Helicity-resolved magneto-photoluminescence reveals that the unequal spacing of the dipolar exciton ladder in R-stacked WSe₂/WS₂ arises from triplet and singlet spin-valley two-exciton states, not simple occupation-number physics.
Atν= 1, the PL spectrum consists of IX ′ 1, IX′ 2, and two additional resonances at 1.461 eV and 1.483 eV, denoted IX′ 3 and IX′ 4, respectively

Unveiling the Spin-Valley Structure of Dipolar Exciton Ladders in R-stacked WSe$_2$/WS$_2$ Moir\'e Heterobilayers
Helicity-resolved magneto-photoluminescence reveals that the unequal spacing of the dipolar exciton ladder in R-stacked WSe₂/WS₂ arises from triplet and singlet spin-valley two-exciton states, not simple occupation-number physics.
