We generalize Wentzel-Kramers-Brillouin (WKB) semiclassical equations for pseudospin-1
α− T 3 materials with arbitrary hopping parameter 0< α< 1, which includes the dice lattice …

We investigate the quantum tunneling properties through a square potential barrier in the α-
T_3 α-T 3 model with an effective mass term. The additional mass term can be induced by …

Along with the studies of the properties of optical microcavities, the optical nonlinear effects
of the material and the interaction between light and matter are becoming important topics …

In his 1987 best seller Chaos: Making a New Science, science journalist James Gleick
wrote,“Where chaos begins, classical science stops.” Indeed, after relativity and quantum …

We study electron scattering from a closed magnetic structure embedded in the top surface
of a topological insulator. Outside the structure there is a uniform layer of ferromagnetic …

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 …

The phenomenon of spin-dependent quantum scattering in two-dimensional (2D)
pseudospin-1/2 Dirac materials leading to a relativistic quantum chimera was recently …

Metasurfaces are sub-wavelength patterned layers for controlling waves in physical
systems. In optics, meta-surfaces are created by materials with different dielectric constants …

Localized surface plasmon and Klein tunneling resonances are two phenomena that were
previously thought to be unrelated, where the former plays an important role in …
