The recent realization of topology as a mathematical concept in condensed matter systems
has shattered Landau's widely accepted classification of phases by spontaneous symmetry …

This paper proposes a multichannel terahertz optical filter based on a one-dimensional
photonic crystal with a third-order Fibonacci structure, including a bulk Dirac semimetal. The …

Highly localized electromagnetic field distributions near the “shadow-side” surface of certain
transparent mesoscale bodies illuminated by light waves are called photonic jets. We …

Exploiting the extraordinary transport and optical properties of 3D topological semimetals for
device applications requires epitaxial integration with semiconductors to carefully control …

A bulk crystal of cadmium arsenide is a three-dimensional Dirac semimetal, but, in a thin
film, it can behave like a three-dimensional topological insulator. This tunability provides …

There is a need for compact, dynamically tunable, nonreciprocal optical elements to enable
on-chip-compatible optical isolators and more efficient radiative energy transfer systems …

Electronic devices that operate at terahertz frequencies will require new materials that
exhibit higher carrier velocities than traditional semiconductors. Calculations show that …

Topological protection against localization causes electrical transport phenomena in
disordered topological materials to differ from those in topologically trivial systems. For …

The three-dimensional Dirac semimetal is a parent phase for a variety of topological phases
that can be generated by tuning parameters in material growth or device operation. Notably …

Recently, we have demonstrated helicity-dependent photocurrent (HDPC) in strain-free
Dirac semimetal Cd 3 As 2 nanobelts at room temperature. Here, we investigate their …
