High Resolution Angle Resolved Photoemission with Tabletop 11eV Laser
Yu He, Inna Vishik, Ming Yi +12
We developed a table-top vacuum ultraviolet (VUV) laser with nm wavelength (10.897eV) and demonstrated its viability as a photon source for high resolution angle-resolved…
Thickness-Dependent Coherent Phonon Frequency in Ultrathin FeSe/SrTiO Films
Shuolong Yang, Jonathan A. Sobota, Dominik Leuenberger +7
Ultrathin FeSe films grown on SrTiO substrates are a recent milestone in atomic material engineering due to their important role in understanding unconventional superconducti…
Inequivalence of Single-Particle and Population Lifetimes in a Cuprate Superconductor
Shuolong Yang, Jonathan A. Sobota, Dominik Leuenberger +6
We study optimally doped Bi-2212 (~K) using femtosecond time- and angle-resolved photoelectron spectroscopy. Energy-resolved population lifetimes are extracted and…
Classification of Collective Modes in a Charge Density Wave by Momentum-Dependent Modulation of the Electronic Band Structure
D. Leuenberger, J. A. Sobota, S. -L. Yang +7
We present time- and angle-resolved photoemission spectroscopy measurements on the charge density wave system CeTe. Optical excitation transiently populates the unoccupied ba…
