3D nonlinear optical metamaterials from twisted 2D van der Waals interfaces
Bumho Kim, Jicheng Jin, Zhi Wang +4
To enable new nonlinear responses, metamaterials are created by organizing structural units (meta-atoms) which are typically on the scale of about a hundred nanometers. However, tr…
The effects of intrinsic local distortions vs. dynamic thermal motions on the stability and band gaps of cubic oxide and halide perovskites
Xin-Gang Zhao, Zhi Wang, Oleksandr I. Malyi +1
Corner-shared ABX perovskites have long featured prominently in solid-state chemistry and condensed matter physics. Still, the joint understanding of their two main subgroups-h…
Strong influence of non-magnetic ligands on the momentum dependent spin splitting in antiferromagnets
Lin-Ding Yuan, Zhi Wang, Jun-Wie Luo +1
Recent studies have shown that the non-relativistic antiferromagnetic ordering could generate momentum-dependent spin splitting analogous to the Rashba effect, but free from the re…
Spin-orbit driven ferromagnetism at half moiré filling in magic-angle twisted bilayer graphene
Jiang-Xiazi Lin, Ya-Hui Zhang, Erin Morissette +7
Strong electron correlation and spin-orbit coupling (SOC) provide two non-trivial threads to condensed matter physics. When these two strands of physics come together, a plethora o…
Thermal Transport in Polymers: A Review
Xingfei Wei, Zhi Wang, Zhiting Tian +1
In this article, we review thermal transport in polymers with different morphologies from aligned fibers to bulk amorphous states. We survey early and recent efforts in engineering…
Prediction of low-Z collinear and noncollinear antiferromagnetic compounds having momentum-dependent spin splitting even without spin-orbit coupling
Lin-Ding Yuan, Zhi Wang, Jun-Wei Luo +1
Recent study (Yuan et. al., Phys. Rev. B 102, 014422 (2020)) revealed a SOC-independent spin splitting and spin polarization effect induced by antiferromagnetic ordering which do n…
Mass enhancement in 3d and s-p perovskites from symmetry breaking
Zhi Wang, Oleksandr I. Malyi, Xingang Zhao +1
In some d-electron oxides the measured effective mass m(exptl) has long been known to be significantly larger than the model effective mass m(model) deduced from mean-field band th…
Tuning electron correlation in magic-angle twisted bilayer graphene using Coulomb screening
Xiaoxue Liu, Zhi Wang, K. Watanabe +3
The ability to control the strength of interaction is essential for studying quantum phenomena emerging from a system of correlated fermions. For example, the isotope effect illust…
Giant momentum-dependent spin splitting in centrosymmetric low Z antiferromagnets
Lin-Ding Yuan, Zhi Wang, Jun-Wei Luo +2
The energy vs. crystal momentum E(k) diagram for a solid (band structure) constitutes the road map for navigating its optical, magnetic, and transport properties. By selecting crys…
Understanding Electronic Peculiarities in Tetragonal FeSe as Local Structural Symmetry Breaking
Zhi Wang, Xingang Zhao, Robert Koch +2
Traditional band theory of perfect crystalline solids often uses as input the structure deduced from diffraction experiments; when modeled by the minimal unit cell this often produ…
