Time delays in anisotropic systems
Ulf Saalmann, Jan M. Rost
Scattering properties and time delays for general (non-symmetric) potentials in terms of the respective S-matrices are discussed paradigmatically in one dimension and in comparison…
Strong-field photoionization by circularly polarized light
Jonathan Dubois, Camille Lévêque, Jérémie Caillat +3
We demonstrate that strong-field ionization of atoms driven by circularly polarized light becomes an adiabatic process when described in the frame rotating with the laser field. As…
Laser-assisted Fano resonance: attosecond quantum control and dynamical imaging
Meng Han, Hao Liang, Jia-bao Ji +4
A Fano resonance arises from the pathway interference between discrete and continuum states, playing a fundamental role in many branches of physics, chemistry and material science.…
Observation of coherent oscillations in association of dimers from a thermal gas of ultracold atoms
Roy Elbaz, Yaakov Yudkin, P. Giannakeas +3
We report the observation of coherent oscillations in conversion efficiency of weakly-bound dimers formed from a thermal gas of ultracold atoms. Finite thermal energy of the gas ca…
Symmetry-induced decoherence-free subspaces
Jonathan Dubois, Ulf Saalmann, Jan Michael Rost
Preservation of coherence is a fundamental yet subtle phenomenon in open systems. We uncover its relation to symmetries respected by the system Hamiltonian and its coupling to the…
Enhanced high-order harmonics through periodicity breaks: from backscattering to impurity states
Chuan Yu, Ulf Saalmann, Jan M. Rost
Backscattering of delocalized electrons has been recently established [Phys. Rev. A 105, L041101 (2022)] as a mechanism to enhance high-order harmonic generation (HHG) in periodic…
