Second Chern crystals in four-dimensional synthetic translation space with inherently nontrivial topology
Xiao-Dong Chen, Fu-Long Shi, Jian-Wei Liu +4
Topological states, first known as quantum Hall effect or Chern insulating crystal, have been generalized to many classical wave systems where potential applications such as robust…
Topology in non-Hermitian Chern insulators with skin effect
Yi-Xin Xiao, C. T. Chan
The non-Hermitian skin effect can arise in materials that have asymmetric hoppings between atoms or resonating units, which makes the bulk eigenspectrum sensitive to boundary condi…
Four-band non-Abelian topological insulator and its experimental realization
Tianshu Jiang, Qinghua Guo, Ruo-Yang Zhang +3
Very recently, increasing attention has been focused on non-Abelian topological charges, e.g. the quaternion group Q8. Different from Abelian topological band insulators, these sys…
Photonic nodal lines with quadrupole Berry curvature distribution
Dongyang Wang, Biao Yang, Ruo-Yang Zhang +4
In periodic systems, nodal lines are loops in the three-dimensional momentum space where two bands are degenerate with each other. Nodal lines exhibit rich topological features as…
