Moiré superlattices host a rich variety of correlated electronic phases. However, the moiré
potential is fixed by interlayer coupling, and it is dependent on the nature of carriers and …

New developments in superconductivity, particularly through unexpected and often
surprising forms of superconducting materials, continue to excite the community and …

Atomically thin semiconductors such as transition metal dichalcogenide (TMD) monolayers
exhibit a very strong Coulomb interaction, giving rise to a rich exciton landscape. This makes …

Strain engineering is a powerful tool in designing artificial platforms for high-temperature
excitonic quantum devices. Combining strong light-matter interaction with robust and mobile …

Interlayer excitons (IXs), composed of electron and hole states localized in different layers,
excel in bilayers composed of atomically thin van der Waals materials such as …

Exciton transport in two-dimensional Ruddlesden− Popper perovskite plays a pivotal role for
their optoelectronic performance. However, a clear photophysical picture of exciton transport …

Propagation of light-emitting quasiparticles is of central importance across the fields of
condensed matter physics and nanomaterials science. We experimentally demonstrate …

We report on the spatial coherence of interlayer exciton ensembles as formed in MoSe
2/WSe 2 heterostructures and characterized by point-inversion Michelson-Morley …

Exciton-exciton interactions are key to understanding nonlinear optical and transport
phenomena in van der Waals heterobilayers, which emerged as versatile platforms to study …

The interaction of excitons with lattice vibrations underlies the scattering from bright to dark
excitons as well as the coherent modulation of the exciton energy. Unlike the former …
