Observing vibrational coherences which appear as quantum beats on a spectrograph, and catching an elusive quasiparticle-Exciton polaron. The spectrograph records a projection of macroscopic ...

Topological defects are the key feature mediating two-dimensional phase transitions. However, both resolution and tunability have been lacking to access the dynamics of these transitions in the ...

Lattice symmetry directly shapes topological spin structures in two-dimensional van der Waals magnets, a role typically attributed to interfacial interactions. Mapping spin textures whose outlines ...

Non-symmorphic symmetries protect Dirac nodal lines and cones in lattice systems. Here, we investigate the spectral properties of a two-dimensional lattice belonging to a non-symmorphic group.
