In a flat Bloch band, the kinetic energy is quenched and single particles cannot propagate
since they are localized due to destructive interference. Whether this remains true in the …

We study the optical response of nanoribbons made from the α− T 3 lattice under a weak
magnetic field in the terahertz to far-infrared regime. It is found that the magnetic field can …

We study the electronic contribution to the nonlinear optical response of the α-T 3 model.
This model is an interpolation between a graphene (α= 0) and dice (α= 1) lattice. Using a …

Whether there is a minimal conductivity in the α-T 3 model or not is still in debate. By
considering the evanescent modes contributing to the zero-energy conductivity, we showed …

We review some recent progress in the exploration of pseudospin-1 physics using dielectric
photonic crystals (PCs). We show some physical implications of the PCs exhibiting an …

The nondispersive flat band in the α-T 3 model leads to a conventional integer quantum Hall
effect (IQHE) for Dirac particles as well as the existence of the zero Hall-conductivity plateau …

When a static electrical field is applied to a two-dimensional (2D) Dirac material, Landau-
Zener transition (LZT) and Bloch-Zener oscillations can occur. Employing α-T 3 lattices as a …

Mechanical deformations in α-T 3 lattices induce local pseudomagnetic fields of opposite
directionality for different valleys. When this strain is equipped with a dynamical drive, it …

We study theoretically Anderson localization of two-dimensional massless pseudospin-1
Dirac particles in a random one-dimensional scalar potential. We focus explicitly on the …

The phenomenon of super scattering was previously found to arise in massless pseudospin-
1 two-dimensional Dirac material systems with a flat band. Here we report the phenomenon …
