Sub-cycle doublon-holon dynamics in one-dimensional Mott insulators revealed by two-color high-harmonic spectroscopy
Lance Hatch, Aditya Verma, Eric Schultz +7
Solid-state high-harmonic spectroscopy is becoming an emerging tool for probing nonequilibrium many-body dynamics. Yet, direct measurements of strongly driven, sub-optical-cycle dy…
Ultrafast measurements of mode-specific deformation potentials of BiTe and BiSe
Yijing Huang, José D. Querales-Flores, Samuel W. Teitelbaum +24
Quantifying electron-phonon interactions for the surface states of topological materials can provide key insights into surface-state transport, topological superconductivity, and p…
Ab Initio Prediction of Excited State and Polaron Effects in Transient XUV Measurements of -FeO
Isabel M. Klein, Hanzhe Liu, Danika Nimlos +2
Transient X-ray and extreme ultraviolet (XUV) spectroscopies have become invaluable tools for studying photoexcited dynamics due to their sensitivity to carrier occupations and loc…
Measuring photoexcited electron and hole dynamics in ZnTe and modeling excited state core-valence effects in transient XUV reflection spectroscopy
Hanzhe Liu, Jonathan M. Michelsen, Isabel M. Klein +1
Transient XUV spectroscopy is growing in popularity for the measurement of solar fuel and photovoltaic materials as it can separately measure electron and hole energies for multipl…
Element-specific electronic and structural dynamics using transient X-ray spectroscopy
Hanzhe Liu, Isabel M. Klein, Jonathan M. Michelsen +1
Transient X-ray absorption techniques can measure ultrafast dynamics of the elemental edges in a material or multiple layer junction, giving them immense potential for deconvolutin…
Entangled light-matter interactions and spectroscopy
Szilard Szoke, Hanzhe Liu, Bryce P. Hickam +2
Entangled photons exhibit non-classical light-matter interactions that create new opportunities in materials and molecular science. For example, in entangled two-photon absorption,…
Attosecond synchronization of extreme ultraviolet high harmonics from crystals
Giulio Vampa, Jian Lu, Yong Sing You +7
The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength range. These observatio…
Measurements of Nonequilibrium Interatomic Forces in Photoexcited Bismuth
Samuel W. Teitelbaum, Thomas C. Henighan, Hanzhe Liu +11
We determine experimentally the excited-state interatomic forces in photoexcited bismuth. The forces are obtained by a constrained least-squares fit of the excited-state dispersion…
Overcoming the absorption limit in high-harmonic generation from crystals
Hanzhe Liu, Giulio Vampa, Jingyuan Linda Zhang +6
Since the new millennium coherent extreme ultra-violet and soft x-ray radiation has revolutionized the understanding of dynamical physical, chemical and biological systems at the e…
High-harmonic generation from an epsilon-near-zero material
Yuanmu Yang, Jian Lu, Alejandro Manjavacas +7
High-harmonic generation (HHG) from a compact, solid-state medium is highly desirable for applications such as coherent attosecond pulse generation and extreme ultra-violet (EUV) s…
Coherent order parameter dynamics in SmTe
M. Trigo, P. Giraldo-Gallo, M. E. Kozina +13
We present a combined ultrafast optical pump-probe and ultrafast x-ray diffraction measurement of the CDW dynamics in SmTe at 300 K. The ultrafast x-ray diffraction measurement…
Direct Measurement of Anharmonic Decay Channels of a Coherent Phonon
Samuel W. Teitelbaum, Tom Henighan, Yijing Huang +12
We observe anharmonic decay of the photoexcited coherent A1g phonon in bismuth to points in the Brillouin zone where conservation of momentum and energy are satisfied for three-pho…
Enhanced High-Harmonic Generation from an All-Dielectric Metasurface
Hanzhe Liu, Cheng Guo, Giulio Vampa +7
The recent observation of high-harmonic generation from solids creates a new possibility for engineering fundamental strong-field processes by patterning the solid target with subw…
