Observation of Quantized Klein Tunneling in a Dielectric Resonator Chain
Rui-Jie Zhang, Xiao-Zhen Peng, Ri-Zhen Yang +4
We present the first experimental observation of quantized Klein tunneling in a bounded Dirac system, implemented by a dimer chain of dielectric microwave resonators. Both the unus…

Symmetry dictated universal helicity redistribution of Dirac fermions in transport
Jun-Yin Huang, Rui-Hua Ni, Hong-Ya Xu +1
Helicity is a fundamental property of Dirac fermions. Yet, the general rule of how it changes in transport is still lacking. We uncover, theoretically, the universal spinor state t…
