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…
Quenched lattice fluctuations in optically driven SrTiO3
M. Fechner, M. Först, G. Orenstein +12
Many functionally relevant ferroic phenomena in quantum materials can be manipulated by driving the lattice coherently with optical and terahertz pulses. New physical phenomena and…
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…
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…
Generic character of charge and spin density waves in superconducting cuprates
Sangjun Lee, Edwin W. Huang, Thomas A. Johnson +19
Understanding the nature of charge density waves (CDW) in cuprate superconductors has been complicated by material specific differences. A striking example is the opposite doping d…
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 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…
Unconventional Charge Density Wave Order in the Pnictide Superconductor Ba(NiCo)As
Sangjun Lee, Gilberto de la Pena, Stella X. -L. Sun +10
Ba(NiCo)As is a structural homologue of the pnictide high temperature superconductor, Ba(FeCo)As, in which the Fe atoms are replaced by Ni.…
Observation of a Charge Density Wave Incommensuration Near the Superconducting Dome in CuxTiSe2
Anshul Kogar, Gilberto A. de la Pena, Sangjun Lee +8
X-ray diffraction was employed to study the evolution of the charge density wave (CDW) in CuxTiSe2 as a function of copper intercalation in order to clarify the relationship betwee…
A reexamination of the effective fine structure constant of graphene, as measured in graphite
Yu Gan, Gilberto de la Pena Munoz, Anshul Kogar +5
We present a refined and improved study of the influence of screening on the effective fine structure constant of graphene, , as measured in graphite using inelastic x-ray sca…
Influence of Ti doping on the incommensurate charge density wave in 1T-TaS2
X. M. Chen, A. J. Miller, C. Nugroho +10
We report temperature-dependent transport and x-ray diffraction measurements of the influence of Ti hole doping on the charge density wave (CDW) in 1T-Ta(1-x)Ti(x)S(2). Confirming…
Emergence of charge density wave domain walls above the superconducting dome in TiSe2
Y. I. Joe, X. M. Chen, P. Ghaemi +11
Superconductivity (SC) in so-called "unconventional superconductors" is nearly always found in the vicinity of another ordered state, such as antiferromagnetism, charge density wav…
