핵심 개념
While limited in revealing the inner-pair structure of two-body correlations, (γ, 2e) photoemission measurements can effectively probe the center-of-mass physics of correlated electrons, offering potential applications in studying Cooper pairs in superconductors.
인용구
"The (γ, 2e) photoemission technique has been developed to investigate the two-body correlations of the target correlated electrons."
"The coincidence detection probability of the two emitted electrons in the (γ, 2e) photoemission measurement is shown to be relevant to a two-body Bethe-Salpeter wave function, which describes the dynamical two-body correlations of the target correlated electrons near the Fermi energy."
"Thus, the (γ, 2e) photoemission technique can provide the center-of-mass physics of the two-body correlations of the target correlated electrons. It will be one potential technique to study the center-of-mass physics of the Cooper pairs in superconductor."
