Transmission gap, Bragg-like reflection, and Goos-Hänchen shifts near the Dirac point inside a negative-zero-positive index metamaterial slab
Xi Chen, Li-Gang Wang, Chun-Fang Li
Motivated by the realization of the Dirac point (DP) with a double-cone structure for optical field in the negative-zero-positive index metamaterial (NZPIM), the reflection, transm…

The reversibility of the Goos-Hänchen shift near the band-crossing structure of one-dimemsional photonic crystals containing left-handed metamaterials
Li-Gang Wang, Shi-Yao Zhu
We perform a theoretical investigation on the Goos-Hächen (GH) shift in one-dimensional photonic crystals (1DPCs) containing left-handed metamaterials (LHMs). We find an unusal eff…

Fidelity and Fidelity Susceptibility of Pulses in Dispersive Media
Li-Gang Wang, Shi-Jian Gu
Motivated by the growing importance of the fidelity and fidelity susceptibility (FS) in quantum critical phenomena, we use these concepts to describe the pulse propagation inside t…
