  • Transient optical spectroscopy applied to studying twisted MoTe2 for time-domain detection of fractional fillings of Chern bands reveals many hidden states that have not been previously observed and which could host exotic topological phases.

  • Experimental evidence for charge coupling to ferroelectric soft mode is scarce. Here, the authors find a photogenerated coherent phonon coupling to the electronic transition above the bandgap in the van der Waals ferroelectric semiconductor NbOI2.

  • The authors use angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) to study the charge density wave (CDW) in the kagome material ScV6Sn6. The ARPES data shows minimal changes to the electronic structure in the CDW state, while STM quasiparticle interference measurements imply a strong reconstruction of the electronic structure in the CDW state.
