Long Living Hot and Dense Plasma from Relativistic Laser-Nanowire Array Interaction
Ehsan Eftekhari-Zadeh, Mikhail Gyrdymov, Parysatis Tavana +13
Long-living, hot and dense plasmas generated by ultra-intense laser beams are of critical importance for laser-driven nuclear physics, bright hard X-ray sources, and laboratory ast…
Ultrafast Coherent Bandgap Modulation Probed by Parametric Nonlinear Optics

Light-matter interactions in crystals are powerful tools that seamlessly allow both functionalities of sizeable bandgap modulation and non-invasive spectroscopy. While we often ass…
Unveiling the Role of Electron-Phonon Scattering in Dephasing High-Order Harmonics in Solids
Viacheslav Korolev, Thomas Lettau, Vipin Krishna +8
High-order harmonic generation (HHG) in solids is profoundly influenced by the dephasing of the coherent electron-hole motion driven by an external laser field. The exact physical…
