A team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has identified a rare, ...

Chiral zeroth Landau levels are topologically protected bulk states that propagate in a single direction. In the field of quantum field theory and condensed matter physics, these levels are crucial ...

(a) Ideal homogenous zero-index medium. (b) Zero-index medium’s applications in free-space cloak, arbitrarily shaped waveguide, and photonic crystal surface emitting laser. (c) Schematic of Dirac-cone ...

At the heart of Dirac materials' unique properties is the Dirac cone, a linear dispersion of the electronic band structure near the Fermi level. This feature results in electrons moving through the ...
