Chiral Phonons Coupled to Spin-Split Bands in Altermagnetic CrSb and MnTe
Armando Consiglio, Maximilian Ãnzelmann, Giancarlo Panaccione +1
Altermagnets exhibit momentum-dependent spin splitting without net magnetization, providing a unique platform where magnetic order, electronic structure and lattice dynamics intert…
Observation and Control of Moiré-Tailored Topological Dirac States
R. Ganser, M. P. T. Masilamani, B. Geldiyev +6
Moiré heterostructures provide a powerful framework for tailoring electronic band structures via controlled long-range periodic superlattice potentials. Beyond widely studied moir…
Direct experimental access to the bulk band inversion in a topological metamaterial
Simon Widmann, Johannes Düreth, Siddhartha Dam +9
Topological phases in exciton-polaritons and other metamaterial platforms have attracted significant attention due to their flexibility as Hamiltonian simulators. In previous works…
Zero-energy band observation in an interfacial chalcogen-organic network
Yichen Jin, Ignacio Gonzalez Oliva, Hibiki Orio +12
Structurally-defined molecule-based lattices such as covalent organic or metal-organic networks on substrates, have emerged as highly tunable, modular platforms for two-dimensional…
Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
