Visualizing Berry curvature in a Floquet-Chern insulator
Younsik Kim, Rishi Acharya, Hannah E. Aguirre +3
Circularly polarized light can open a topological gap in a gapless Dirac system, creating a Floquet-Chern insulator. However, its Berry curvature has not been directly resolved. He…

High temperature Jahn-Teller distortion and short-range order in CsCuCl
Emma A. Pappas, Toby Woods, Jue Liu +1
CsCuCl, chiral and Jahn-Teller distorted at room temperature, takes a more symmetric structure above 423 K. Describing this 'simpler' high temperature structure is far from sim…

Dynamic competition between phason and amplitudon observed by ultrafast multimodal scanning tunneling microscopy
Seokjin Bae, Arjun Raghavan, Soyeun Kim +7
The intertwining between two ordered states that arise from the same interactions is reflected in the dynamics of their coupled collective excitations. While the equilibrium phase…
