Coherent Phonon Generation from Prethermal Carrier Populations in a Semiconductor
Mingyu Shi, Matteo Savoini, Patrick Friebel +5
Ultrafast laser excitation of carriers in semiconductors often results in the creation of fully symmetric coherent optical phonons, typically understood in terms of a thermalized t…
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…
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…
2D THz spectroscopic investigation of ballistic conduction-band electron dynamics in InSb
S. Houver, L. Huber, M. Savoini +2
Using reflective cross-polarized 2D THz time-domain spectroscopy in the range of 1-12 THz, we follow the trajectory of the out-of-equilibrium electron population in the low-bandgap…
