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…
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…
All-optical probe of three-dimensional topological insulators based on high-harmonic generation by circularly-polarized laser fields
Denitsa Baykusheva, Alexis Chacón, Jian Lu +9
We report the observation of a novel nonlinear optical response from the prototypical three-dimensional topological insulator BiSe through the process of high-order harmoni…
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…
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…
