Scattering theory of delicate topological insulators

Penghao Zhu, Jiho Noh, Yingkai Liu +1

We study the scattering theory of delicate topological insulators (TIs), which are novel topological phases beyond the paradigm of the tenfold way, topological quantum chemistry, a…

Spin Hopf Insulator: Helical Hinge States and Returning Thouless Pump

Penghao Zhu, A. Alexandradinata, Taylor L. Hughes

We introduce a time-reversal-symmetric analog of the Hopf insulator that we call a spin Hopf insulator. The spin Hopf insulator harbors nontrivial Kane-Mele invariants on it…

Higher rank chirality and non-Hermitian skin effect in a topolectrical circuit

Penghao Zhu, Xiao-Qi Sun, Taylor L. Hughes +1

While chirality imbalances are forbidden in conventional lattice systems, non-Hermiticity can effectively avoid the chiral-doubling theorem to facilitate 1D chiral dynamics. Indeed…

Spin-Resolved Topology and Partial Axion Angles in Three-Dimensional Insulators

Kuan-Sen Lin, Giandomenico Palumbo, Zhaopeng Guo +8

Symmetry-protected topological crystalline insulators (TCIs) have primarily been characterized by their gapless boundary states. However, in time-reversal- (-) invaria…

Spin-momentum locking from topological quantum chemistry: applications to multifold fermions

Mao Lin, Iñigo Robredo, Niels B. M. Schröter +3

In spin-orbit coupled crystals, symmetries can protect multifold degeneracies with large Chern numbers and Brillouin zone spanning topological surface states. In this work, we expl…
