All-optical probe of three-dimensional topological insulators based on high-harmonic generation by circularly-polarized laser fields
Denitsa Baykusheva, Alexis Chacón, Jian Lu +9
We report the observation of a novel nonlinear optical response from the prototypical three-dimensional topological insulator BiSe through the process of high-order harmoni…
Theory for all-optical responses in topological materials: the velocity gauge picture
Dasol Kim, Dongbin Shin, Alexandra S. Landsman +2
High Harmonic Generation (HHG), which has been widely used in atomic gas, has recently expanded to solids as a means to study highly nonlinear electronic response in condensed matt…
Quantum interference and imaging using intense laser fields
Kasra Amini, Alexis Chacón, Sebastian Eckart +2
The interference of matter waves is one of the intriguing features of quantum mechanics that has impressed researchers and laymen since it was first suggested almost a century ago.…
Strong-field physics in three-dimensional topological insulators
Denitsa Baykusheva, Alexis Chacón, Dasol Kim +3
We investigate theoretically the strong-field regime of light-matter interactions in the topological-insulator class of quantum materials. In particular, we focus on the process of…
Optical turbulence profiling with Stereo-SCIDAR for VLT and ELT
J. Osborn, R. W. Wilson, M. Sarazin +11
Knowledge of the Earth's atmospheric optical turbulence is critical for astronomical instrumentation. Not only does it enable performance verification and optimisation of existing…
Restricted space ab initio models for double ionization by strong laser pulses
Dmitry K. Efimov, Artur Maksymov, Jakub S. Prauzner-Bechcicki +5
Double electron ionisation process occurs when an intense laser pulse interacts with atoms or molecules. Exact {\it ab initio} numerical simulation of such a situation is extremely…
High-order harmonic generation in atomic and molecular systems
Noslen Suárez, Alexis Chacón, Jose A. Pérez-Hernández +3
High-order harmonic generation (HHG) results from strong-field laser matter interaction and it is one of the main processes that are used to extract electron structural and dynamic…
Wannier-Bloch approach to localization in high harmonics generation in solids
Edyta N. Osika, Alexis Chacón, Lisa Ortmann +7
Emission of high-order harmonics from solids provides a new avenue in attosecond science. On one hand, it allows to investigate fundamental processes of the non-linear response of…
Above-threshold ionization and photoelectron spectra in atomic systems driven by strong laser fields
Noslen Suárez, Alexis Chacón, Marcelo Ciappina +2
Above-threshold ionization (ATI) results from strong field laser-matter interaction and it is one of the fundamental processes that may be used to extract electron structural and d…
Numerical studies of light-matter interaction driven by plasmonic fields: the velocity gauge
A. Chacón, M. Lewenstein, M. F. Ciappina
Theoretical approaches to strong field phenomena driven by plasmonic fields are based on the length gauge formulation of the laser-matter coupling. From the theoretical viewpoint i…
