| contents | It is one challenge to develop experimental techniques for direct detection of the many-body correlations of strongly correlated electrons, which exhibit a variety of unsolved mysteries. In this article, we present a \textit{post-experiment} coincidence counting method and propose two \textit{post-experiment} coincidence detection techniques, \textit{post-experiment} coincidence angle-resolved photoemission spectroscopy (cARPES) and \textit{post-experiment} coincidence inelastic neutron scattering (cINS). By coincidence detection of two photoelectric processes or two neutron-scattering processes, the \textit{post-experiment} coincidence detection techniques can detect directly the two-body correlations of strongly correlated electrons in particle-particle channel or two-spin channel. The \textit{post-experiment} coincidence detection techniques can be implemented upon the \textit{pulse}-resolved angle-resolved photoemission spectroscopy (ARPES) or inelastic neutron scattering (INS) experimental apparatus with \textit{pulse} photon or neutron source. When implemented experimentally, they will be powerful techniques to study the highly esoteric high-temperature superconductivity and the highly coveted quantum spin liquids. |
