Project B04 investigates excitons in mol2Dmat heterostructures using time-resolved ARPES to identify signatures of exciton condensation into an excitonic insulator. It focuses on molecule/TiSe₂ and molecule/Ta₂NiSe₅ systems to distinguish between excitonic insulator and pure charge-density-wave phase, and on molecule/WS₂ to study energy level alignment, charge-transfer exciton formation, and their ultrafast dynamics.

Experimental methods: time- and angle-resolved photoemission spectroscopy (tr-ARPES)
