A Tight-binding Approach for Computing Subwavelength Guided Modes in Crystals with Line Defects
Habib Ammari, Erik Orvehed Hiltunen, Ping Liu +2
In this paper, we develop an accurate and efficient framework for computing subwavelength guided modes in high-contrast periodic media with line defects, based on a tight-binding a…
Pseudo-magnetic Fields and Effective Dynamics in Strained Honeycomb Structures
Chengyu Zhang, Borui Miao, Yi Zhu
Strain offers an effective method for generating pseudo-magnetic fields in optical and acoustic materials, thereby enabling precise manipulation of wave propagation. In this articl…
Zero-energy Edge States of Tight-Binding Models for Generalized Honeycomb-Structured Materials
Borui Miao, Yi Zhu
Generalized honeycomb-structured materials have received increasing attention due to their novel topological properties. In this article, we investigate zero-energy edge states in…
Edge states in super honeycomb structures with PT-symmetric deformations
Ying Cao, Yi Zhu
The existence of edge states is one of the most vital properties of topological insulators. Although tremendous success has been accomplished in describing and explaining edge stat…
Generalized Honeycomb-structured Materials in the Subwavelength Regime
Borui Miao, Yi Zhu
Honeycomb structures lead to conically degenerate points on the dispersion surfaces. These spectral points, termed as Dirac points, are responsible for various topological phenomen…
Double Dirac cones in band structures of periodic Schrödinger operators
Ying Cao, Yi Zhu
Dirac cones are conical singularities that occur near the degenerate points in band structures. Such singularities result in enormous unusual phenomena of the corresponding physica…
