Nonresonant optomechanical control of structural phases
Jiaojian Shi, Yijing Huang, Christian Heide +24
Optical tweezers demonstrate how light can exert forces to trap, repel, and manipulate microscopic particles without absorption. Recent theory has suggested that such forces can ex…
Emergent Antiphase Stacking in a Transient Charge Density Wave
Jade Stanton, Gal Orenstein, Ryan A. Duncan +14
Photoexcitation can induce novel states in materials that are inaccessible in equilibrium, a recent example being the light-induced charge density wave (CDW) observed in $\text{LaT…
A textured polar phase in strained SrTiO3
Huaiyu Hugo Wang, Ernesto Flores, Jade Stanton +11
Quantum materials can harbour hidden phases whose microscopic structures differ from conventional ordered states while reproducing their macroscopic signatures, making them easy to…
Second-order microscopic nonlinear susceptibility in a centrosymmetric material: application to imaging valence electron motion
Chance Ornelas-Skarin, Tatiana Bezriadina, Matthias Fuchs +10
We report measurements of phase-matched nonlinear x-ray and optical sum-frequency generation from single-crystal silicon using sub-resonant 0.95 eV laser pulses and 9.5 keV hard x-…
Nanoscale Ultrafast Lattice Modulation with Hard X-ray Free Electron Laser
Haoyuan Li, Nan Wang, Leon Zhang +24
Understanding and controlling microscopic dynamics across spatial and temporal scales has driven major progress in science and technology over the past several decades. While ultra…
Nonresonant Raman control of ferroelectric polarization
Jiaojian Shi, Christian Heide, Haowei Xu +15
Important advances have recently been made in the search for materials with complex multi-phase landscapes that host photoinduced metastable collective states with exotic functiona…
Terahertz-induced tunnel ionization drives coherent Raman-active phonon in Bismuth
Bing Cheng, Patrick L. Kramer, Mariano Trigo +6
Driving coherent lattice motion with THz pulses has emerged as a novel pathway for achieving dynamic stabilization of exotic phases that are inaccessible in equilibrium quantum mat…
Observation of polarization density waves in SrTiO3
Gal Orenstein, Viktor Krapivin, Yijing Huang +23
The nature of the "failed" ferroelectric transition in SrTiO3 has been a long-standing puzzle in condensed matter physics. A compelling explanation is the competition between ferro…
Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO and KTaO
Yijing Huang, Peihao Sun, Samuel W. Teitelbaum +21
We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe sca…
Ultrafast measurements under anisotropic strain reveal near equivalence of competing charge orders in TbTe
Soyeun Kim, Gal Orenstein, Anisha G. Singh +3
We report ultrafast reflectivity measurements of the dynamics of the order parameter of the charge density wave (CDW) in TbTe under anisotropic strain. We observe an increase i…
Ultrafast Suppression of the Ferroelectric Instability in KTaO
Viktor Krapivin, Mingqiang Gu, D. Hickox-Young +13
We use an x-ray free-electron laser to study the ultrafast lattice dynamics following above band-gap photoexcitation of the incipient ferroelectric potassium-tantalate, \kto. % We…
Direct Observation of Coherent Longitudinal and Shear Acoustic Phonons in TaAs Using Ultrafast X-ray Diffraction
Min-Cheol Lee, N. Sirica, S. W. Teitelbaum +18
Using femtosecond time-resolved X-ray diffraction, we investigated optically excited coherent acoustic phonons in the Weyl semimetal TaAs. The low symmetry of the (112) surface pro…
Photoinduced suppression of the ferroelectric instability in PbTe
M. P. Jiang, M. Trigo, S. Fahy +18
The interactions between electrons and phonons drive a large array of technologically relevant material properties including ferroelectricity, thermoelectricity, and phase-change b…
