Light-induced trion-exciton competition revealed by ultrafast photoemission
Ittai Sidilkover, Nir Hen Levin, Yuval Nitzav +11
Strong Coulomb interactions in low-dimensional quantum materials give rise to emergent bound states such as excitons and trions. Trions are conventionally secondary excitations, re…
Trion gas on the surface of a failed excitonic insulator
Yuval Nitzav, Abigail Dishi, Himanshu Lohani +15
Trions, three-body bound states composed of an exciton and an additional charge, are typically fragile and require external excitation to form. Here, we report the spontaneous emer…
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…
