There are moments when a question doesn’t feel like a question. It feels like a memory. For me it happened while staring at a picture of graphene, one of those endlessly repeating hexagonal lattices ...
Quantum geometry gives rise to many fascinating phenomena in solids that go beyond Landau theory. A general framework is now introduced to measure the quantum geometric tensor in solids — a ...
Luan, Blaschke, Isshiki, Guan, Pauly, Meyhofer, and Reddy showed that replacing a single hydrogen atom on the phenyl ring of 1,4-benzenediamine with a heavier halogen steadily suppresses phonon ...
