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 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…
Dynamical Scaling Reveals Topological Defects and Anomalous Evolution of a Photoinduced Phase Transition
Gal Orenstein, Ryan A. Duncan, Gilberto A. de la Pena Munoz +13
Nonequilibrium states of quantum materials can exhibit exotic properties and enable unprecedented functionality and applications. These transient states are inherently inhomogeneou…
Determination of nonthermal bonding origin of a novel photoexcited lattice instability in SnSe
Yijing Huang, Samuel Teitelbaum, Shan Yang +10
Interatomic forces that bind materials are largely determined by an often complex interplay between the electronic band-structure and the atomic arrangements to form its equilibriu…
Influence of local symmetry on lattice dynamics coupled to topological surface states
Jonathan A. Sobota, Samuel W. Teitelbaum, Yijing Huang +18
We investigate coupled electron-lattice dynamics in the topological insulator Bi2Te3 with time-resolved photoemission and time-resolved x-ray diffraction. It is well established th…
