Investigation of pairing in the multi-band superconductor EuRbFe4As4 using 2e-ARPES
ORAL
Abstract
Strongly-correlated electron physics remains an area of intense intrigue in condensed matter systems. Here, we present our group's progress in two electron coincidence photoemission spectroscopy (2e-ARPES), which enables the detection of momenta and energy of correlated electrons emitted from a single incident photon. Namely, we show experimental evidence of pairing in the superconductor EuRbFe4As4, which is a member of the iron pnictide superconducting family. This experimental technique holds tremendous promise for answering many outstanding key condensed matter physics questions, such as the pairing mechanisms of unconventional superconductors.
