We introduce a two-dimensional dimerized lattice model that reveals a remarkable feature: the emergence of a complex, non-trivial topological multiferroic phase marked by zero Berry curvature and a significant Berry connection that influences the model’s bulk topology. This model extends the one-dime...

However, the investigation on the mechanism of magnetic properties, especially the exchange interactions between R-Mn and the magnetic coupling of RMn6Sn6 are still lacking from either experimental or theoretical aspects16,17, which is critical for exploring their topological properties and the ...

We also find that, for systems with "antiferromagnetic symmetry," there is a Z2 classification in three-dimensions, and hence a class of "antiferromagnetic topological insulators" (AFTIs) which are distinguished from ordinary antiferromagnets. From the perspective of the bulk, AFTI exhibits the ...

In 4d gauge theories for example, the expectation values of Wilson lines and 't Hooft lines can be used to distinguish different phases [1, 2], while line operators and their correlation functions capture many aspects of the global structure [3–5]. In condensed matter physics, line defects...
