Measuring momentum-resolved dissipation of phonon-polaritons in LiNbO with terahertz driving
Megan F. Biggs, Rossella Acampora, Niccolò Sellati +5
Mapping the dispersion of polaritons, hybrid quasiparticles arising from light-matter coupling, can provide key insights into the material dielectric response, coupling strength, a…

Tuning chirality amplitude at ultrafast timescales
Hiroki Ueda, Takahiro Sato, Quynh L. Nguyen +12
Chirality is a fundamental symmetry concept describing discrete states, i.e., left-handed, right-handed, or achiral, and existing at disparate scales and in many categories of scie…

Roles of band gap and Kane electronic dispersion in the THz-frequency nonlinear optical response in HgCdTe
Davide Soranzio, Elsa Abreu, Sarah Houver +7
Materials with linear electronic dispersion often feature high carrier mobilities and unusually strong nonlinear optical interactions. In this work, we investigate the THz nonlinea…
