Metaphotonics for High-Harmonic Generation
Pavel Tonkaev, Anton Rudenko, Ziwen Wang +2
We summarise the recent advances on the generation of high-order harmonics in optical metaphotonic structures such as isolated resonators and metasurfaces. In such subwavelength-pa…

All-Optical Manipulation of Band Gap Dynamics via Electron-Phonon Coupling
Jicai Zhang, Tien-Dat Tran, Ziwen Wang +5
The electron-phonon coupling (EPC) is a ubiquitous interaction in condensed systems and plays a vital role in shaping the electronic properties of materials. Yet, achieving coheren…

High Harmonic Spectroscopy Probes Lattice Dynamics
Jicai Zhang, Ziwen Wang, Frank Lengers +5
The probing of coherent lattice vibrations in solids has been conventionally carried out using time-resolved transient spectroscopy where only the relative oscillation amplitude ca…
