Disentangling High Harmonic Generation from Surface and Bulk States of a Topological Insulator
Sha Li, Wenyi Zhou, Kazi A. Imroz +9
The discovery of topological phases has introduced a new dimension to materials science. Three-dimensional (3D) topological insulators (TIs) are a remarkable class of matter that i…
Ultrafast Decoherence of Charge Density Waves in KMoO
Rafael T. Winkler, Larissa Boie, Yunpei Deng +20
Recent works have suggested that transient suppression of a charge density wave (CDW) by an ultra-short excitation can lead to an inversion of the CDW phase. We experimentally inve…
High-power femtosecond mid-IR source with tunable center frequency and chirp
Larissa Boie, Benjamin H. Strudwick, Rafael T. Winkler +2
We present an experimental implementation of a chirped mid-infrared (mid-IR) high-power laser source with variable center frequency between 4 THz to 30 THz and continuously tunable…
Terahertz displacive excitation of a coherent Raman-active phonon in VO
Flavio Giorgianni, Mattia Udina, Tommaso Cea +7
Nonlinear processes involving frequency-mixing of light fields set the basis for ultrafast coherent spectroscopy of collective modes in solids. In certain semimetals and semiconduc…
Photoinduced structural dynamics of multiferroic TbMnO
Elsa Abreu, Matteo Savoini, Larissa Boie +17
We use time-resolved hard x-ray diffraction to investigate the structural dynamics of the multiferroic insulator TbMnO in the low temperature antiferromagnetic and ferroelectri…
Comparison of coherent phonon generation by electronic and ionic Raman scattering in LaAlO
Martin J. Neugebauer, Dominik M. Juraschek, Matteo Savoini +5
In ionic Raman scattering, infrared-active phonons mediate a scattering process that results in the creation or destruction of a Raman-active phonon. This mechanism relies on nonli…
Correlation between electronic and structural orders in 1T-TiSe2
Hiroki Ueda, Michael Porer, José R. L. Mardegan +11
The correlation between electronic and crystal structures of 1T-TiSe2 in the charge density wave (CDW) state is studied by x-ray diffraction. Three families of reflections are used…
