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…
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…
Ultrafast lattice disordering can be accelerated by electronic collisional forces
Gilberto A. de la Pena Munoz, Alfredo A. Correa, Shan Yang +11
In the prevalent picture of ultrafast structural phase transitions, the atomic motion occurs in a slowly varying potential energy surface determined adiabatically by the fast elect…
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…
Ultrafast x-ray scattering reveals composite amplitude collective mode in the Weyl charge density wave material (TaSe)I
Quynh L. Nguyen, Ryan A. Duncan, Gal Orenstein +27
We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe)I following photoexcitation with femtosecond infrared laser pulses…
Observation of a Novel Lattice Instability in Ultrafast Photoexcited SnSe
Yijing Huang, Shan Yang, Samuel Teitelbaum +11
There is growing interest in using ultrafast light pulses to drive functional materials into nonequilibrium states with novel properties. The conventional wisdom is that above gap…
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…
