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 [...]

Wigner instability analysis of the damped Hirota equation

Authors: Assaubay, Al-Tarazi; Castro, Alejandro J.; Valido, Antonio A. Contribution: Review Journal: PHYSICA D-NONLINEAR PHENOMENA Publication date: 2020/10/01 DOI: 10.1016/j.physd.2020.132587 Abstract: We address the modulation instability of the Hirota equation in the presence of stochastic spatial incoherence and linear time-dependent amplification/attenuation processes via the Wigner function approach. We show that the modulation instability remains baseband type, [...]
