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…
First-order phase transition vs. spin-state quantum-critical scenarios in strain-tuned epitaxial cobaltite thin films
J. E. Dewey, V. Chaturvedi, T. A. Webb +12
Pr-containing perovskite cobaltites exhibit unusual valence transitions, coupled to coincident structural, spin-state, and metal-insulator transitions. Heteroepitaxial strain was r…
Room-Temperature Valence Transition in a Strain-Tuned Perovskite Oxide
Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau +17
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very dif…
