interacting with a resonantly dressed atom generate a pronounced intra-sideband phase structure that remains hidden in conventional spectrally integrated RA…
Circular RABBITT goes under threshold
Vladislav V. Serov, Jia-Bao Ji, Meng Han +3
We introduce circular under-threshold RABBITT (cuRABBITT) as a new interferometric method to probe discrete electronic excitations in atoms with attosecond resolution. By combining…
Crossover between the zeptosecond and attosecond physics
T. Nandi, Yash Kumar, Adya P. Mishra +7
Nuclear orbiting resonances have been revealed at the sub-barrier energies as an atomic phenomenon by means of x-ray spectroscopy experiments. This interpretation is supported by s…
Zeptosecond to attosecond dynamics in atoms and possibility of generating a zeptosecond light source
T. Nandi, Soumya Chatterjee, Adya P. Mishra +3
In nuclear collisions, nuclear bremsstrahlung can cause nuclear Coulomb excitation via photon exchange in the projectile as well as the target nuclei. Such a process originating in…
Continuous rainbow RABBITT investigation of resonant states in He and H
Vladislav Serov, Anatoli Kheifets
We employ Reconstruction of Attosecond Beating By Interference of Two-photon Transitions with an advanced energy resolution (rainbow RABBITT) to resolve under-threshold discrete ex…
Double--hole resonances in single photoionization of He-like B ions
A. Müller, P. -M. Hillenbrand, S. -X. Wang +8
Within a joint experimental and theoretical research project, single photoionization of He-like B ions was investigated in the energy range from approximately 250 to 1200~eV…
Tracking quantum clouds expansion in tunneling ionization
I. A. Ivanov, A. S. Kheifets, Kyung Taec Kim
We study formation and evolution of the electron wave-packets in the process of strong field ionization of various atomic targets. Our study is based on reformulating the problem i…
Relation Between Photoionisation Cross Sections and Attosecond Time Delays
Jia-Bao Ji, Anatoli S. Kheifets, Meng Han +2
Determination and interpretation of Wigner-like photoionisation delays is one of the most active fields of attosecond science. Previous results have suggested that large photoionis…
Phase retrieval from angular streaking of XUV atomic ionization
Anatoli S. Kheifets, Rickson Wielian, Igor A. Ivanov +3
We demonstrate an accurate phase retrieval of XUV atomic ionization by streaking the photoelectron in a circularly polarized IR laser field. The streaking phase can then be convert…
Time-dependent calculations of transfer ionization by fast proton-helium collision in one-dimensional kinematics
Vladislav V. Serov, A. S. Kheifets
We analyze a transfer ionization (TI) reaction in the fast proton-helium collision by solving a time-dependent Schrödinger equation (TDSE) un…
Extraction of attosecond time delay using the soft photon approximation
I. A. Ivanov, A. S. Kheifets
We use the soft photon approximation to extract the Wigner time delay from atomic two-color photoionization experiments. Unlike the strong field approximation, the present method d…
Timing analysis of two-electron photoemission
A. S. Kheifets, I. A. Ivanov, Igor. Bray
We predict a significant delay of two-electron photoemission from the helium atom after absorption of an attosecond XUV pulse. We establish this delay by solving the time dependent…
Lippmann-Schwinger description of multiphoton ionization
I. A. Ivanov, A. S. Kheifets
We outline a formalism and develop a computational procedure to treat the process of multiphoton ionization (MPI) of atomic targets in strong laser fields. We treat the MPI process…
Convergent calculations of double ionization of helium: from (,2e) to (e,3e) processes
A. S. Kheifets, Igor Bray
The first absolute (e,3e) measurements, by Lahmam-Bennani et al [Phys. Rev. A {\bf 59}, 3548 (1999)], have been recently approximately reproduced by Berakdar [Phys. Rev. Lett. {\bf…
