Coherent Control of Quantum and Classical Correlations in Photoionization
Axel Stenquist, Jan Marcus Dahlström
The ability to control quantum correlations in strongly driven systems is a central challenge across quantum science, with implications for ultrafast dynamics, quantum control, and…
Quantitative analysis of resonant ionization by smooth laser pulses: Connection between effective Hamiltonian theory and strong-field dressed continua
Jakob Nicolai Bruhnke, Jan Marcus Dahlström
Resonant photoionization in the intense high-frequency regime can exhibit extremely asymmetric Autler-Townes doublets whose origin remains debated. It has been attributed either to…
Reconciliation of effective Hamiltonians for intense light-matter interaction
Jakob Nicolai Bruhnke, Jan Marcus Dahlström
Essential-state models are central for quantum control and technology in broad regimes of light-matter interaction. The canonical effective Hamiltonian is obtained equivalently fro…
Photoelectron spectroscopy with a resonant dichromatic field: Role of geometric phase
Evan Munaro-Langloÿs, Axel Stenquist, Jan Marcus Dahlström
We investigate geometric-phase control in resonantly driven two-level atoms exposed to near-degenerate dichromatic laser pulses. In contrast to conventional two-color schemes based…
Causality of ultrafast photoionization from argon 3s using an ab initio relativistic approach
Rezvan Tahouri, Jan Marcus Dahlström
We study real-time photoionization flux at the Amusia-Cooper minimum (ACM) in argon using \textit{ab initio} simulations with the relativistic time-dependent configuration-int…
