DOI: 10.1088/1402-4896/ad6d0b
Abstract: The concept of topological Fano resonance, characterized by an ultrasharp asymmetric line shape, is a promising candidate for robust sensing applications due to its sensitivity to external parameters and immunity to structural disorder. In this… read more here.

DOI: 10.1103/physrevb.107.205408
Abstract: While one of the most important and intriguing features of the topological insulators is the presence of edge states, the closed-form expressions for the edge states of some famous topological models are still lacking. Here,… read more here.

DOI: 10.1103/physrevb.111.035411
Abstract: In this work, we use the local spin Chern marker (LSCM) recently introduced by Ba\`{u} and Marrazzo [Phys. Rev. B 110, 054203 (2024)] to analyze the topology of the ground-state electronic wave functions in a… read more here.

DOI: 10.1103/physrevb.98.054203
Abstract: In this work we use Floquet theory to theoretically study the influence of circularly polarized light on disordered two-dimensional models exhibiting topological transitions. We find circularly polarized light can induce a topological transition in extended… read more here.
