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…
Disentangling spin polarization from driven circular ionic motion in EuTiO
Clifford J. Allington, Matthew J. Lutz, Enoch +31
Coherently driven circular ionic motion has been reported to produce large helicity-dependent optical responses attributed to transient magnetization. However, the microscopic natu…
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…
Unveiling low THz Dynamics of Liquid Crystals: Identification of Intermolecular Interaction among Intramolecular Modes
Patrick Friebel, Daria Ruth Galimberti, Matteo Savoini +1
Liquid crystal based technologies have found considerably diversified uses and areas of application over the last few decades, proving to be excellent materials for tunable optical…
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…
