Engineering Moiré Meta-crystals with Conventional Photonic and Phononic Structures
Mourad Oudich, Xianghong Kong, Tan Zhang +2
Recent discoveries on Mott insulating and unconventional superconducting states in twisted bilayer graphene with Moiré superlattices have reshaped the landscape of ''twistronics''…
Twist-angle and thickness-ratio tuning of plasmon polaritons in twisted bilayer van der Waals films
Chong Wang, Yuangang Xie, Junwei Ma +13
Stacking bilayer structures is an efficient way to tune the topology of polaritons in in-plane anisotropic films, e.g., by leveraging the twist angle (TA). However, the effect of a…
Airy-like hyperbolic shear polariton in high symmetry van der Waals crystals
Yihua Bai, Qing Zhang, Tan Zhang +7
Controlling light at the nanoscale by exploiting ultra-confined polaritons - hybrid light and matter waves - in various van der Waals (vdW) materials empowers unique opportunities…
Flat optical conductivity in the topological kagome magnet TbMnSn
R. S. Li, Tan Zhang, Wenlong Ma +13
Kagome magnet TbMnSn is a new type of topological material that is known to support exotic quantum magnetic states. Experimental work has identified that TbMnSn hos…
Negative reflection and negative refraction in biaxial van der Waals materials
Tan Zhang, Chunqi Zheng, Zhi Ning Chen +1
Negative reflection and negative refraction are exotic phenomena that can be achieved by platforms such as double-negative metamaterial, hyperbolic metamaterial, and phase-disconti…
The Role of Shift Vector in High-Harmonic Generation from Non-Centrosymmetric Topological Insulators under Strong Laser Fields
Chen Qian, Chao Yu, Shicheng Jiang +6
As a promising avenue to obtain new extreme ultraviolet light source and detect electronic properties, high-harmonic generation (HHG) has been actively developed in both theory and…
An Calculation Scheme for Large-Scale Moiré Structures
Tan Zhang, Nicolas Regnault, B. Andrei Bernevig +2
We present a two-step method specifically tailored for band structure calculation of the small-angle moiré-pattern materials which contain tens of thousands of atoms in a unit cell…
BaHgSn: A Dirac semimetal with surface hourglass fermions
Tan Zhang, Zhihai Cui, Zhijun Wang +2
We proposed that BaHgSn is a Dirac semimetal (DSM) which can host hourglass-like surface states (HSSs) as protected by nonsymmorphic glide symmetry. Compared to KHgSb, an isostruct…
Layer Construction of Topological Crystalline Insulator LaSbTe
Yuting Qian, Zhiyun Tan, Tan Zhang +5
Topological crystalline insulator (TCI) is one of the symmetry-protected topological states. Any TCI can be deformed into a simple product state of several decoupled two-dimensiona…
Temperature-induced band shift in ferromagnetic Weyl semimetal Co3Sn2S2
Run Yang, Tan Zhang, Liqin Zhou +4
The discovery of nonmagnetic Weyl semimetals (WSMs) in TaAs compounds has triggered lots of efforts in finding its magnetic counterpart. While the direct observation of the Weyl no…
Topological Crystalline Insulators with Rotation Anomaly
Tan Zhang, Changming Yue, Tiantian Zhang +5
Based on first-principles calculations and symmetry-based indicator analysis, we find a class of topological crystalline insulators (TCIs) with rotation anomaly in a family o…
