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…
Terahertz time-domain spectroscopy of materials under high pressure in a diamond anvil cell
Tim Suter, Zia Macdermid, Zekai Chen +2
We present the combination of a broadband terahertz time-domain spectroscopy system (0.1 - 8 THz), a diamond anvil cell capable of generating high pressure conditions of up to 10 G…
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…
Ultrafast selective mid-infrared sublattice manipulation in the ferrimagnet
Davide Soranzio, Matteo Savoini, Fabian Graf +6
is a ferrimagnet with two oppositely ordered spin sublattices (Fe and Cr), connected via superexchange interaction, giving a non-zero net magnetic moment. We show, usin…
