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…
Octahedral and polar phase transitions in freestanding films of SrTiO3
Ludmila Leroy, Shih-Wen Huang, Chun-Chien Chiu +7
From extreme strain to bending, the possibilities in the manipulation of freestanding films of oxide perovskites bring a novel landscape to their properties and brings them one ste…
Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Impact ionization in low-band-gap semiconductors driven by ultrafast THz excitation: beyond the ballistic regime
Simone Biasco, Florence Burri, Sarah Houver +3
Using two-dimensional THz spectroscopy in combination with numerical models, we investigate the dynamics linked to carrier multiplication caused by high-field THz excitation of the…
Solid-State Biased Coherent Detection of Ultra-Broadband Terahertz Pulses for high repetition rate, low pulse energy lasers
Tim Suter, Alessandro Tomasino, Matteo Savoini +3
We report the coherent generation and detection of terahertz (THz) pulses covering the bandwidth of 0.1-9 THz in a high repetition rate, low pulse energy laser system. In this work…
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…
The Ultrafast Einstein-De Haas Effect
Christian Dornes, Yves Acremann, Matteo Savoini +20
The original observation of the Einstein-de Haas effect was a landmark experiment in the early history of modern physics that illustrates the relationship between magnetism and ang…
Triply degenerate nodal points in RERhGe (RE=Y, La, Lu)
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
As a new type of fermions without counterpart in high energy physics, triply degenerate fermions show exotic physical properties, which are represented by triply degenerate nodal p…
Domain size effects on the dynamics of a charge density wave in 1T-TaS2
G. Lantz, C. Laulhé, S. Ravy +11
Recent experiments have shown that the high temperature incommensurate (I) charge density wave (CDW) phase of 1T-TaS2 can be photoinduced from the lower temperature, nearly commens…
Ultrafast THz Field Control of Electronic and Structural Interactions in Vanadium Dioxide
A. X. Gray, M. C. Hoffmann, J. Jeong +34
Vanadium dioxide, an archetypal correlated-electron material, undergoes an insulator-metal transition near room temperature that exhibits electron-correlation-driven and structural…
