Authors: Rubio-Garcia, Alvaro; Self, Chris N.; Jose Garcia-Ripoll, Juan; Pachos, Jiannis K. Contribution: Article Journal: PHYSICAL REVIEW B Publication date: 2020/07/23 DOI: 10.1103/PhysRevB.102.041123 Abstract: Here we provide a general methodology to directly measure the topological currents emerging in the optical lattice implementation of the Haldane model. Alongside the edge currents supported by gapless edge states, transverse [...]

Topological bulk states and their currents

Authors: Self, Chris N.; Rubio-Garcia, Alvaro; Jose Garcia-Ripoll, Juan; Pachos, Jiannis K. Contribution: Article Journal: PHYSICAL REVIEW B Publication date: 2020/07/23 DOI: 10.1103/PhysRevB.102.045424 Abstract: We provide evidence that, alongside topologically protected edge states, two-dimensional Chern insulators also support localized bulk states deep in their valence and conduction bands. These states manifest when local potential gradients are [...]
