Formation of buried domain walls in the ultrafast transition of SmTe
M. Trigo, P. Giraldo-Gallo, J. N. Clark +13
We study ultrafast x-ray diffraction on the charge density wave (CDW) of SmTe using an x-ray free electron laser. The CDW peaks show that photoexcitation with near-infrared pum…
Quantum well states in fractured crystals of the heavy fermion material CeCoIn
Nicolas Gauthier, Jonathan A. Sobota, Makoto Hashimoto +6
Quantum well states appear in metallic thin films due to the confinement of the wave function by the film interfaces. Using angle-resolved photoemission spectroscopy, we unexpected…
Low work function in the 122-family of iron-based superconductors
H. Pfau, H. Soifer, J. A. Sobota +8
We determine the work functions of the iron arsenic compounds FeAs () using photoemission spectroscopy to be 2.7 eV for CaFeAs, 1.8 eV for…
Mode-selective coupling of coherent phonons to the Bi2212 electronic band structure
S. -L. Yang, J. A. Sobota, Y. He +5
Cuprate superconductors host a multitude of low-energy optical phonons. Using time- and angle-resolved photoemission spectroscopy, we study coherent phonons in BiSrCa$_…
Revealing the Coulomb interaction strength in a cuprate superconductor
S. -L. Yang, J. A. Sobota, Y. He +10
We study optimally doped BiSrCaYCuO (Bi2212) using angle-resolved two-photon photoemission spectroscopy. Three spectral features are res…
Direct characterization of photo-induced lattice dynamics in BaFe2As2
S. Gerber, K. W. Kim, Y. Zhang +21
Ultrafast light pulses can modify the electronic properties of quantum materials by perturbing the underlying, intertwined degrees of freedom. In particular, iron-based superconduc…
