Magnetically brightened dark electron-phonon bound states in a van der Waals antiferromagnet
Abstract
Van der Waals materials can exhibit strong coupling between the lattice and other degrees of freedom. Here, Ergeçen et al reveal the presence of bound states emerging from the strong interaction between the lattice vibrations and d-orbitals in the van der Waals antiferromagnet NiPS3.
